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,
