<hr />
<div>Since the demise of Flash at the end of 2020 you will find your standard web browser has about 15 seconds delay on a streamed repeater channel. <br />
<br />
However, a program called Video Lan Client (VLC) enables you to watch a typical repeater stream using Flash with ~ 2 seconds delay.<br />
<br />
==Easy to use BATC streamer viewer==<br />
<br />
Using VLC can be a bit "techie" and so John G7JTT has written a small program that saves having to manually configure VLC.<br />
<br />
* Download and install VLC https://www.videolan.org/vlc/index.en-GB.html - <br />
<br />
* Download the following file [[:File:BATCStreamViewerv0.2.zip]]<br />
<br />
* Extract it and then run "BATC-StreamerViewer.exe"<br />
<br />
* Select the channel you wish to watch and press OK.<br />
<br />
If you tick the "stay on top" box you can open up your web browser to the same streaming page and then drag the viewer on top of the normal video window. When you use the chat the viewer will remain visible. Don't forget to turn the sound down on the web browser or you will get a 15-second echo!<br />
<br />
[[File:Streamviewr 2.jpg|500px]]<br />
<br />
The picture shows streamviewer imposed on top of a standard web browser page.<br />
<br />
==Multi channel stream viewer==<br />
<br />
John has also written a multi channel viewer which can be used to view up to 4 streams at once. It can also be used to view the UDP output from MiniTiouner or Ryde.<br />
<br />
It can be downloaded here: [[:File:VLC-Quadv0.3..zip]]<br />
<br />
[[File:quad viewer.png|500px]]<br />
<br />
==Manually configuring VLC==<br />
<br />
Follow these instructions:<br />
<br />
Download VLC https://www.videolan.org/vlc/index.en-GB.html - <br />
<br />
Go to "Media" > "open network stream": or press CTRL-N <br />
<br />
[[File:VLC stream channel.JPG|400px]]<br />
<br />
Enter the following into the network URL box:<br />
<br />
'''rtmp://rtmp.batc.org.uk/live/xxxxx''' - where xxxx is the name of the stream you want to watch.<br />
<br />
Press play.<br />
<br />
==To create a desktop shortcut in Windows==<br />
<br />
Firstly create a shortcut to VLC on your desktop, then right click on the shortcut and add the path to your favourite channel at the of the line in the "Target" window. <br />
<br />
"C:\Program Files\VideoLAN\VLC64\vlc.exe" rtmp://rtmp.batc.org.uk/live/gb3sq<br />
<br />
by adding -f it will open in full screen <br />
<br />
"C:\Program Files\VideoLAN\VLC64\vlc.exe" -f rtmp://rtmp.batc.org.uk/live/gb3sq<br />
<br />
You can also change the icon to differentiate between streams, here are a few I use<br />

<div>[[File:5.6 GHz Orientation Small.jpg|300px|center]]<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. These units can be used without any modifications to get on air, and with simple WiFi plate or dish antennas (and a clear line of sight path) can be used to send pictures to stations using the same equipment over paths in excess of 50km.<br />
<br />
M0KPW has an excellent website describing his 5.6GHz system http://www.5-6ghz-atv.co.uk/<br />
<br />
==Frequency choice==<br />
<br />
The overall UK amateur band plan is shown on the RSGB website here: https://rsgb.org/main/operating/band-plans/. As the UK amateur frequency allocation for 5 GHz is not contiguous spectrum, the RSGB has some [https://rsgb.org/main/operating/band-plans/microwaves/5-7-and-10ghz/ useful guidance] which is adapted below with arrow markers:-<br />
<br />
<br />
[[File:bandplan.JPG|800px]]<br />
<br />
GB3KM has a licensed input on 5665 MHz and this has been chosen as the primary ATV operating frequency. Audio WB-FM operators have been using 5825 and 5840 MHz. 5825 MHz is too close to the band edge for ATV, and 5840 MHz is marginal. So 5665 is the general ATV preference<br />
<br />
The FPV equipment receive and transmit frequencies are set using DIP switches, and most tune to 5665 MHz &ndash; 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 transmitter spec of 600mW output and receiver sensitivity of -80dBm. Amplifiers are available to raise the output power to 2 watts or more.<br />
<br />
[[File:Tairot 1.jpg|400px]]<br />
<br />
Be aware &ndash; we have found that on some receiver units, the video output is on the Red phono lead and not the expected Yellow lead!<br />
<br />
Some other users' stations are described here [[5.6 GHz Equipment Examples]].<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 antennas and run long 12V dc, audio and video cables back down to the shack or operating position. <br />
<br />
Be aware also, that whilst these units are very small they do run very hot in operation, and it is suggested that you provide a good heatsink for both Tx and Rx &ndash; mounting them in a diecast box on the back of their respective antennas is ideal.<br />
<br />
[[File:GKQ 5.6v2.JPG|600px]]<br />
<br />
<br />
Details of G8GKQ's 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 paths of 60km, power amplifiers to boost the 600mW transmitter signal to 2&mdash;4 Watts are available from several suppliers on eBay and other sites, and will significantly increase the path length that the units will work over. These amplifiers should be connected after the transmit unit, but before any antenna change over relay(s) &ndash; and remember that his will increase the volt drop on any long 12V cable feeding the transmitter at the masthead.<br />
<br />
Be warned!! Several users have found these PAs to be "fragile", so you should always make sure that the antenna is connected &ndash; and all connectors done up tight &ndash; before applying dc or RF power. We are investigating whether they can be made more reliable by reducing the volts / input drive.<br />
<br />
<br />
[[File:56PA.jpg|200px]]<br />
<br />
==Antenna changeover relays==<br />
<br />
The FPV equipment comes as separate Tx and Rx units. In order to operate on a single antenna, you will need an antenna changeover relay. Note, however, that 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 &ndash; semi-rigid cables fitted 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 separate antennas for receive and transmit as shown in the picture below &ndash; note the Tx and Rx units are mounted directly on the back of the flat panel antennas.<br />
<br />
[[File:562.jpg|200px]]<br />
<br />
===Reverse SMA=== <br />
<br />
Be aware that all the 5.6GHz FPV units use "reverse SMA" connectors (as used on WiFi equipment) and that all low-loss cables (unless bought specifically for the purpose) and surplus SMA relays will almost certainly have standard SMA connectors &ndash; which will not fit. Adapters from reverse to standard SMA are available on eBay or other suppliers &ndash; search for "RP-SMA to SMA adaptor" or similar wording.<br />
<br />
==Antennas==<br />
<br />
As 5.8GHz is used by broadband wireless networks, there is a wide choice of antennas available for use on 5.6GHz ATV. These can range from flat plates/panels to wire mesh (grid) dishes, as seen in the above pictures.<br />
<br />
<br />
Horizontal polarisation has been chosen as the standard (waveguide feeds needs to have the long dimension of the aperture &ndash; and/or horn &ndash; vertically oriented when feeding dishes)<br />
<br />
=== Satellite dishes ===<br />
<br />
It is also possible to use a satellite mini dish with a suitable feed, such as a waveguide/horn to the design by G4NNS &ndash; see here for construction details: http://myweb.tiscali.co.uk/g4nns/FeedHorn.html<br />
<br />
The picture shows a Sky mini dish fed with a WA5VJB log-periodic PCB feed http://www.wa5vjb.com/products1.html &ndash; these are available in the UK from G4DDK. http://www.g4ddk.com/Prices.html<br />
<br />
Dishes of this size typically have a beam width of 4&mdash;8 degrees.<br />
<br />
[[File:56 dish feed.JPG|400px]]<br />
<br />
<br />
M1BKF found a very interesting 5.6GHz feed for standard f/d ratio satellite dishes; it contains what looks like a PCB yagi, and is available from:<br />
<br />

<br />
<br />
=== DIY BiQuad antennae ===<br />
<br />
This web page http://buildyourownantenna.blogspot.co.uk/2014/07/double-biquad-sector-antenna-for-5-ghz-wifi.html has a well engineered double BiQuad antenna with a quoted 13dBi gain.<br />
<br />
Note in the picture G8JAN has directly connected the Tx module to the antenna to avoid co-ax losses.<br />
<br />
[[File:feed.jpg|400px]]<br />
<br />
==Video equipment - Rx==<br />
The receiver output will need to be directly connected to a monitor with a composite video input to view the received the signal &ndash; 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 &ndash; these 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 and also improve the readability of the signal.<br />
<br />
===Syncsmurf by PE1RQM=== &ndash; 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 />
<br />
[[File:syncsmurf1.jpg|200px]]<br />
<br />
Results are very impressive:<br />
<br />
[[File:syncsmurf2.jpg|400px]]<br />
<br />
===eachine FPV recorder===<br />
<br />
Several people have reported that they are using these devices, available from various sites, and as well as defeating the monitor blue screen by inserting syncs on noise they have a single push button record facility. They record to an SD card which can be removed and the files viewed on a PC; users report that you need to use a good quality SD card, and that they have had problems with Kingston branded cards &ndash; Sandisk are preferred. <br />
The one issue with them is that they crop PAL signals removing 15% at the top and bottom of the picture. This is a hardware issue, so no amount of software updates will solve it. The workaround is that the unit will not crop PAL pictures if the video input is present when the unit is powered up. NTSC pictures are not affected<br />
<br />
[[File:emachine dvr.JPG|300px]]<br />
<br />
===Video sync processor===<br />
<br />
[[File:cqtv 129.jpg|300px]]<br />
<br />
<br />
Or any video sync processor may be usable such as the Advanced Converter Enhancer used by many stations on 23cms FM TV transmissions.<br />
<br />
[[File:ACE.jpg|300px]]<br />
<br />
==Receive Pre-amplifiers==<br />
<br />
The basic drone recievers are fairly sensitive. However the perfomance can be improved by using a pre-amp before the unit but is also recommended that a bandpass filter included on the pre-amp output.<br />
<br />
A cheap but high performance pre-amp can be made using the surplus LNA PCBs available from Franco in Italy https://www.rf-microwave.com/en/nbp/nmp/10-ghz-amplifier-24ghz-doubler/su-02/ <br />
<br />
These boards are fantastic value for money and can be used to make 10GHz pre-amps or the devices can be used to replace blown devices in most DB6NT transverters.<br />
<br />
The following document shows the simple mods required to make a 5.6GHz pre-amp: <br />
<br />
[[File:5.6GHz pre-amp.JPG|600px]]<br />
<br />
The unit requires 5volts and minus volts for bias which can either be generated using the circuit on the main Franco PCB or the following circuit:<br />
<br />
[[File:supply.jpg|600px]]<br />
<br />
==Video equipment - Tx==<br />
An old camcorder with a yellow phono "video out" socket is an ideal video and audio source for the transmitter.<br />
<br />
Don't forget that you will need to display your call sign to remain legal. This can be a video generator, a .jpg card reader with video out, or a piece of card with your call sign scribbled on it!<br />
<br />
===Media card reader===<br />
<br />
A simple way to generate test patterns is to use a media card reader loaded with .jpg files &ndash; these are available on several sites, just search for "SD card media AV player" &ndash; but make sure you get one which outputs PAL video.<br />
<br />
[[File:av player.JPG|200px]]<br />
<br />
===PicDream===<br />
The PicDream project uses a single PIC chip and a 4MHz crystal to generate a black and white test pattern &ndash; simple but effective &ndash; the original project was described in CQ-TV 180 and re-printed in CQ-TV 247.<br />
<br />
[[File:Picdream 247.JPG|400px]]<br />
<br />
The PIC code is available for download here: batc.org.uk/cq-tv/software/picdream.zip<br />
<br />
===PicDream II===<br />
<br />
[[File:picdream2.jpg|400px]]<br />
<br />
<br />
The PicDream II project uses a PIC chip and an AD724 PAL ecnoder chip to generate a colour test pattern with moving insets. The text and colours on the test pattern can be set through it's serial link.<br />
<br />
Further information is at https://github.com/F1CJN/PICDREAM-II<br />
<br />
===Raspberry Pi - PA3CHM image generator===<br />
<br />
CQ-TV 247 published details of a simple RPi-based test card generator by Ernest PA3CHM.<br />
<br />
[[File:PA3chm.JPG|400px]]<br />
<br />
Full details are on his website: http://www.pa3hcm.nl/?p=248<br />
<br />
===Raspberry Pi - Portsdown patterns===<br />
The BATC Portsdown project can be configured to deliver composite video and audio out from the RPi multi-jack plug. <br />
<br />
[[File:GKQ July 2017 (Small).JPG|400px]]<br />
<br />
This can be test patterns, RPi desktop, or the Portsdown camera and microphone &ndash; [[Analog Video Output|see this wiki page for more details]] making the RPi the only piece of video/audio equipment you need to drive the 5.6GHz transmitter.<br />
<br />
===Stand alone Raspberry Pi animated test card generator===<br />
This is the stand alone version of the animated test card generator that is part of the Portsdown software <br />
[[RPi Test Card| - <u>see this wiki page for more details</u>]]<br />
<br />
==On the air==<br />
<br />
Using dish aerials of 30&mdash;60cm, line of sight ranges of 80km can easily be achieved. <br />
<br />
P5 (noise free) FM ATV pictures have been exchanged over a 138km path using the equipment described on this page &ndash; the picture below shows G4CPE/P on Dunstable Downs being received at the Ridgeway, near Didcot, over a slightly obstructed 66km path.<br />
<br />

Dunkery Beacon near Minehead, to Cleeve Common near Cheltenham.<br />
The picture shows G8GTZ/P received by G8GKQ/P over the 138km path.<br />
<br />
[[File:snap5 small.jpg|400px]]<br />
<br />
<br />
2018-04-21: The UK "record" for a contact using standard FPV units was increased to 153km between GW3NWR/P at Bylchau, North Wales to M0KPW/P and G0HIK/P at the Kirkstone Pass Inn, Cumbria.<br />
<br />
This has since been surpassed.<br />
<br />
==FM voice only==<br />
<br />
Several stations in the Gloucester and Bolton area are using these units for wideband FM voice only. This is achieved by simply putting high level (1V peak-peak) audio on the yellow video TX phono input &ndash; this modulates the main high level carrier with audio rather than video (the two audio phono connectors &ndash; red and white &ndash; can be ignored). On RX, the yellow phono connector of the receiver is simply connected to a line level input of an audio amplifier. <br />
<br />
It is done this way because the two audio subcarriers transmitted by the unit are at a level 20dB lower than that of the main (video)carrier. However, as it is using the same bandwidth Rx and Tx system, performance will be no better than FM video &ndash; ideally the 480MHz RX IF would be tapped off in to an SDR or narrow band receiver to give significantly enhanced (+20db?) narrow band performance.<br />
<br />
==Activity hot spots==<br />
<br />
There is a Google map showing approximate locations of stations thought to be active on 5.6GHz FM &ndash; if you are on 5.6GHz, you can add or edit your station: https://www.google.com/maps/d/u/0/edit?mid=1e4keFSFWy6wLUQNF3IT3n6h90eU&ll=52.39133141509076%2C-1.8917942000000494&z=7<br />

<br />
==Technical information==<br />
<br />
===SM201R===<br />
The large RX chip in most units has had 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 2.jpg|500px]] [[File:sm201r 3.JPG|200px]]<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&mdash;30MHz.<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 channel 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 />
[[File:Tarot_Channels.jpg|603px]]<br />

==Improvements to Commercial Units==<br />
<br />
In CQ-TV 260, Achille I2GLI described improvements and additions to the Mateksys VTX-HV drone transmitter to make a high quality 18 watt output 5.6 GHz FM transmitter. One of the improvements was to replace the video and sound baseband circuitry. The published circuit diagram in online CQ-TV was a little unclear (although the printed version is good). The circuit diagram is reproduced below.<br />
