[Elecraft] K2 Looking for a KPA 100 amplifier

Mike,

To amplify what Dave has said, let me make 2 points.
1) The KPA100 fits on top of the K2 in place of the QRP top cover. 
Anything mounted in the QRP top cover is physically replaced by the 
KPA100. In your case it will be the KAT2 and KIO2.  The KPA100 fits 
physically on the top of the K2 in the same place as the QRP top cover. 
They cannot both occupy the same physical space.

2) If you need a tuner for your antennas, then it will need to be rated 
for the full power output of the 100 watt (KPA100 equipped) transceiver. 
  The KAT100 will do that job nicely, and integrates well with the K2.

If you ever plan to operate portable, then you can remove the KPA100 (6 
screws) and put the QRP top cover on in its place.  That will give you a 
more lightweight portable package.  If you are hiking, the less weight, 
the better.

73,
Don W3FPR

There is reference to testing the KPA100 at levels as low as 5 watts. So that tells me that the rig can still be used at QRP levels with the KPA100 installed.
