[Elecraft] FR - KX2 max output now 12 watts (experimental)

[John Oppenheimer]

Used the new FW during my early morning 40M CW session. Used KX2 #80
with external LiFePO4 battery and inline W1 Power Meter. Antenna SWR =
1.3. The W1 12W LED does turn on. Measured DL1 power is 11.8 watts.
Ambient operating temperature was 22 C.

Sent many CQs before receiving an answer. Had two long QSOs. Maximum PA
temperature during CQs and conversations was 41 C.
