Ken,
I have not used my KXPA100 and KXAT100 with my K2, but it can be done if
you add a keying output circuit to your K2.
The KXPA100 (and KXAT100) take a dit or two to 'sync up' with the K2,
but other than that it works quite nicely.
OTOH, the KPA100 and KAT100 follow the K2 band changes automatically.
But if you are mounting the KPA100 and KAT100-2 in an external EC2
enclosure, you will need the KIO2 (or a special cable to pipe the
required internal signals to the EC2 enclosure if you do not wish to
have a computer control connection). You do not need the amp keying
circuit with the KPA100.
So those are the requirements for either setup, take your pick. The
price of the KPA100, KAT100-2 and EC2 enclosure is about 3/4 the cost of
the KXPA100 and KXAT100 kits - no soldering with the latter.

All,
Have updated the firmware and put in the keying mods on my K2. Also had
a friend with some great test equipment verify that the new keyinh
waveform is as it should be to prevent key clicks when using an amp.
Now the dilemma. Torn between the K2/100 amp, and maybe a KAT100 in a
separate EC2 case or a KXPA100.
I'd like to hear comments from those that have used the KXP100 with or
without the tuner to amplify a K2.
Are there any special considerations that need to be taken into account
when using the KXPA100?
How easy is it to add the tuner later to the KXPA100?
Thanks in advance for any/all comments.
