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,

Wups! Okay, that exhausts my tiny knowledge of the switching
issue! Perhaps
Don or one of the other guys here will have some more ideas.
Never hesitate
to ask - believe it or not, that's what this reflector is for (although at
times we wander so far afield one might not realize it, Hi!)

Sounds like you have t-r in the MENU set to 0.00, Paul. That makes the
t/r delay zero so you hear the actual switching going on.
Try 0.01 or greater for smooth t/r switching.

I am hesitant to put this question up here because I have seen so many
posts about it but here goes anyway. I love my K2 sn 05834 except for
one thing...the sidetone. There seems to be excessive thumps (clicks?)
on both make and break, especially when using the internal speaker. I
know there were alot of comments about the sine wave improvements, but
has anyone been able to eleiminate or reduce significantly the thumps?
Thanks for the response, but changing the T/R timing was the first thing
I did.

8R Hold is set on...t-r delay at .005....no difference with audio
gain....but I'm beginning to wonder if it isn't just the speaker
resonating in the case at certain frequencies...when I change the
sidetone freq to 500hz the pops disappear...and they aren't there in the
headphones at any frequency...I will continue to play with it and see
what else I can discover... Thanks for all the input.
