Decided to test the limits of the Ryde rx on GB3FT and found that it can handle 32APSK FEC 9/10 at 1MS no problem at all - given a strong enough signal.
At the other extreme using only 30mW at 333kS and FEC 1/4 I was able to access FT and this over a none line of sight 10 mile path.
Very pleased with Ryde rx
Re: Very pleased with Ryde rx
It seems to me after testing the Ryde on 1316MHz B input and 437MHz A input, scanning through both at 125k, 333k, 1M and 2M SR that the main problem is not the Ryde receiver but the difficulty in producing the signals to test it! The Ryde receives all I can make work. The Portsdown 4 does the Mpeg-2 DVB DVB-S2 H264 etc. while a Pluto and DATV Express software does the lower SR and H265. That is when the computer needs to have a bit of power due to the processing needed. I use a test video with different testcards and video clips with stereo audio played from vMix HD basic. That shows the limitations of the coding system in the transmitter. Static testcards are easy!
I still have a wish list for extra facilities that would be nice but when I look at the little Raspberry Pi 4 sitting there in it's heatsink connected to the Minitiouner V2 and it does all this, I think I'll just thank the development team and keep quiet!

Re: Very pleased with Ryde rx
And another thing!
I have just tried the development version of the software and my remote has been added.
I am very impressed by the way that works with the menus. You can forget about ssh and set up a multi frequency, multi SR scan just from there!
Another well done to the team.

Set the scan time down to two seconds and it works! This is between 437MHz and 1316MHz 333K SR and 2000K SR so max scan time should be 8 seconds between LOS and receiving .
See test video here : opps wrong video - don't know where that came from! here the right link https://vimeo.com/481217557
So this shows my local testcard on 437MHz from a Portsdown 4. You can see how long it takes to go from LOS until it scans through and finds the TX again. I just TX off then on to do that. Then the last time I stop the local TX the scan picks up GB3NQ on 1316MHz
