<hr />
<div>This page is a starting point for resources for using the Jetson Nano (with or without a Portsdown) to drive a LimeSDR to transmit DATV.<br />
<br />
John G7JTT has written up his experiences on the BATC forum: https://forum.batc.org.uk/viewtopic.php?t=6402&p=21487#p21487<br />
<br />
The control of the Jetson Nano from the Portsdown is an "Unsupported Feature". This means that we will make best efforts to keep it working, but it is still somewhat experimental.<br />
<br />
===G8GKQ's Installation Procedure===<br />
<br />
To start with, you need a Jetson Nano, a 32 GB SD Card (Sandisk Ultra 10 recommended), a 4A 5V PSU with a 2.1mm power plug, a 0.1 inch jumper, an HDMI monitor, a USB Mouse and a USB keyboard.<br />
<br />
Download the Jetson Nano disk image to a PC and unzip it. Use Win32 Disk Imager or Etcher to write it to your SD Card. These instructions are based on the jetson-nano-sd-r32.1-2019-03-18 image and will not work with later images. An updated set of instructions is being prepared.<br />
<br />
Fit the jumper link to the Nano PCB at J48 to select the use of the 2.1mm power socket, insert the SD Card, connect the monitor, keyboard and mouse. Connect the Nano to your home network and then connect the power and turn it on. Go through the NVIDIA start up routine so that you have a working Nano connected to your network. I used the username "nano" and the password "jetson". These are weak and obvious and should only be used on private networks, but make scripting easy.<br />
<br />
Note that the process may seem to freeze on "waiting for unattended-upgr to exit" for around 30 minutes, this is expected, the system is automatically updating software in the background.<br />
<br />
Right-click on the desktop and open a terminal window. Run the following commands. You will need to enter the password occasionally.<br />
<br />
sudo apt-get update<br />
sudo apt-get -y dist-upgrade<br />
sudo apt-get -y install git htop nano vlc v4l-utils<br />
<br />
You are now ready to install the DATV software.<br />
<br />
===Installing DATV Software===<br />
<br />
Download and install the software from F5OEO's repository:<br />
<br />
git clone https://github.com/F5OEO/dvbsdr<br />
cd dvbsdr<br />
./install.sh<br />
<br />
===Preparing the LKV373A HDMI Device===<br />
<br />
The LKV373A should be a transmitter (Sender) and of hardware version 3.0 as shown here:<br />
<br />
[[File:LKV373A Topside.jpg|246px]] [[File:LKV373A Underside.jpg|200px]]<br />
<br />
This is probably the most difficult part of the software installation. More details to follow in CQ-TV, but I upgraded the firmware (not encoder) to 20160427 using the instructions here: https://www.yodeck.com/docs/display/YO/Creating+a+Video-Wall+with+Yodeck#CreatingaVideo-WallwithYodeck-J.ConfiguringtheLKV373ASenderunit . These are at the end of the very long web page. The firmware is here [[:File:IPTV_TX_PKG_v4_0_0_0_20160427.zip]]<br />
<br />
Dave also set the unit to factory defaults, but did not change any other settings. The PuTTy settings to carry out the factory reset per Yodeck.com instructions with your own device IP address look like the following:-<br />
<br />
[[File:PuTTy_for_HDMI_sender_reset.PNG|300px]] [[File:IPTV_server_web_page_at_completion.PNG|300px]]<br />
<br />
After the firmware upgrade, the username and password for the LKV373A is admin/123456. Then the IP address webpage of the device will look like the top right image. <br />
<br />
If you have issues with the firmware upgrade, recovery might be possible using the IPV Tools application found here: https://drive.google.com/drive/u/0/folders/0B3mWuDyxrXyKSTZZZlRESlpBZmM.<br />
<br />
At various times during the LKV373A set-up, it had the following IP addresses: 192.168.1.238, 10.1.0.99, 10.1.2.99, and 169.254.113.227.<br />
<br />
The address for the stream is almost always udp://@239.255.42.42:5004 (you can paste this into VLC on a PC and watch the stream). Note that you cannot view the stream using VLC on the Jetson Nano - for some reason it does not work.<br />
<br />
For more information about the LKV373A [https://www.youtube.com/watch?v=SAvGylthpkU try this video from OpenTechLabs on YouTube].<br />
<br />
===Modifying the Scripts===<br />
<br />
To transmit using the Nano and this script, you will need to plug a LimeSDR Mini into it. '''If you are NOT controlling it from the Portsdown, you will also need to modify the script ~/dvbsdr/scripts/jetson_nano.sh.''' Note that if you are using Portsdown control, you can skip this step. <br />
<br />
The only input devices that work with this script are the LKV373A, and the Pi Cam when connected to the Jetson board. The PiCam will not work without a USB microphone dongle connected to the Jetson board - without this it never transmits a picture.<br />
<br />
The C920, although referenced in some of the code, does not work with this script.<br />
<br />
The working script is here:<br />

Most of this is self-explanatory. Note that "short frames" do not work.<br />
<br />
===Transmitting using the Script===<br />
<br />
cd ~/dvbsdr/scripts<br />
./jetson_nano.sh<br />
<br />
To stop transmitting, simply press ctrl-c.<br />
<br />
===Update - Control from Portsdown Touchscreen===<br />
<br />
Version 201906060 of the Portsdown Software (currently only available as a Development Release) introduces experimental control of a Jetson Nano set up as above from the Portsdown touchscreen.<br />
<br />
To set this up, load the development release, and then go to Menu 3, Jetson Config.<br />
On the Jetson Configuration Menu, you need to set up:<br />
* The Jetson username<br />
* The Jetson password<br />
* The Jetson root password<br />
* The Jetson IP Address<br />
* The LKV373A UDP broadcast address<br />
* The LKV373A UDP port<br />
<br />
If you have used the setup instructions above, you should only need to change the Jetson IP Address.<br />
<br />
Once the IP Address is correct, the Shutdown and Reboot buttons should turn from Grey to Green indicating that the Raspberry Pi can ping the Jetson.<br />
<br />
After you have done this, use the touchscreen to select:<br />
* Output to: Jetson Lime<br />
* Encoder: H264 or H265<br />
* Source: HDMI, Pi Cam or C920 (note that the Pi Cam OR the C920 should be connected to the Jetson, not the RPi)<br />
<br />
'''Note that only one of the C920 or Pi Cam should be connected at any time. Connecting both at once disables both.'''<br />
<br />
Then you can select other settings (Modulation, Frequency, Symbol Rate, FEC and Lime Gain) as required. Testing has only been conducted over a narrow range of SRs and FECs. 500KS, FEC 1/2 is a good starting point.<br />
<br />
When you shut down your Portsdown using the touchscreen ShutDown button, it will send a ShutDown signal to the Jetson as well, allowing a graceful shutdown of the Jetson without the use of a screen and keyboard.<br />
<br />
The GPIO pin 40 on the Jetson can be used to key PAs as it is programmed to go high 15 seconds after TX selection and go low at the end of the transmission. However, please see the warning about GPIO behaviour below.<br />
<br />
===Portsdown Control Problems===<br />
<br />
If you have trouble controlling the Nano from the Portsdown, try a manual ssh session from the Pi to the Jetson. You may find that you have to update the trust certificate. Thanks to G0MJW for suggesting this one!<br />
<br />

=== GPIO ===<br />
<br />
The GPIO pinout of the Jetson Nano can be found here: https://www.jetsonhacks.com/nvidia-jetson-nano-j41-header-pinout/<br />
<br />
Note that when not initialised in sysfs (ie. straight after power-on), the GPIO pins appear to be able to be latched up from their default 0V state to a 3.3V high, or an unstable ~1.4V state by simply touching a scope or multimeter probe to the pin. The exact characteristic of this behaviour isn't yet understood but it is worrying for PA PTT control and similar applications.<br />
<br />
=== Fan ===<br />
<br />
PWM fans are available however the use of a non-PWM 5V fan will cause the fan to simply run all the time (including when the Jetson is shutdown), removing the requirement for the fan to be manually started in software after boot. When using PWM, set a value where the fan runs slowly but reliably to minimise noise. There is some code here https://github.com/Pyrestone/jetson-fan-ctl or here https://github.com/hooperbill/fan-daemon for automatic fan speed control. Manually:<br />
<br />
sudo sh -c 'echo XXX > /sys/devices/pwm-fan/target_pwm' where XXX is a number between 0 and 255 setting the PWM speed.<br />
<br />
The holes in the heatsink can be tapped for M3 bolts, or can be drilled out. Note that the fins below the holes prevent more than ~3mm of the bolt from protruding below.</div>G8XZDhttps://wiki.batc.org.uk/index.php?title=GB3ZZ&diff=9827GB3ZZ2022-06-15T22:43:17Z<p>G8XZD: </p>

<div>'''GB3ZZ has returned to action after losing its original site last year''' <br />
<br />
Although the move was just across the car park, the aerials are now lower than before and closer to nearby houses. Early tests suggest the signals are<br />
down in certain directions but more work needs to be done to verify this. Any reports are most welcome. <br />
<br />
Because of the cost of electricity ZZ is now operating as a "part time repeater" (0900-2100 GMT; 1000-2200 BST)<br />

<hr />
<div>Amateur television is a fascinating part of the hobby covering all aspects of video production, editing, transmission and reception of television signals - whether across town or across the world by the geostationary QO-100 satellite.<br />
<br />
One of the aims of the BATC is to help members get on the air. Probably the easiest way to achieve this is by using drone FM transmitter/receiver modules - take a [[5.6 GHz|look at this page]] which shows you how to join in the fun on 5.6GHz for around £20. <br />
<br />
This is enough to get good quality pictures over a few miles over line-of-sight paths with simple aerials - though with a better aerial and a good portable location at both ends of the link - it is possible to work hundreds of miles during favourable atmospheric conditions (the proverbial "bit of a lift on there old man").<br />
<br />
Alternatively the club has come up with the Portsdown project which is easy enough for most people to successfully build at home and gives you the basics of a very credible DATV transmitter (It can also be upgraded to receive DATV)<br />
<br />
The Portsdown is based around the popular Raspberry Pi 4 single board computer, an Adalm Pluto SDR, and controlled by a seven-inch touchscreen. <br />
<br />
Hundreds of these have been built by amateurs around the world and part of its success is down to the club prescribing the key components/design (and you sticking to them...) and following simple build instructions. <br />
<br />
Yes I know radio amateurs (me included) like to tinker and experiment but at this stage it really helps our volunteers help you. That way, if there are any problems, it's easy to offer support via the BATC forum. And if you still can't get it going bring it along to one of our Portsdown clinics which are held at most rallies the BATC attends.<br />
<br />
So let's run through the basics:<br />
<br />
<br />
'''The best way forward:'''<br />
<br />
We often get asked how do I start to receive or transmit DATV? <br />
<br />
Like most areas in amateur radio there are lots of ways to do this but let's spend our money (and time) wisely<br />
and put together something tried and tested.<br />
<br />
This approach means you are more likely to be successful, and if you really get into DATV, these building blocks can be reused to make even more sophisticated equipment.<br />
<br />
<br />
'''Receiving DATV:'''<br />
<br />
Probably the most repeatable way to do this is to build up a Minitiouner board. It was designed by Jean-Pierre Courjaud, F6DZP, and can be used with his <br />
excellent free MiniTioune Windows software.<br />
<br />
You can find out more on the Minitioune wiki page: https://wiki.batc.org.uk/MiniTioune <br />
<br />
The PCB and other "hard-to-get" components can be bought from the BATC shop https://batc.org.uk/shop/ - the remainder are standard leaded (no surface mount) components, available from all major suppliers. and can easily be put together in an evening. <br />
<br />
With this you can receive local DATV activity from 2m to 13cm, including digital TV repeaters, and with a satellite dish and LNB, you can watch the activity on QO-100.<br />
<br />
Jean-Pierre's software also comes with a suite of programmes to allow you to test that the board is talking to the software correctly.<br />
<br />
You will then need the normal aerials, filters/pre-amps and/or LNB depending on the band you want to receive. Having said that it is relatively sensitive enough on its own to<br />
be able to receive nearby activity - and probably your local digital TV repeater.<br />
<br />
Once you've tested the board works correctly and you want to upgrade tour receiver have a look at at the BATC Ryde DATV receiver project: https://wiki.batc.org.uk/Ryde_Receiver This is a set top box-style receiver based around the Raspberry Pi 4 and an infrared hand controller.<br />
<br />
The Ryde's main advantage is you don't need to have a PC on and it produces good quality pictures via an HDMI cable (you can use composite video if you must...) <br />
From the hand controller you just tell it the frequency and symbol rate - and it does the rest.<br />
<br />
<br />
'''DATV transmit:'''<br />
<br />
The BATC Portsdown system is the way go. It is Raspberry Pi 4-based but you can buy a pre-programmed SD card from BATC so there is no programming or computer wizardry at all. This plus a touch screen and a Pluto SDR, which simply plugs in to the Pi's USB socket, will give you a simple to use touch screen DATV transmit system. <br />
<br />
For more details see [[The Portsdown Transmitter|https://wiki.batc.org.uk/The_Portsdown_Transmitter]]<br />
<br />
Again if you want more information, or need some help, have a look in the Portsdown section of the BATC forum: https://forum.batc.org.uk/viewforum.php?f=103<br />
<br />
This basic system will give you a full blown DATV transmit system from 50MHz up to 3.4GHz with good picture quality. Again you will need filters and amplifiers for the band of your choice.<br />
<br />
<br />
'''DATV transmit and receive in one box:'''<br />
<br />
Since the release of Portsdown software in autumn 2019 that included the LongMynd receiver you can plug the MiniTiouner USB tuner hardware in to the Portsdown system and it will display the pictures, thereby becoming a full DATV transceiver and replacing the need for a PC. <br />
<br />
The Portsdown 4 software includes everything you need - just make sure you have the latest build - and plug your tuner card in to the Pi's USB port. See https://wiki.batc.org.uk/Portsdown_4_Pluto for more details.</div>G8XZDhttps://wiki.batc.org.uk/index.php?title=Getting_Started&diff=8617Getting Started2021-07-05T16:59:43Z<p>G8XZD: </p>

<div>Amateur television is a fascinating part of the hobby covering all aspects of video production, editing, transmission and reception of television signals - whether across town or across the world by the geostationary QO-100 satellite.<br />
<br />
One of the aims of the BATC is to help members get on the air. Probably the easiest way to achieve this is by using drone FM transmitter/receiver modules - take a [[5.6 GHz|look at this page]] which shows you how to join in the fun on 5.6GHz for around £20. <br />
<br />
This is enough to get good quality pictures over a few miles over line-of-sight paths with simple aerials - though with a better aerial and a good portable location at both ends of the link - it is possible to work hundreds of miles during favourable atmospheric conditions (the proverbial "bit of a lift on there old man").<br />
<br />
Alternatively the club has come up with the Portsdown project which is easy enough for most people to successfully build at home and gives you the basics of a very credible DATV transmitter (It can also be upgraded to receive DATV)<br />
<br />
The Portsdown is based around the popular Raspberry Pi 4 single board computer, an Adalm Pluto SDR, and controlled by a seven-inch touchscreen. <br />
<br />
Hundreds of these have been built by amateurs around the world and part of its success is down to the club prescribing the key components/design (and you sticking to them...) and following simple build instructions. <br />
<br />
Yes I know radio amateurs (me included) like to tinker and experiment but at this stage it really helps our volunteers help you. That way, if there are any problems, it's easy to offer support via the BATC forum. And if you still can't get it going bring it along to one of our Portsdown clinics which are held at most rallies the BATC attends.<br />
<br />
So let's run through the basics:<br />
<br />
<br />
'''The best way forward:'''<br />
<br />
We often get asked how do I start to receive or transmit DATV? <br />
<br />
Like most areas in amateur radio there are lots of ways to do this but let's spend our money (and time) wisely<br />
and put together something tried and tested.<br />
<br />
This approach means you are more likely to be successful, and if you really get into DATV, these building blocks can be reused to make even more sophisticated equipment.<br />
<br />
<br />
'''Receiving DATV:'''<br />
<br />
Probably the most repeatable way to do this is to build up a Minitiouner board. Developed by Jean-Pierre Courjaud, F6DZP, and can be used with his <br />
excellent free MiniTioune Windows software.<br />
<br />
You can find out more on the Minitioune wiki page: https://wiki.batc.org.uk/MiniTioune <br />
<br />
You can buy the PCB and other "hard-to-get" components from the BATC shop https://batc.org.uk/shop/ - the remainder are standard leaded (no surface mount) components, available from all major suppliers. and can easily be put together in an evening. <br />
<br />
With this you can receive local DATV activity from 2m to 13cm, including digital TV repeaters, and with a satellite dish and LNB, you can watch the activity on QO-100.<br />
<br />
Jean-Pierre's software also comes with a suite of programmes to allow you to test that the board is talking to the software correctly.<br />
<br />
You will then need the normal aerials, filters/pre-amps and/or LNB depending on the band you want to receive. Having said that it is relatively sensitive enough on its own to<br />
be able to receive nearby activity - and probably your local digital TV repeater.<br />
<br />
Once you've tested the board works correctly and you want to upgrade tour receiver have a look at at the BATC Ryde DATV receiver project: https://wiki.batc.org.uk/Ryde_Receiver This is a set top box-style receiver based around the Raspberry Pi 4 and an infrared hand controller.<br />
<br />
The Ryde's main advantage is you don't need to have a PC on and it produces good quality pictures via an HDMI cable (you can use composite video if you must...) <br />
From the hand controller you just tell it the frequency and symbol rate - and it does the rest.<br />
<br />
<br />
'''DATV transmit:'''<br />

The Portsdown is based around the popular Raspberry Pi 4 single board computer, an Adalm Pluto SDR, and controlled by a seven-inch touchscreen. <br />
<br />
Hundreds of these have been built by amateurs around the world and part of its success is down to the club prescribing the key components/design (and you sticking to them...) and following simple build instructions. <br />
<br />
Yes I know radio amateurs (me included) like to tinker and experiment but at this stage it really helps our volunteers help you. That way, if there are any problems, it's easy to offer support via the BATC forum. And if you still can't get it going bring it along to one of our Portsdown clinics which are held at most rallies the BATC attends.<br />
<br />
But if this all sounds overwhelming there's an easy way to "get on the air" using transmitter/receiver modules - if so take a [[5.6 GHz|look at this page]] which shows you how to join in the fun on 5.6GHz for around £20. <br />
<br />
So let's run through the basics:<br />
<br />
<br />
'''The best way forward:'''<br />
<br />
We often get asked how do I start to receive or transmit DATV? <br />
<br />
Like most areas in amateur radio there are lots of ways to do this but let's spend our money (and time) wisely<br />
and put together something tried and tested.<br />
<br />
This approach means you are more likely to be successful, and if you really get into DATV, these building blocks can be reused to make even more sophisticated equipment.<br />
<br />
<br />
'''Receiving DATV:'''<br />
<br />
Probably the most repeatable way to do this is to build up a Minitiouner board. Developed by Jean-Pierre Courjaud, F6DZP, this can either be used with his <br />
excellent free MiniTioune Windows software downloadable here: http://www.vivadatv.org/viewforum.php?f=60 <br />
<br />
You can buy the PC board and other "hard-to-get" components from the BATC shop https://batc.org.uk/shop/ - the remainder are standard leaded (no surface mount) components, available from all major suppliers. and can easily be put together in an evening. <br />
<br />
With this you can receive local DATV activity from 2m to 13cm, including digital TV repeaters, and with a satellite dish and LNB, you can watch the activity on QO-100.<br />
<br />
Jean-Pierre's software also comes with a suite of programmes to allow you to test that the board is talking to the software correctly.<br />
<br />
You will then need the normal aerials, filters/pre-amps and/or LNB depending on the band you want to receive. Having said that it is relatively sensitive enough on its own to<br />
be able to receive nearby activity - and probably your local digital TV repeater.<br />
<br />
To find out more, or ask for help, have a look in the Minitioune section of the BATC forum. https://forum.batc.org.uk/viewforum.php?f=105<br />
<br />
<br />
'''DATV transmit:'''<br />
<br />
The BATC Portsdown system is the way go. It is Raspberry Pi 4-based but you can buy a pre-programmed SD card from BATC so there is no programming or computer wizardry at all. This plus a touch screen and a Pluto SDR, which simply plugs in to the Pi's USB socket, will give you a simple to use touch screen DATV transmit system. <br />
<br />
For more details see [[The Portsdown Transmitter|ttps://wiki.batc.org.uk/The_Portsdown_Transmitter]]<br />
<br />
Again if you want more information, or need some help, have a look in the Portsdown section of the BATC forum: https://forum.batc.org.uk/viewforum.php?f=103<br />
<br />
This basic system will give you a full blown DATV transmit system from 50MHz up to 3.4GHz with good picture quality. Again you will need filters and amplifiers for the band of your choice.<br />
<br />
<br />
'''DATV transmit and receive in one box:'''<br />
<br />
Since the release of Portsdown software in autumn 2019 that included the LongMynd receiver you can plug the MiniTiouner USB tuner hardware in to the Portsdown system and it will display the pictures, thereby becoming a full DATV transceiver and replacing the need for a PC. <br />
<br />
The Portsdown 4 software includes everything you need - just make sure you have the latest build - and plug your tuner card in to the Pi's USB port.

<br />
The Portsdown software includes everything you need - just make sure you have the latest Portsdown build - and plug your tuner card in to the Raspberry Pi USB port. See https://wiki.batc.org.uk/Portsdown_4_Pluto for more details.</div>G8XZDhttps://wiki.batc.org.uk/index.php?title=Getting_Started&diff=8593Getting Started2021-07-02T21:43:38Z<p>G8XZD: </p>

<div>Amateur television is a fascinating part of the hobby covering all aspects of video production, editing, transmission and reception of television signals - whether across town or across the world by the geostationary QO-100 satellite.<br />
<br />
One of the aims of the BATC is to help members get on the air and to this end the club has come up with the Portsdown project which is easy enough for most people to successfully build at home. <br />
<br />
The Portsdown is based around the popular Raspberry Pi 4 single board computer, an Adalm Pluto SDR, and controlled by a seven-inch touchscreen. <br />
<br />
Hundreds of these have been built by amateurs around the world and part of its success is down to the club prescribing the key components/design (and you sticking to them...) and following simple build instructions. <br />
<br />
Yes I know radio amateurs (me included) like to tinker and experiment but at this stage it really helps our volunteers help you. That way, if there are any problems, it's easy to offer support via the BATC forum. And if you still can't get it going bring it along to one of our Portsdown clinics which are held at most rallies the BATC attends.<br />
<br />
But if this all sounds overwhelming there's an easy way to "get on the air" using transmitter/receiver modules - if so take a [[5.6 GHz|look at this page]] which shows you how to join in the fun on 5.6GHz for around £20. <br />
<br />
So let's run through the basics:<br />
<br />
<br />
=== ''The best way forward'' ===<br />
<br />
We often get asked how do I start to receive or transmit DATV? <br />
<br />
Like most areas in amateur radio there are lots of ways to do this but let's spend our money (and time) wisely<br />
and put together something tried and tested.<br />
<br />
This approach means you are more likely to be successful, and if you really get into DATV, these building blocks can be reused to make even more sophisticated equipment.<br />
<br />
<br />
'''Receiving DATV'''<br />
<br />
Probably the most repeatable way to do this is to build up a Minitiouner board. Developed by Jean-Pierre Courjaud, F6DZP, this can either be used with his <br />
excellent free MiniTioune Windows software downloadable here: http://www.vivadatv.org/viewforum.php?f=60 <br />
<br />
You can buy the PC board and other "hard-to-get" components from the BATC shop https://batc.org.uk/shop/ - the remainder are standard leaded (no surface mount) components, available from all major suppliers. and can easily be put together in an evening. <br />
<br />
With this you can receive local DATV activity from 2m to 13cm, including digital TV repeaters, and with a satellite dish and LNB, you can watch the activity on QO-100.<br />
<br />
Jean-Pierre's software also comes with a suite of programmes to allow you to test that the board is talking to the software correctly.<br />
<br />
You will then need the normal aerials, filters/pre-amps and/or LNB depending on the band you want to receive. Having said that it is sensitive enough on its own to<br />
be able to receive nearby activity - and probably your local TV repeater.<br />
<br />
To find out more, or ask for help, have a look in the Minitioune section of the BATC forum. https://forum.batc.org.uk/viewforum.php?f=105<br />
<br />
<br />
'''DATV transmit'''<br />
<br />
The BATC Portsdown system is the way go. It is Raspberry Pi 4-based but you can buy a pre-programmed SD card from BATC so there is no programming or computer wizardry at all. This plus a touch screen and a Pluto SDR, which simply plugs in to the Pi's USB socket, will give you a simple to use touch screen DATV transmit system. <br />
<br />
For more details see [[The Portsdown Transmitter|ttps://wiki.batc.org.uk/The_Portsdown_Transmitter]]<br />
<br />
Again if you want more information, or need some help, have a look in the Portsdown section of the BATC forum: https://forum.batc.org.uk/viewforum.php?f=103<br />
<br />
This basic system will give you a full blown DATV transmit system from 50MHz up to 3.4GHz with good picture quality. Again you will need filters and amplifiers for the band of your choice.<br />
<br />
'''DATV transmit and receive in one box'''<br />
<br />
Since the release of Portsdown software in autumn 2019 that included the LongMynd receiver you can plug the MiniTiouner USB tuner hardware in to the Portsdown system and it will display the pictures, thereby becoming a full DATV transceiver and replacing the need for a PC. <br />

This plus a touch screen and a Pluto SDR, which simply plugs in to the Pi's USB socket, will give you a simple to use touch screen DATV transmit system. <br />
<br />
For more details see [[The Portsdown Transmitter|ttps://wiki.batc.org.uk/The_Portsdown_Transmitter]]<br />
<br />
Again if you want more information, or need some help, have a look in the Portsdown section of the BATC forum: https://forum.batc.org.uk/viewforum.php?f=103<br />
<br />
This basic system will give you a full blown DATV transmit system from 50MHz up to 3.4GHz with good picture quality. Again you will need filters and amplifiers for the band of your choice.<br />
<br />
'''DATV transmit and receive in one box'''<br />
<br />
Since the release of Portsdown software in autumn 2019 that included the LongMynd receiver you can plug the MiniTiouner USB tuner hardware in to the Portsdown system and it will display the pictures, thereby becoming a full DATV transceiver and replacing the need for a PC. <br />
<br />
The Portsdown software includes everything you need - just make sure you have the latest Portsdown build - and plug your tuner card in to the Raspberry Pi USB port. See https://wiki.batc.org.uk/Portsdown_4_Pluto for more details.</div>G8XZDhttps://wiki.batc.org.uk/index.php?title=Getting_Started&diff=8587Getting Started2021-07-02T21:37:19Z<p>G8XZD: </p>

<div>Amateur television is a fascinating part of the hobby covering all aspects of video production, editing, transmission and reception of television signals - whether across town or across the world by the geostationary QO-100 satellite.<br />
<br />
One of the aims of the BATC is to help members get on the air and to this end the club has come up with the Portsdown project which is easy enough for most people to successfully build at home. <br />
<br />
The Portsdown is based around the popular Raspberry Pi 4 single board computer, an Adalm Pluto SDR, and controlled by a seven-inch touchscreen. <br />
<br />
Hundreds of these have been built by amateurs around the world and part of its success is down to the club prescribing the key components/design (and you sticking to them...) and following simple build instructions. <br />
<br />
Yes I know radio amateurs (me included) like to tinker and experiment but at this stage it really helps our volunteers help you. That way, if there are any problems, it's easy to offer support via the BATC forum. And if you still can't get it going bring it along to one of our Portsdown clinics which are held at most rallies the BATC attends.<br />
<br />
But if this all sounds overwhelming there's an easy way to "get on the air" using transmitter/receiver modules - if so take a [[5.6 GHz|look at this page]] which shows you how to join in the fun on 5.6GHz for around £20. <br />
<br />
So let's run through the basics:<br />
<br />
==2021 Digital ATV primer==<br />
<br />
We often get asked how do I start to receive or transmit DATV? <br />
<br />
Like most areas in amateur radio there are lots of ways to do this but let's spend our money (and time) wisely<br />
and put together something tried and tested.<br />
<br />
This approach means you are more likely to be successful, and if you really get into DATV, these building blocks can be reused to make even more sophisticated equipment.<br />
<br />
'''Receiving DATV'''<br />
<br />
Probably the most repeatable way to do this is to build up a Minitiouner board. Developed by Jean-Pierre Courjaud, F6DZP, this can either be used with his <br />
excellent free MiniTioune Windows software downloadable here: http://www.vivadatv.org/viewforum.php?f=60 <br />
<br />
You can buy the PC board and other "hard-to-get" components from the BATC shop https://batc.org.uk/shop/ - the remainder are standard leaded (no surface mount) components, available from all major suppliers. and can easily be put together in an evening. <br />
<br />
With this you can receive local DATV activity from 2m to 13cm, including digital TV repeaters, and with a satellite dish and LNB, you can watch the activity on QO-100.<br />
<br />
Jean-Pierre's software also comes with a suite of programmes to allow you to test that the board is talking to the software correctly.<br />
<br />
You will then need the normal aerials, filters/pre-amps and/or LNB depending on the band you want to receive. Having said that it is sensitive enough on its own to<br />
be able to receive nearby activity - and probably your local TV repeater.<br />
<br />

<div>'''You're probably here because you want to know more about ATV so to help you get to grips with the basics the BATC has put together a series of "getting started" guides.'''<br />
<br />
Amateur television is a fascinating part of the hobby covering all aspects of video production, editing, transmission and reception of television signals - whether across town or across the world by the geostationary QO-100 satellite.<br />
<br />
One of the aims of the BATC is to help members get on the air and to this end the club has come up with the Portsdown project which is easy enough for most people to successfully build at home. <br />
<br />
It is based around the popular Raspberry Pi 4 single board computer, an Adalm Pluto SDR, and controlled by a seven-inch touchscreen.<br />
<br />
Hundreds of these have been built by amateurs around the world and part of its success is down to the club prescribing the key components/design (and you sticking to them...) and following simple build instructions.<br />
<br />
Yes I know radio amateurs (me included) like to tinker and experiment but at this stage it really helps our volunteers help you.<br />
<br />
That way, if there are any problems, it's easy to offer support via the BATC forum. And if you still can't get it going bring it along to one of our Portsdown clinics which are held at most rallies the BATC attends.<br />
<br />
But if this all sounds overwhelming there's an easy way to "get on the air" using transmitter/receiver modules - if so take a [[5.6 GHz|look at this page]] which shows you how to join in the fun on 5.6GHz for around £20. <br />
<br />
So let's run through the basics:<br />
<br />
==2021 Digital ATV primer==<br />
<br />
We often get asked how do I start to receive or transmit Digital Amateur TV - below is an answer a BATC member gave to this question on the BATC forum.<br />
<br />
'''Receiving DATV'''<br />
<br />
The only real show in town and the most flexible, is the PC based MiniTiouner system with a USB tuner card. The reason for this is that it tunes from 143 MHz to 2450 MHz so covers all the bands from 146 > 13cms and with a standard LNB can be used to receive Oscar 100 signals. It also can receive all the Symbol Rates (SR) or bandwidths from 33Ks (the lowest RB-TV you will find) right up to 27,500 as used on Freeview etc.<br />
<br />
The system consists of the USB tuner card hardware which you build (no Surface Mount!) - the 4 hard to get components are from the BATC shop and the software is free to download - total cost = ~£80 depending upon the case you use.<br />
<br />
You will then need the normal filters / pre-amps annd / or LNB depending on the band you want to receive but it will be all you will ever need! <br />
<br />
See [[MiniTioune|https://wiki.batc.org.uk/MiniTioune]] for more details.<br />
<br />
Yes, there are are a couple of Set Top Boxes that will receive some reduced bandwidth signals but you will need freq converters etc. There is also a PC software program called SDRAngel which you can use with the cheap £10 RTL dongle. In my opinon both of these options require a lot of faffing about and you cannot quarantee results.<br />
<br />
'''DATV transmit'''<br />
<br />
The BATC Portsdown system is the way go. Yes it is Raspberry Pi based but you can buy a pre-programmed SD card from BATC so there is no programming or computer wizzardry at all. This plus a touch screen and a LimeSDR Mini, which simply plugs in to the Rpi USB socket, will give you a simple to use touch screen DATV transmit system. <br />
<br />
This basic system will cost ~ £250 ( less than a dual band FM rig!) and give you a full blown DATV transmit system from 50MHz up to 3.4GHz with good picture quality. There is some limitations on symbol rates - with the Lime SDRmini you can only transmit up to 1Ms . Again you will need filters and amplifiers for the band of your choice....<br />
<br />
For more details see [[Portsdown_2019|https://wiki.batc.org.uk/Portsdown_2019]]<br />
<br />
'''DATV transmit and receive in one box'''<br />
<br />
Since the release of Portsdown software in autumn 2019 that included the LongMynd receiver you can plug the MiniTiouner USB tuner hardware in to the Portsdown system and it will display the pictures, thereby becoming a full DATV transceiver and replacing the need for a PC. <br />
<br />
The Portsdown software includes everything you need - just make sure you have the latest Portsdown build - and plug your tuner card in to the Raspberry Pi USB port. See https://wiki.batc.org.uk/The_Portsdown_Receiver for more details.<br />
<br />
==Getting Started - the guides==<br />
<br />
Below are a series of guides which have been written by BATC members - unfortunately our hobby moves at a rapid pace so that guides written only 3 years ago are now out of date!<br />
<br />
A good place to start is by reading the [[Media:GSATV2016.pdf|Getting Started in ATV leaflet]] also available as an [[Media:Getting started with ATV.pdf|article extract]] from CQ-TV, our quarterly newsletter: <br />
<br />
Or take a look at this [[Media:Getting started Feb 2018.pdf|introduction to ATV PowerPoint presentation]]<br />

<div><br />
It is very easy (and low cost) to get on the air on 5.6GHz (the 6 cm amateur band) using the cheap modules intended to transmit “First Person Video” (FPV) back from drones to their operators.<br />
<br />
These units can be used without any modifications to get on air, and with a simple wifi plate or dish antennae and a clear line of sight path, can be used to can send pictures to stations using the same equipment over 50 Kms away.<br />
<br />
[[File:5.6 GHz Orientation Small.jpg|500px|center]]<br />
<br />
<br />
==Frequency choice==<br />
<br />
The UK amateur band plan is shown on the RSGB website here: https://thersgb.org/services/bandplans/html/rsgb_band_plan_2017.htm<br />
<br />
[[File:bandplan.JPG|800px]]<br />
<br />
GB3KM has a licenced input on 5665 MHz and this has been chosen as the primary ATV operating frequency.<br />
<br />
The FPV equipment receive and transmit frequencies are set using DIP switches, and most tune to this frequency but care needs to be taken when selecting equipment to make sure it does cover this frequency. Example channel tables are shown at the bottom of this page.<br />
<br />
==Equipment== <br />
<br />
The FPV units are widely advertised on eBay and other sites with titles similar to “Tarot 5.8G 600MW Telemetry TX/RX Combo for FPV Image Transmission TL300N” and are available at reasonable prices. The typical units are very small but have reasonable FM-TV performance with a quoted spec of 600 milliwatts out and receiver sensitivity of -80 dBm. Amplifiers are available to raise the output power to 2 watts or more.<br />
<br />
[[File:Tairot 1.jpg|400px]]<br />
<br />
Be aware - we have found that on some rx units, the video out is on the Red phono lead and not the expected Yellow lead!<br />
<br />
===Mounting the equipment===<br />
Due to the very high losses in co-ax cable at 5.6GHz it is recommended that you mount the units very close to the antennae and run long 12v DC and Audio and video cables back down the cable to the shack or operating position. <br />
<br />
Also whilst these units are very small they do run very hot in operation and it is suggested you provide a good heatsink for both Tx and Rx - mounting them in a diecast box on the back of the antennae is ideal.<br />
<br />
[[File:GKQ 5.6v2.JPG|600px]]<br />
<br />
<br />
Detail of G8GKQ transceiver setup is shown here (receiver unit on left & transmitter with fan on the right)<br />
<br />
===Transmit amplifiers===<br />
<br />
Whilst the basic units work very well and have been used to transmit over 60 Kms, power amplifiers to boost the 600mw transmitter signal to 2 - 4 watts are available from several suppliers on ebay and other sites and will significantly increase the distance the units will work over. These should be connected after the transmit unit but before any antennae change over relay and remember that his will increase the volt drop on any long 12v cable feeding the transmitter at masthead. <br />
<br />
[[File:56PA.jpg|400px]]<br />
<br />
==Antenna change over relays==<br />
<br />
The FPV equipment comes as separate Tx and Rx units. In order to operate on a single aerial, you will need an antennae changeover relay, however the losses at 5.6GHz can be significant and care must be taken when wiring up the units to ensure RF cables are of good quality and kept to a minimum length - semi rigid cable with SMA connectors are ideal. <br />
<br />
PL259 and even BNC connectors are very lossy at 5.6GHz and should not be used but the surplus SMA relays often available at rallys are ideal for 5.6 GHz. <br />
<br />
See [[Antennae changeover relays|this wiki page]] for more details on suitable relays, 24 volt operation and 4 port or transfer relays.<br />
<br />
If no suitable relay is available It may be cheaper to use a separate antenna for receive and transmit as shown in the picture below - note the Tx and Rx units are mounted directly on the back of the flat panel antennaes.<br />
<br />
[[File:562.jpg|300px]]<br />
<br />
===Reverse SMA=== <br />
<br />
Be aware that all the 5.6GHz FPV units are reverse SMA (like wifi equipment) and all low loss cables, unless bought specifically for the purpose, and suplus SMA relays are almost certain to be standard SMA connectors and will not fit. Adapters from reverse to standard SMA are available on ebay or other suppliers.<br />
<br />
==Antennas==<br />
<br />
As 5.8GHz is also used by broadband wireless networks, there is a wide choice of antennae available for use on 5.6GHz ATV. This can range from flat plates to wire mesh dishes as seen in the above pictures.<br />
<br />
It is also possible to use a satellite mini dish with a suitable feed such as a wave guide horn to the design by G4NNS.<br />
<br />
The picture shows a Sky mini dish fed with a WA5VJB log period PCB feed (available from G4DDK).<br />
<br />
[[File:56 dish feed.JPG|400px]]<br />
<br />
<br />
Horizontal polarity has been chosen as the standard and dishes of this size typically have a beam width of 4-8 degrees.<br />
<br />
==Video equipment==<br />
<br />
===Rx===<br />
The receiver output will need to be directly connected to a composite video input monitor to view the received the signal - normally on a yellow phono or RCA connector. <br />
<br />
====Video squelch defeat==== <br />
<br />
Beware of using modern flat screen monitors which have a video squelch which will not display noisy signals and just give a blue screen until they get a strong video signal.<br />
<br />
There are a number of circuits around to defeat the squelch:<br />
<br />
* Syncsmurf by PE1RQM - kits are available details on the [https://translate.google.com/translate?hl=auto&sl=auto&tl=en-US&u=https%3A%2F%2Fwww.pe1rqm.nl%2Fsyncsmurf2%2F webpage here].<br />
* Video sync processor – CQ-TV 129<br />
<br />
Or any video sync processor may be useable.<br />
<br />
[[File:ACE.jpg|300px]]<br />
<br />
===Tx===<br />
An old camcorder with a yellow phono video out socket is an ideal video and audio source for the transmitter but don't forget you will need to display your call sign to remain legal. This can be a video generator, a jpeg card reader with video out, the Portsdown system with video out or a piece of card with your call sign scribbled on it!<br />
<br />
==On the air==<br />
<br />
Using dish aerials of 30 – 60 cm, line of sight ranges of 80 km can easily be achieved. <br />
<br />
P5 (noise free) FM ATV pictures have been exchanged over an 138km path using the equipment described on this page - the picture below shows G4CPE/p on Dunstable Downs being received at the Ridgeway near Didcot over a slightly obstructed 66Km path.<br />

==More information==<br />
<br />
Dave G8GKQ did a presentation at the BATC annual convention CAT17 in September 2017 on getting started on 5.6 GHz ATV.<br />
*The presentation is available here https://wiki.batc.tv/images/9/94/CAT17_Portsdown_Update.pdf<br />
*The video of the session is available on the BATC youtube channel here https://www.youtube.com/watch?v=XJzGNsGmE9Y<br />
<br />
There is a thread running on the BATC forum where the ATV community are exchanging ideas and also posting results of the latest on air tests. http://www.batc.org.uk/forum/viewtopic.php?f=2&t=5026<br />
<br />
==Technical information==<br />
<br />
===SM201R===<br />
The large rx chip in most units has got the part number removed, however it appears that a lot of receivers use the SM201R module. The spec and pinout are shown below but notice the frequency range of this particular unit does not seem to cover 5665MHz so make sure the one you buy does! <br />
<br />
[[File:sm201r 3.JPG|300px]] [[File:sm201r 2.jpg|500px]]<br />
<br />
<br />
[[File:sm201r 1.JPG|500px]]<br />
<br />
===S meter output===<br />
<br />
Looking at the above table it appears that the RSSI is available on pin 17 of the SM201R and could potentially be used for a signal strength meter to help align the antennas when setting up a QSO.<br />
<br />
It also appears that the SM201R uses a 480MHz IF (same as the Comtech) and potentially could be modified with narrower filters to improve RF performance.<br />
<br />
====Tx and Rx perfomance====<br />
<br />
Initial measurements suggest the Tx bandwidth is 25 - 30 MHz.<br />
<br />
[[File:5.6GHz spectrum.jpg|500px]]<br />
<br />
This accounts for the quoted Rx sensitivity at -80dBm which may be improved by an LNA but will ultimately be limited by the Rx IF bandwidth.<br />
<br />
===Channel Listings===<br />
<br />
As mentioned above, the channels settings vary from manufacturer to manufacturer. This table is taken from the Tarot data sheet which uses the SM201R module but does include 5665MHz:<br />
<br />
