Re: Good working QCX goes bad... No transmitter output, strange IC3 voltages...
Still not right... with all new semiconductors, still have a strange reading at pin 3... about 7.5VDC with a small AC component of about 100mV (probably from PS ripple etc). I've pulled all the power

Congratulations, Hans! A clarification on firmware, please: Rev 1.03 will be compatible with the earlier board rev, with the pull-up resistors? And not that anybody would do so, but just to be clear,

Re: Ultimate 3 125 MHz Calibration
Randy No, I think you should see something. I upgraded my U3 to U3S long ago so do not remember much. All I can suggest is to check voltages are OK and no bad joints, pins not inserted correctly on

Re: #QCX+ #QCXmini #WSPR beacon callsign length #qcxmini #wspr
Hello Cristi Yes, you can add /P in the WSJT-X programs but the way it handles it is sending two WSPR messages instead of one, with the disadvantages I mentioned. The actual WSPR protocol can only
