Stations transmit digital pictures on 2m, 70cm and 2m and receive television pictures using the 23cm band.
 
Stations using GB3NQ may use relatively cheap 23cm transmitters and receivers using one of the Portsdown or Minitioune/Ryde projects available from the BATC (British Amateur Television Club) or suitable HD DVBS-2 satellite set top boxes -check suitability before purchase. https://batc.org.uk/
 
The input frequency is 146.5 Mhz, 437Mhz and 1249 MHz and H265 HD output on 1316 MHz with a SR 2000k and an FEC 4/5 DVBS-2.There is also a second output on 1318MHz with a SR 333k. Although GB3NQ has audio through, stations often use talkback on the 2 metre frequency of 144.750 MHz or via GB3NC repeater on 145.725Mhz.
 
The new digital repeater electronics were constructed by Paul G6MNJ and Keith G0KTD using British Amateur Television Clubs Portsdown transmitter and 3 Ryde receivers
all based around a Raspberry Pi 4. Further work is progressing - updating the control logic to use a Pico, new 8 way HDMI switch and a LinkPi encoder
 
A 150 watt power amplifier is driven by a 18 watt pre amplifier, both run considerably under power to remain linear - a must for digital ATV.
 
GB3NQ runs in Beacon mode between Mid day and 9Pm when it plays out a video for 30 minutes. When running between 10am and 10pm (10am to 10pm weekends and midday to 10pm in the week) it may be accessed at any time with a s valid digital television signal on 2m, 70cm or 23cm.This would be a symbol rate of 333Ksymbols/s on 2m or on 70cm and 23cm symbol rates of 333, 1000 or 2000 Ks/s.
 
The repeater transmits H265 HD on 1316MHz 2000Ks/s FEC 4/5 DVBS-2.
 
GB3NQ was originally constructed by two local amateurs. Maurice G3WKF and John G0VDU. Maurice, a mechanical engineer, made the high quality filters for the input and output of the repeater and also the 4 faced lantern antennas required for the transmitter and receiver which are still in use today.

Using the Ryde software alongside Portsdown

2024-11-06T15:53:43Z

G8LCE:

It is possible to load the Ryde software alongside the Portsdown 4 Software. This facility is primarily intended to support the use of web-controlled Portsdowns with no touchscreens that are driving an HDMI display, but can also be used to display the received picture on the touchscreen. The Ryde can then be tuned for QO-100 using M0DTS's excellent QuickTune software on a Windows PC.

To set up the Ryde software, go to Menu 2, File Menu, and select "Install Ryde RX". The install will take 5 to 10 minutes and the Portsdown will reboot back to Menu 1 when the install is complete.

To start the Ryde software, connect a tuner and select Menu 2, "Ryde Receiver". The Ryde software will run until the touchscrren (or web control) is touched and then Portsdown software will restart.

Control of the Ryde software will require the use of QuickTune or a similar application. An IR sensor could be installed and a remote control used, or the /home/pi/ryde/config.yaml file could be manually edited to achieve the desired start-up settings.

The audio output destination can be selected from Menu 3, and is set to the same as the internal Portsdown receiver.

The video output resolution will be 800*480 @ 60fps like the Portsdown screen.

If using the Portsdown 'Ryde' and you need to set the frequency etc. manually use Putty to log on to the RPi.
Then

sudo nano /home/pi/ryde/config.yaml

Select the preset you want to start with (note they are labelled 01,02,03 etc.) and set up the parameters you want.
Then move further down to where it says 'default: *preset01'and alter the 01 to the preset number you want.
Write Out and Exit then Menu and select Reboot.

You can also edit the audio level if you look further down the config:

audio:
muteOnStartup: False
volumeOnStartup: 60
volumeStep: 10
enableMenu: False

Note that MAX = 99
