Hello Hans,
That device is working very, thank you for it. Anyhow, I noticed two things.
1) it does not start transmitting just after I plug it - I have to
retune it!
Output says it is tuned to 95.160000 MHz by default, but it is not.
After I issue retune, just to same channel it starts working.
$ v4l2-ctl -d /dev/radio0 --set-freq=95.16
2) What is that log printing?
