[Elecraft] K3 Wattmeter Calib

Hi

When I first did this calibration I could not get above about 4.7 watts at 
the 5 watt calibration. The number indicated on the LCD would not go below 
30 and ended up set to 30 even though the power out was still low. The same 
with the 50 watt calibration. After downloading the latest firmware (1.78) 
This works better. I could bring the power up to 5 watts before I ran out of 
range on the adjustment. The 5 watt number is 77 and the 50 watt number is 
65 indicated on the LCD.

I am not sure if the transmit gain interacts with this adjustment but to be 
safe I would do the transmit gain first then the wattmeter. This could also 
be the reason my wattmeter calibration worked because I had done the 
transmit gain and then went back a redid the wattmeter. So I am not sure the 
firmware upgrade or the calibration order fixed the problem.

Thanks
