Understand the sentiment, but more attenuation is operationally
contra-indicated if the signals you're trying to work are weak due to
temporary emergency antennas and QRP.

Part of emergency preparedness is understanding various rigs
non-prejudicially for their various strengths and weaknesses and choosing
rigs for strengths and avoiding rigs for weakness as those apply to the
specifics of an application.

These days weak signals and close multiple transceivers call for the likes
of K3's.

At N4C field day we frequently had a CW station and SSB station on the same
band with no interference, and actually without being aware of each other.
No noise, no anything. I know what a K3's hardware AGC kick-in sounds like
and that was also absent. This has been our experience for five or six
field days now, and together with the small light size and portability,
makes the K3 a top pick for FD. Not because of Koolaid, but because of
proven suitability to the application.

I'm waiting to hear about KX3's for FD, especially battery operation, long
a specific niche for K2's.

We did not have a K3S or K3 with KSYN3A for evaluation. We have a standing
question of whether K3S/upgraded K3, with some horizontal separation, will
be able to operate a few KHz away from each other on the same band/mode
segment, e.g. the 40 CW station, and the GOTA station on 40 CW at the same
time. Perhaps next year we will find out.

N4C operated at the Grey Goose Farm near Creedmore, NC. The group was a
large portion of the North Carolina East chapter of the Potomac Valley
Radio Club. This group contains a significant supply of K3 owners, who
regularly bring K3's to FD and multi-op contest events. For them
portability and immunity to high RF environments are top-of-the-list
reasons for purchasing K3's as opposed to other choices, easily serving FD
style applications.

At NY4A, also primarily manned by PVRC NC East members, going back pre-K3
the FT1000MP was the main rig, which had gradually replaced all the
stalwart Japanese rigs of prior years. For some time the MP was the only
rig seen there. When the K3's and other rigs with new generation RX came
out, and the differences became known, The MP's were gradually replaced. A
tally of the list of MP owning operators who had manned NY4A at some point
indicated that 11 MP's had been replaced by 14 K3's and one Orion. Of that
group, no one owns a Flex to this date. But neither would I consider any of
them to be a "Flex-basher".

I do know Flex owners, single home stations, who get outstanding
performance away from high-RF multi-TX operations. Various problems with CW
and spectral purity seem to be a continuing manufacturer's emphasis for
solution. They're out there on a particular bleeding edge, with a
particular emphasis, with its own set of problems. We'll just see what they
do. Bashing not necessary.

UPS currently has my 2015 K3 upgrade round: KXV3B, KSYN3A's, a second KBPF3
(A version) and finally a P3 and P3SVGA. I will get the new audio board
when it's available.

Regards All,
