[Elecraft] Is my K2 XMIT Current High?

1.7 at 5W and 2.2A at 10W is OK. Depending on the band, power supply voltage 
and SWR of the antenna the transmit current can go up to 2.6-3A. Into a dummy 
load at 13.8V 2.2A is well within spec. We should probably open up the range 
in the manual :^).

Lower voltage power supplies, and lower impedance loads, will require more 
current to get to the same power level.
