KN1CBR, a long-time Elecraft user and builder of several K2
transceivers, is downsizing and has a K2 + KAT100 system that he wants
to donate to an organization that helps new hams get started. Donee must
be a school or 501(c)(3) organization that will use the gear rather than

Digi-Key has high quality connectors. I would guess Mouser does also.

I’m looking to build the cable shown on page 25 of the KAT100 manual to
allow me to use a PC for logging while also using the KAT100 with the K2
aboard the USS Slater.
Anyone recall any pitfalls or DB9 connectors to avoid? Amazon has some
cheap ones but reviews are that they are, well, cheap.
I’m looking to buy the KAT100-1 antenna tuner for the K2. I believe the -1
model is the slim model that the K2 can sit on top of. I don’t want the -2
model which I think is the enclosure that is the same size as the K2.
Elecraft has the tuner on back order for 2 weeks AFTER Covid-19 restrictions
Hi to all,
My K2 includes the KSB2 SSB, KDSP2, and the K102. The external KAT100-1
ATU has also been completed.
I've just received kits for the KNB2 and the KPA100 and I'm planning to
complete them in that order.
After a lot of research in the archives of this list, I've now belatedly
Kev,
You will need the EC2 as well as the KAT100PNL kits. The KAT100PNL kit
has only the front and rear panels as well as the headers required for
the KAT100 board.
You may also want the tilt stand if you want to tilt it the same as the K2.

Hi
I have a KAT100-2 ( KAT100 in the full height EC2) and I would like to

Perfect companion for your K2. KAT100-1 Auto Antenna Tuner. 150W. Built from
kit in December, 2011. Never used. All tests successfully completed. (Buyer
will need to complete rig-half of the K2 interface cable to suit your
installation).
Complete with all interconnect cable parts,
The KAT100 auto tuner has been sold. Thanks to all who replied.

Although the EC2 was purchased new (Feb 2009), it has a few very slight scuffs
I'm considering adding the KPA100 and KAT100 to K2 #337, and building

The KPA-100 and KAT-100 must be powered up before the K2, or at least at

Yes, the KAT2 HiPwr indicator only comes on when the KPA100 switches in

Hello All,
I hope that someone can suggest where to start tracing down a

There is nothing unique to 40 meters in the KAT100, *but*.
Behavior like that *could* be related to a parasitic oscillation in the
KPA100. The parasitic usually revealed itself during a TUNE operation
with the KAT100 also installed.

Since you do have early updated version of the KPA100 - there is one
thing yet to check, and that is the value of C31. If it is not a .22 uf

one if you ask - the part number is E530295.
