I am in the course of finishing the KAT2 assembly.
I did the C55 adjustment like discribed on page 16:
Press T U N E button and release it when you see the display change.
Adjust C55 for an indication as close as
possible to 0 0 0 . Tap or hold T U N E again to cancel the C A L n
display and return to receive mode
I get as close as 007 - is this normal or indicating a problem?
next question:
On page 17 of the assembly manual at this point:
------
Go into TUNE mode briefly. At 5 watts, the voltage should be between 3 and
4 volts. If it is much
lower or higher than this, you probably have a wiring error in the SWR
bridge. Remove the KAT2 control
board from the L-C board and check the wiring of T1. Make sure T1's leads
are properly stripped.
------
I have a reading of only 2.4 V. I checked the T1 wiring but do not see a
mistake. Should I go on and add R6 or should I remove T1 and check it
outside the board?
