[Elecraft] K2 The KAT2 Automatic Tuner

[Ray Spreadbury]

Hi

 

Have just built & now testing my KAT2 atu and got as far as Bridge Null
Adjustment on pages 16/17 of the instructions. . I appeared to adjust C55
for a 000 reading OK.. When I took the voltage reading from pin 1 however
the reading my DMM gave was 0.6mV in receive mode rather than 0. In TUNE
mode at 5watts it is 4.65 volts rather than the expected 3 to 4 volts.

 

Are these small voltage differences significant or can I proceed with
installing R6?
