Hi Bob, hi Mike,
Thank you very much for providing the information and video! I had already read page 63 in the manual and adjusted volume at every possible place in my smartphone. Also, the settings in FT8CN were tested by me. No way to get RF out (except for the very first time after a restart of FT8CN). The QMX always showed two points indicating too low volume coming from the smartphone.?
However, when I tried my Android tablet, it worked first time I tried. The tablet has exactly the same settings in FT8CN and I use the same QMX with settings unchanged and the same USB-C-cable.
So, my lesson learned is that the smartphone seems to output a too low audio level even with 100% and my tablet works with exactly the same settings. Strange ...
