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.

My QO-100 DATV setup is very simple as you can see from the short explanation below.

The setup is very simple and easy to achieve and I hope that this may lead you to have ago, the Logitech C920 Webcam is my main video source in the shack


This is connected via USB to my PC which is based around a high end Intel I5 CPU,we also have 8Gb of Ram and an SSD drive and the Operating system is Windows 11.

This PC also has an Nvidia GT660 graphics card with 6Gb of Ram installed, this is very important as all of the video processing and encoding to H264 and H265 formats is all done by the graphics card.

I then use the OBS software to control my video sources add text and transition between scenes using this software


The output from OBS is sent to the F1EJP FreeStreamCoder software.


This is where all of the things like frame rate, Audio and Symbol rates are selected.

The output from the FreeStreamCoder software is them sent via a network IP connection to my Adalm-Pluto


This will generate the RF output with is at a very low level. The output from the Pluto is increased by using the Amsat UK Filtered S Band Driver Amplifier Kit


The output from this Amsat UK Filtered S Band Driver unit is connected to a surplus PA which I get from eBay


The output from this amp is connected via LDF4-50 co-ax to a POTTY patch feed.


One receive I have an LNB fitted on the 22mm Pipe from the POTTY

This mounted at the focal point of in my case a 1.2m prime focus dish.

I use standard satellite TV cable to bring the signal back and this is feed into a MiniTiouner DATV receiver.


The MiniTiouner is connected to my Ryde DATV receiver.
