My K2 has recently begun making a slight bit of a "chirp"-noise in my headphones on the T/R transition when I do CW. Not a chirp in the classic CW sense of the word, when the other guy hears it, but a little bit of a tone in my own headphones.
My K2 is a 10-watt "rev A" unit, firmware revision 2.04P 1.09 with KSB2, K160RX, KAT2, and KNB2 options. The only thing I've done to the rig recently is to replace the AF and RF gain pots and I didn't notice this "chirp" phenomenon until sometime after I replaced the pots. This K2 does not have the alternate AF mod installed. I've noticed this phenomemon in 80m CW, and I key with a manual key. I've heard it with crystal filter settings of 700 and 400Hz. It doesn't seem to matter if I have AGC set to fast or slow. I do tend to have the RIT engaged--my QSO-buddy's old OMNI D has a bit of drift. Any suggestions? Did I break something when I replaced the pots?
