I assembled my uBITX as a WSPR transmitter.? I use a SignaLink USB for receive and transmit audio plus PTT.? Everything works as it should on 30 meters and lower.? On 20 meters and higher when, when PTT is activated, the LCD shows "Band Select" as if the push button has been pushed.? This is with no audio meaning no RF output.? I tried adding a bypass cap to the pushbutton which didn't change anything.? The only way to get it out of TX mode is to turn off the power.
