Hi Patrick and Paolo,
I do have the RSD2duo working with SDRuno v 1.4 beta version 1 with API 3.07 and RSP_TCP v1.1.
I can get the radio to tune BUT only on the default antenna port. The P0, P1, P2 commands that I
had been able to use from batch files no longer seem to work. The Bias-T command does work
from MultiPSK, but only on the second tuner, which I can not seem to activate with the -P1 command.
I have a question though. Are you trying to use this process while SDRuno software is running? If so, that
will not work and will give the same error.
I have not had to use the 1234 info anywhere.
This effort has become very complicated. I hope this helps,
