K2 - Rsspy sound on CW

[Jerry Deibel]

Happy New Year everyone,
I have been using my K2,  #4472,  for  quite a while on the digital
bands and all ok.  I have been building up my code before I tried it
with CW and just  today I made my first CW contact with it.

I got a report of it sounding very raspy, so I monitored it with another
rig and sure enough the CW sound horrible and raspy is a good word for it..

Does anyone have any suggestions, maybe just a menu option, etc.  before
I start digging into it.

Jerry, N2UZ

Move it away from the power supply. The K2 is sensitive to magnetic fields.

Jerry,

I had exactly the same problem. The culprit is probably the small choke
RFC15 under U4. When you bend the leads to take up that odd form between the
pins, it's very easy to break the internal connection, and the effect is
just as you describe. If you haven't got the correct value handy, try any
small fixed choke just for testing.

Hi Jerry,

Sometimes RFC15 broken, causing problems at some frequencies for the PLL.
