[Elecraft] K2 output @2W

[Leigh L Klotz, Jr.]

The HFPacker amp has a 3dB pad on the input so you might need to take 
that into account.  I use mine with a KAT100 on the output and an 
internal KAT2.  I disconnected the Vrfdet on the KAT100 cable as it has 
the amp in the gain loop, and the K2 software only knows about the 
KPA100.  With the KAT100 enabled, the KAT2 is put into passthrough 
mode.

The K2 power control seems about the same for me with the amp in or out 
-- 1.7 gets 1.5, and 2.0 gets 2.5, and there is no choice between, as 
measured by the KAT2 internal Vrfdet.
