[Elecraft] Sidetone

[Don Wilhelm]

Paul,

First check to be certain you have 8R HOLD set on - accessible from the T-R
menu, edit the parameter (move the cursor to the right) and tap the DISPLAY
button to toggle 8R HOLD or 8R NOR.

Then check carefully to determine when the click occurs 1) at the beginning
of the transmit cycle or 2) at the end of the cycle (hint, set the speed
slow and send a few dashes).

Lastly, turn the AF GAIN to zero (not the RF gain as someone else posted)
and see if the clicks remain.  If you have clicks with the AF Gain at zero,
they are coming from the sidetone generating circuit, but if they are only
prsent with the AF Gain advanced, they are coming from the muting circuit.

Before making any suggestions here, try the above items and then tell us if
you have both the KDSP2 and the KPA100 - if you have both, has your KPA100
been upgraded with the latest changes (KPA100UPKT) - if not, that is your
first step.

73,
Don W3FPR
