[Elecraft] K3 Power calibration and current consumption

[Ken Kopp]

I may well be the only one "caught" by this, but be sure that
the TRANSMITTER GAIN procedure on pages 49 and 50 
of  the manual has been done, but also include the 100W level.  

IMO, the first paragraph under WATTMETER on page 49 
should read "... 5 W, 50 W , 100 W (K3/100 only) .... etc.

If you only use the Utility's calibration procedure as suggested
in the second paragraph under TRANSMITTER GAIN on page 
49,  the 100W level will --not-- be calibrated.  

If there's a reference in the manual to setting the 100W output 
level, I've overlooked it.  I spent a number of hours trying to get 
my external Bird(s) and the "dialed-up" power level to agree.  In 
my case the PA was delivering 110 - 115 watts to the dummy 
load at the "dialed up" 100W setting.  

This condition might account for higher than expected current
consumption. 

Once I set the gain level at 100W and then ran the Utility's 
calibration routine, the Bird(s) and the "dialed up" power agree 
throughout the 0-100W range. (:-)
