[Elecraft] K1-4 4 band version gone?

The K1 remembers the frequency display calibration settings (OFS)
for all *nine* HF bands between 160m and 10m (60m is excluded),
and automatically uses the one previously stored for a particular
band when that band gets assigned to a filter board's b1 or b2.

It is worth noting that a small problem will arise if multiple
KFL1-2 boards are built that duplicate one of the bands...such
as a board for 40/20 and a board for 40/15, both for the same K1.
The K1 MCU can remember only *one* frequency display calibration
setting per band.  In the example I use above, one of those two
boards will have some calibration error on 40m unless the 40m
heterodyne crystal frequencies of both filter boards are very
nearly the same frequency.  They'll likely be close enough.
