[Elecraft] KX3: Weird behavior with WSPR

[Ken Alexander]

Thanks Guys!

That did it!  WSJT-X has a transmit level control and WSPR doesn't. Turn 
out the output level coming from WSPR is much higher than from WSJT-X.  
I had to reduce the Mic Level down to 1 to get it to work.

It's bedtime now.  Tomorrow, I'll reduce the level in Playback Devices 
so I can level the Mic Level the same for both programs.

Lyle, maybe the firmware could be modified so that all of the ALC bars 
flash if the transmitter is being overdriven?  Just a thought. With no 
bars showing the natural inclination is to dial up the level until you 
see something, which turns out to be the opposite of what should be done.

Thanks again gents!

73 - Ken
