Hi,
There is no such issue in SunSDR2 PRO, mentioned Mic1 issue concerned only some SunSDR2 DX TRXs from the 1st batch.

Hello Roman, a few days ago I acquired a SunSDR2 DX ... could you answer if this serial number EED06202100456 has the correction for the mic1 ... as well as knowing which batch it belongs to.



Greetings and thanks for attention.
