Thank you Sandy, Tom, Eric, Mike and William and others for your on and off
list answers. I decided to go with 80kHz, and I am waiting my K1 now (last
part for Lisa).
73,

I'm afraid I agree for the most part here. There isn't anything of
interest about 80 khz
from lower band edge. That will probably "shrink" if the "bandwidth"
plans are
implemented anyway as far as CW is concerned.
If you are in a contest and have the selectivity ratcheted down to 200 Hz,
even with the
80 khz. coverage the tuning gets a bit touchy at times. I can't imagine
WHY I'd want to
tune a 150 Khz segment with a "CW only" rig anyway!
My only complaint about my beloved K1 is the RIT tuning is rather touchy
and
can be critical to set. Again especially so with the narrowest
selectivity in.
use! Been thinking of reducing the "range" of the RIT tuning as I VERY
rarely
work with a "DX offset" more than a couple of khz at most.

| Once again, different strokes...
|
| My K1 is primarily a portable radio. At home, I can get WWV on the K2.
In
| the field, I already have a watch. If the watch craps out, I'll ask
someone.
| Gaining WWV is not worth giving up slower tuning on the portion of 30m
where
| I find most CW. My main interest on 30m is county hunting anyway so I'm
| pretty much 10.114-10.116 anyway.
|
| There are more stations from 7000-7050 than I could ever work, but I
| appreciate the slower tuning for that part of the band.
|
| When 15 is open, there are more stations than I can work from 21000 to
| 21060, and very often nothing above it, at least none that I can hear
from
| this location. Again, the slower tuning for a smaller, more populated
part
| of the band is useful to me.
|
| The idea of crossband has never occurred to me as something I would want
to
| do. I can't see the appeal. Likewise, I never use split frequencies so I
use
| the XIT button for SPOT and reduced the range of RIT so it would be
useful
| for me for minor received tone corrections.
|
| We have different operating styles and preferences, thus different
opinions.
| Ruchan has the benefit of matching his operating style and preferences
to
| each of us when he sets up his K1.

|
| I've been using K1 #175 in the USA since November 2000, and I find the
| advantages of the 150 kHz span to be overwhelming, but **only** for use
in
| this ITU region.
|
| IMHO, the 150 kHz span (actually it's about 170 kHz) has a very
controllable
| and acceptable tuning rate (after FP-R19 was added to the design in 2001
to
| linearize the tuning rate at about 17 kHz per turn). I also use a
little
| felt padding placed between the VFO knob and the front panel to give a
| slight amount of rotational resistance. No matter which span is used,
the
| VFO potentiometer shaft needs this extra resistance, IMHO.
|
| >and the added frequencies are of no use to QRP...
|
| No use???
|
| Certainly there is some use in this ITU region, where 7100 to 7150 kHz
is
| excellent QRP territory and the main justification by far for choosing
the
| wide span. Cross-mode (Morse-LSB) contacts in the phone band from 7150
to
| 7170 MHz are possible, since the K1 receiver operates in LSB mode (on
all
| bands). When 15m is hot and one or more of the 6,666,666 different
contests
| is wasting good RF energy, 21100 to 21170 kHz provides a haven for Morse
| QSOs.
|
| >I also built for 10.1 mhz as most of the useful QRP activity seems to
| >be 10.100-10.120.
|
| With the 170 kHz span and the 10000 kHz band edge crystal installed,
time
| and propagation info are often available from WWV at 10 MHz in the USA.
A
| useful capbility.
|
| HOWEVER, if I lived in another ITU region where Morse operation from
7100 to
| 7150 kHz was not allowed, and where WWV could not normally be copied,
I'd
| choose with the 80 kHz span. That is probably the best setup for your
| European K1.
