[Elecraft] K1 VFO frequency range change

[Sandy W5TVW]

This is the MAIN reason I changed the VFO span, to get up to 7100
to 7150 coverage.  At the same time, I pulled the 30 meter crystal and
installed the 10-10.15 crystal originally supplied if the "150 Khz span" was
desired.  I also replaced the original plastic shaft 10 turn tuning pot
with a metal shaft/busing replacement, as my old pot was getting a bit
sloppy mechanically.
Really like this little rig.  Now I wish I could have 160-10 meter coverage
without changing RF boards!  Wayne:  THAT would be a feat in the space
allotted for the RF board!  A 9 band board?

|
| That's why I've always termed this option as the "180 kHz" option rather than Elecraft's "150 kHz"
characterization.

|
| There's a lot more Morse activity above 7120 kHz.  To me, that's more than worth the additional
VFO span.
|
| You mentioned having changed out the 30m hetrodyne crystal, which I assume means that your 30m
band tuning now starts near 10 MHz.  Reducing VFO span to, say, 125 kHz will mean that you'll only
be able to cover about the first 20 kHz of the 30m band.
