Hi to all - and Simon!

My setup:
WIN10, SDR-C latest copy, limeSDR mini

Has anyone of you experienced this:
You transmit audio (e.g. microphone or FT8 from a virtual cable) and everything runs fine. For some reason which I did not discover yet SDR-C indicates "TX" and incoming audio (see ALC in the attached screenshot at 25% from FT8) but there is no HF-out like you can see in the waterfall.

Is there an explanation for that? This happens sometimes rather soon after starting operation, sometimes after a long time (e.g. one hour) while having QSOs.

 An additional information is: if you would like to close SDR-C in this state it "hangs" and you have to force the closing by clicking 2x at the "close-cross" in the upper right corner of SDR-C´s window. After the second click you see the window embedded below this text. Here finally you can close the program.

73 and tnx for thinking,
