Brief test today, 18Ks DVB-S using Pluto.
Custom ffmpeg script to generate this low data rate - not quite working correctly yet.
kiwisdr allows IQ audio of 20KHz span output from the soundcard, this is then fed into sdrangel which does the decoding.
Work to be done but a decode is possible!!!

Wow...is this via your local SDR (nevertheless VERY impressive).
The future is even less BW....and a user guide for SDRAngel
Great work

Re: 29MHz trans Atlantic DX...
Got my 10m Slim Jim back up and running and 2 watts from Mikes transverter. Can't generate anything less than 66ks even with DATVEasy ATM, keeps saying video bit rate needs increasing if I try less than 66. Thought it autoconfigured? Fast forward on my MRF single device amp next, but watching on 29.00 / just in case.....
The repeater on 29.62 is fully quieting with me at 14:15 and I just worked SV2HJW on FM simplex. The magic band....

Going forward i will be using 29.150 centre as it was pointed out that the Satellite section starts at 29.300.
29.250 was a bit close for any wider tests.
Conditions not as good today after yesterday's aurora.
