[Elecraft] KAT2 several questions

[Rolf Moberg]

I've been using my K2 with KSB2 several months now. KAT2 was ordered and 
built in this week.

Some problems:
Page 16 in KAT2 manual, Bridge Null Adjustment (C55)

I didn't get any better reading in adjustment. CALn was 010. Tuning was 
very sharp and it was not easy to find the best value.

Power calibration in page 17 was the next problem. I dont't have good 
external power meter so I tried calibration with RF probe. There weren't 
any written instructios where to connect RF probe's crocodile clip and 
where to touch by probe tip. I guessed and tried power calibration by 
measuring DC voltage with probe from KAT2 J1 antenna jack soldering 
terminals. However, when setting requested power to 5W and doing CALP I 
noticed power level in LCD display was climbing smoothly from 6W to 
upwards. DMM told the voltage in the beginning was about 12.8V and it 
was goind up smoothly. Adjusting R1 (forward potentiometer) didn't help 
to get any more clever or better voltages.

I decided to borrow a good wattmeter from somewhere. And re-installed 
the top cover. Power calibration will be done later. I wanted to test 
KAT2 antenna switch and antenna tuning.

Antenna switch is working. The big question are the relays. I can hear 
them clicking when scrolling through ATU menu as described in manual. 
However, no relay clicks are heard when pressing TUNE in CALP mode. Why?

Please help!
