[Elecraft] special request to K2 owners

[Wayne Burdick]

A few postings recently have mentioned an increase or decrease in
operating frequency that occurs very infrequently during CW keying of
the K2. In some cases this may be due to inadequate friction between the
VFO knob and the felt washer, but in other cases it could be a side
effect of the way we cycle power on/off to the optical shaft encoder.

We'll need help from K2 owners to determine if this encoder power
cycling really is the culprit. So I'd like to ask a favor of everyone
who may have seen the frequency shift occur: please make the simple
modification I posted yesterday. 

We're especially anxious to have those who get on the air frequently
make the mod, since the problem crops up so rarely. The more
trouble-free on-air time we observe with the mod in place, the more
confident we'll be that we've found the problem.

It should take only 5 or 10 minutes to make the mod. You don't even have
to remove the front panel controls; just unplug the module. One short
jumper wire is soldered on the back of the front panel PC board.

If you make the mod but still see some sort of frequency shift symptom,
please send me (not the list) the following information:

- the exact operating frequency (down to 10 Hz if possible)
- the VFO tuning RATE selection (and whether the VFO was locked)
- the nature of the observed shift (up/down, amount, regular or sporadic)
- whether or not you had SPLIT or RIT turned on
- whether you were using internal or external keying
- CW menu settings (STL, STP, T-R, IAB, INP)
- whether moving the VFO slightly restores normal operation

Our goal, as ever, is to continually improve the K2's reliability.
Thanks in advance for your help.
