[Elecraft] RE: K2 Dial Calibration Information

[Don Wilhelm]

Andy,
The information I have understood is that the firmware does not write the
BFO values until the BFO frequencies are actually changed - on that basis,
changing the filter bandwidth would only write the new filter bandwidth to
the table, but not the BFOs.

I may have understood incorrectly all this time, but until Wayne tells me
differently, I will continue with that assumption.

If you were successful - have you considered that it may have worked 'just
because'?

I meant to post the list when I discovered it, but I believe
that instead of bumping the BFO freq, you may be able to bump
the filter bandwidth up a notch and back and have it store the
new (post-CAL_PLL) setting for the BFO as well. Or am I wrong?

All I know is I had the BFO freqs tweaked just right, such that
all eight CW bandwidths (4xNOR/4xREV) stayed on zero beat. I
then installed the K160RX and had to redo CAL_PLL -- and instead
of trying to remember that the BFO freq was 4913.88 or whatever,
I switched to the filter bandwidth display of CAL_FIL, and
bumped that up and down again, and my zerobeat was restored.

I was meaning to try that again and post to the List once
I was sure, but maybe this does work after all. It's certainly
easier to remember that your filter bandwidth was 1.00 kHz
and then bump back there, than it is to remember what your
BFO freq was (as it's bobbling between two digits, usually).
