[Elecraft] Faint clicking sound in headphones

[Bob McGraw K4TAX]

I hear something which is very slight in QSK mode but not in SEMI mode.  
My observation is that it is "very" slight.  Headphones with higher 
sensitivity may be more prone to exacerbate the the click. I speculate 
it is the leading edge AGC recovery in between CW elements.  Being on a 
dummy load, there would be no AGC transition to noise as would appear 
with noise from the antenna.

If you think it is RF related, turn the PWR down to 1 watt or operate in 
TEST mode.  I suspect however it is switching related and not RF related.
