Hi Alan,
Great to hear that mode2020 is running on a Banana Pi!
I was able to install on Ubuntu 18.04 on a I5-8350. Hardware was just
for EUR 350,- direct from China.
Made some tests in mode 2020 with WebSDRs and on QO-100 satellite.
I am still having problems with correct tuning. Also VAC is not working
on LINUX, so I had to make analog connections - quite noisy.
Do you have any information what to use for VAC unter LINUX? I have been
trying a virtual sink on pulsaudio, but it didn't work correctly as I
didn't see the audio device in FreeDV.
Any other methode to use virtual audio cable on Ubuntu?
regards
Gerhard OE3GBB
