[Elecraft] Amp for a K2

[Don Wilhelm]

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.

73,
