My K2/100 occasionally loses audio when it has been on a while with the AF
GAIN turned down (K2 on butnotbeingused). My K2 is an early model in the 2200
series serial number, and the AF mod was done. It also has the KDSP2 and
the 10th digit CW LED zero tuning mod. Whenever I lose the audio, I cannot get
it back by turning the AF GAIN up. The RF GAIN works correctly and will
display all 10 digits if turned CCW while the audio is lost. Signals show up
normally on the S meter as I tune across the band. I noticed that I cannot
activate the DSP when the audio is gone. All other functions are normal. The
only way I can get the audio back is to cut the K2 off and then back on. The
audio returns to normal status and may remain that way until I turn the K2
backoff. I have the K2 grounded, but I notice the display may momentarily
change to either power setting or keyer speed as my hand approaches the K2. Is
this an electrostatic condition I am going to have to live with? Has anyone
else experienced this? If so, what can be done to correct this? Roy Morris
