K2 with KPA-100

I should have first stated that I do not have any K2 or any amplifiers
or tuners. Just asking questions in anticipation of getting a K2.
Reading manuals and seeing photos of k2s is not as good as seeing the
actual unit.

I am aware that the top of the KPA-100 is a black fined heat sink. I
was not aware that the KAT2 could not fit below it.

Now I know why Elecraft came out with the K3. Confusion reigns at least
for me. Think I will just get a KX3 which is very much like my K3 which
I have had for over 10 years.

Thanks to every one who responded.

73, Gene W2BXR

Re: K2 with KPA-100

Well, proceed as you must Gene, but building and operating a K2 is an
experience in radio like no other. And "Mr. K2" [Don] is always here to
help.

Gene ...

if you were planning to buy a K2 kit, you should do that.   It was a
pleasure, and a lot of fun to put together.   The KAT2 will not work
with the KPA100 option for the reason Don pointed out also, and Don
correct me if I'm wrong, I'm not sure its rated for more than 20w.

The KAT100 is a great option, and is designed to sit below the K2/100.
If you need pictures, you can check out my K2 build pics here:

Re: K2 with KPA-100

..unless you build it in the ‘Twins’ configuration. Then you have the KAT2 and KAT100 both available in the system along with the KPA100. But you need another EC2 enclosure.

Re: K2 with KPA-100

Brian,

Even though the KAT2 and the KPA100 are present in the "Twins"
configuration, when the K2 MCU detects the presence of the KPA100, the
KAT2 is bypassed and set to connect only to ANT1.
In other words, the KAT2 will not work with the KPA100 present.

If an ATU is required with the KPA100 in-line, the KAT100 or other ATU
between the KPA100 output and the antenna is necessary.

Yes, the KAT2 is rated at up to 20 watts. The KAT100 is rated at up to
about 150 watts.

Unfortunately the KAT100-2 doesn't seem to be available any longer, even
though it is still described on the man page for the tuner.

Re: K2 with KPA-100

David,

That is true. The problem is that the EC2 enclosure is no longer
available. The supplier is no longer in business.

Fortunately, there is a "cure" (even if it is only temporary - until
Elecraft runs out of the panels).
Elecraft still has some KAT100-2 front and rear panels available, and
one can make up the rest of the enclosure with metal panel parts from
the K2. As far as other non-metal parts to be added to the KAT100-1,
there are only 3 headers.

If anyone wants to go that route, I can provide a list of parts to purchase.

I have complete, original, unassembled, KAT100-2 in the original box
that I never got around to building. If anyone is interested - contact
off list.
