[Elecraft] K3 Beta firmware rev. 2.57

[Joe Subich, W4TV]

It measures very close here as well.  

Even though the power calibrations had been done previously (this 
was the factory built s/n 622), I did need to do the wattmeter and 
power level calibrations again at both 5 and 50 watts before the 
AM carrier power was within the 22-25 watt range across the spectrum.
Without the recalibration I saw 30 watts on 160, 25 on 20 and 45 on 
10 meters. 

73,
