I sent the note below to support, but thought I would also post here.
It has been working fine for years. Opened the case to do an alignment
and developed a problem. Anyone on the reflector have a suggestion?
--------------------------------
I have an elderly K2 (S/N 02600) that had been working well. After all
these years, it was about 200 Hz off frequency so I proceeded to do an
alignment. Got it pretty close, but the trim cap (C22) would not pull
quite on freq. Close enough maybe...
Proceeded with band by band alignment / peaking. All bands peaked as
expected except 17M, (maybe 15M too).... No change when adjusting C32
& C34 for 17M.
More symptoms:
* Stepping up the bands is normal until going from 20M to 17M. Then:
17M and 15M are reversed from normal progression.
e.g: 160, 80, 40, 30, 20, _*15, 17*_, 12, 10
* System Rx noise is significantly reduced on 17 & 15.
* In CW mode, the Tx freq is OK on all but 15 & 17.
The display reads as expected on 15 & 17 - as VFO is adjusted. But, my
freq counter indicates the actual Tx output freq is different and does
not change when the display freq is changed:
Example... For 17, the Display indicates 18.120, the output is on
18.766+-. For 15, the display indicates 21.265, the output is
21.434+-. It is also receiving on the (actual but wrong) Tx freqs.
Changing the VFO changes the display but does not change the actual TX
or Rx frequency which seems to always be the same.
I am stumped!!! Can you offer any suggestions as to what might be
happening???
Thanks,
