[Elecraft] sidetone problem

[Don Wilhelm]

Cris,

In that case, you have firmware 2.04R which locks the sidetone source at 
U8-4.
Is your K2 Serial number below 3000?  If so you must do the sidetone 
source wiring changes as shown in the KIO2 or KPA100 manual.

If SN3000 or above, you have a problem that needs to be found.  Do you 
have an oscilloscope to aid in troubleshooting?

73,
Don W3FPR
