Dave,
A comment on your item #2 - while the VFO in the K1 can be modified to
have the bands begin 25 kHz up from the lower band edge, if you do that
for one band, then all bands will start up 25 kHz. That is a problem
with 30 meters where the normal tuning range begins at 10,100 kHz, and
most of the CW operation is between 10,100 and 10,125 kHz. If you move
all bands up by 25 kHz, you will not have a usable CW tuning range on 30
meters.
Alternately, one could leave the VFO frequency as specified in the
manual and order custom crystals to place the start of the band 25 kHz
up from normal, but that is an expensive undertaking.
Note that the 4 band filter board must include 30 meters as one of its
bands. There are only 2 low pass filters on the 4 band board and only
40 and 30 meters plus two bands of the 20m, 17m, 15m set are the only
possible choices. The 2 band board can be configured for any 2 bands -
80 thru 15m although there are a few 2 band boards that have been
modified to work on 160m and 10 meters.

Hello, all,
I'm about to order a K1, and thought I'd ask your opinions about
various options and configuration choices.
1. I understand the tuning range can be set to either 75kHz or 150kHz.
My inclination is to go with the 75kHz range, for the slower tuning rate.
2. Somewhat related to 1), will I be better off with a range of
7000-7075kHz or 7025-7100kHz, or possibly some other coverage.
3. What are your thoughts on the following options? In particular, are
they effective, and are any of them much easier to install during
initial assembly (as opposed to being retrofit)?
A. KAT1 Antenna Tuner
B. KNB1 Noise Blanker
C. KBT1 Battery Holder
Thanks and 73,
Dave KQ3T
