[Elecraft] K2 Looking for a KPA 100 amplifier

[Dave Van Wallaghen]

Mike,

No, the KPA100 actually physically replaces the top cover where the KAT2 
is mounted. The KAT2 is not designed to work with anything but the basic 
10 watt K2 version. Yes, the K2 with KPA100 can produce anywhere from 0 
- 100+ watts. The KPA100 amplifier stage is actually bypassed for the 
0-11 watt power range, but no way to use the KAT2 in that configuration. 
Only the KAT100 ATU or similar brand that can handle 100+ watts can be 
used as an ATU after the KPA100.

73,
Dave, W8FGU

>I’ve looked at the KPA100 manual and I saw that it has it’s own I/O input and circuitry. But I didn’t see anything saying that the installed KAT2 would not be used. 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.
