[Elecraft] Conditions, shmonditions: DXing anyway

I generally use 440 Hz for sidetone/pitch, thinking that it is a 
familiar standard musical note and perhaps is more recognizable to the 
brain in some way. I don't know if that has any validity or not...

One thing I would dearly like to have is the ability to listen to the 
actual signal as I am changing PITCH. Unfortunately, as it is now, when 
PITCH is turned on the received signals are covered by the steady tone. 
That makes it not very easy to find the optimum pitch for a signal under 
current conditions.

73,
