My K2 started crackling and slowly lost its audio today. Sensitivity seems ok.
Kinda sounds like one of my old tube rigs before I recap….
Thanks

Thank you very much for the replies.
The chirp I'm hearing on T/R transition isn't a shift in my sidetone; it
sounds more like a geniune signal somewhere else on the band and my K2 is
taking just a tiny moment to stabilize the receive frequency as the K2
switches from transmit to receive. It's a
All bands? There was an advisory a few years ago about VCO voltage
limits and frequency settling time when changing state TXRX or the reverse.
Just a thought.

I've only noticed it on 80m.
Thanks for letting me know about the advisory--I'll look for it.

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
Eric,
I really cannot associate any change in sidetone pitch (chirp) with
the change of RF and AF gain pots, but I would strongly recommend that
you add the sidetone pitch (10k series resistor and 82 mHy shielded
inductor) changes to your Rev A K2 to give a better sidetone pitch. In
fact, I
I have K2 #1239. I did all the A to B mods, and the rest of them, and
added the DSP. Made a huge difference by my reckoning. I did them all at
once. Gl 73, Guy.

I have a K2/100 an Icom 756Pro. I am trying to use a switch box to switch a
Icom SP-21 8 ohm speaker between rigs. When I have the K2/100 connected to the
SP-21 I have to turn the audio control way up to hear anything, but when I
switch back to the Icom radio its audio output is OK. Is this
Bob,
Your biggest problem is the 8 ohm impedance Icom speaker. Most solid state
power amplifiers will deliver more power into a lower impedance load - the
K2 audio power output spec is for 1 watt max into a 4 ohm load - when the
audio output amplifier tries to work into an 8 ohm load, the power

As stated many times by Wayne B., the K2 design criteria was for low
receive current consumption and that is one reason that the K2 has
limited audio power output. The current consumed by a higher powered
audio stage could likely take more current than the rest of the
receiver.
