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,
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.

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
..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.

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

Look at the top of the K2 - does it have a black finned heatsink? If
so, that is the KPA100.
If you have 2 BNC connectors at the ANT1 and ANT2 positions on the upper

Changing from the KPA100 to the QRP top cover is a matter of removing 6
screws and removing the 4 cables between the KPA100 and the base K2.
Add the QRP top cover and you are done.

consider mounting the KPA100

The easiest way to do this, if you will be changing from one
configuration to the other frequently, is to mount the KPA100 in a
separate EC2 cabinet. I do this with my K2, and it works great. I also

If you do not already have a KPA100, you might look at the very very soon to be

Hi All,
I've just spent the day fine tuning my KPA100 - measuring the output power
on each band and trying to improve it. Initially I was getting a HI Current
warning on each of the bands from 160 through to 40 (all into a dummy load),
but not on the rest. In all cases the maximum power I could
Mike,
How are you measuring power out? and how good is your dummy load? (check it
with your antenna analyzer) - that will get the first things out of the way
for us.
The Hi-Cur indication is coming from the base K2 and not the KPA100 - it
indicates that the base K2 has to drive the KPA100 too
