K2 - key pops

[K4JQV]

Greetings;
I have an older K2 #2676 and I have noticed that sometimes (somewhat regularly actually) when using narrower filters on CW (like 400, 200 hz) I get a crackle/pop/psst sound on keying. I am guessing that I need to do the keying waveform mod right?

Thanks!
Jake K4JQV

Jake,

Yes, you should add the keying waveform mod - especially if you have the
KPA100 installed.  BUT, that has to do with the transmitted signal and
keyclicks.

It has nothing to do with the receive part of the K2 during keying.
Go to the menu T-R parameter, and set it to something greater than 006
(6 milliseconds) - then tap the DISPLAY button to change the 8R behavior
to HOLD.

You can try variations on the delay time and the 8R setting to see if
any of those change your receive "pop"  characteristics.
