[Elecraft] K2, distorted audio signal

[Wolfgang]

Thank you very much for the information. I hope the reply email works in 
the thread.


I have added two pictures of the RF board's U4 area here. Nothing out of 
the ordinary can be seen here.

I need to think about it first, as the connections are not yet clear to me.

Here is some additional information:

- I have had the K2 for several years and have not experienced this 
problem until now.

- Since spring, however, I have been using the K2 more frequently. It 
only operates in CW mode and is mostly used on the 80m, 60m, and 40m 
bands. The 40m band and CW are normally set after switching on.

- The first time the problem occurred was two weeks ago during a hot 
spell (up to 95°F). This means that the K2 was exposed to warmer 
temperatures for a longer period of time during the day. It is unclear 
whether there is a connection.

- Since then, the problem has not occurred regularly when turning on the 
K2, so I have to wait and see.

- I discovered by chance that the K2 works normally again when I switch 
to the 20-meter band and back.Currently, the connection is still unclear 
to me.


Iwillthereforewaituntiltheerroroccursagainandthentrytogathermoredetailedinformation. 
Then I will report back here again.
