That is the easiest way to do it and it does work! Any change in anything
seems to cause a write to take place.

| Don, and everyone -- you say:
|
| = = =
|
| Run CAL FIL.
| Internal probe (FCTR) on TP2.
| Set all BFOs - (writes the BFO/DAC values into a lookup table).
| You must change each BFO setting to have new values written into the
lookup table - even if the current setting is the correct! Move the BFO up
one 'notch' and then back to the previous value. The new values will be
written to the lookup table and will then be used in computing the frequency
value for dial display.

| = = =
|
| 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).
