[Elecraft] K2 damage

Wed Jun 18 06:52:01 2003

Kevin,

Sorry, I did not find the time to read the listserver for some days.

I found a very smilar problem when i repaired a customer K2. No sidetone
and some strange display readings. In the menue the Sidetone pitch
showed 2.35 instead of 400 too 800. Tuning this value to another value
ended with a total hang of the processor as soon as i came do specific
number somewhere in the area of 1.7... 

Totoal reset didnt help. I solved the problem by changing the eeprom,
now this K2 is ok again.
