[Elecraft] K3s Output on 6M

[Bob McGraw K4TAX]

 From page 9 of the manual: "K3S/100 typ.  Suggested max from 51 - 51 
MHz, 85 W,  52 - 54 MHz 70 W. "    There are other specs related to 
K3S/10 and transverter outputs.

Looks like 100 watts is a good number from 50 - 51 MHz.   I see that on 
my radio and I've not checked power above 51 MHz.   The internal tuner 
operates at around 5 to 7 watts output while resolving a match.  Using 
the internal tuner seems to tell me the external devices are not 
operating with a 50 ohm nonreactive load attached.  In that case, being 
voltage sensing devices, the load will affect the power indications.

The point which would concern me most is having 3 different power 
measuring devices which give significantly different values.
