[Elecraft] K1 AF sidetone loudness problem ?

[Don Wilhelm]

Roland,

I have never seen that kind of problem.  It does sound like something 
may be corrupt in the EEPROM.
You may want to try resetting the K1 to factory defaults (which wipes 
out your menu settings and replaces them with the stock factory defaults).
Before you do that reset, record all your menu settings so you can 
restore them - but some such as the CAL OPF values will have to be done 
from scratch.

Do know that the sidetone level on the K1 does vary with the setting of 
the AF Gain control, so if you are change the AF Gain during 
transmission, the sidetone level may increase/decrease with the AF 
gain.  Still, a loud sidetone with SL L set to 1 should be very quiet.

If the reset does not correct it, I would first replace Front Panel U2, 
next FP U1, and last FP U3.

73,
Don W3FPR
