problem of power dropping to zero was on all bands which seemed to eliminate
the filter board. The problem had happened once a year or so ago when I
posted a question relating to "Lo Po" display (I have the KAT2) but th

Q6 is quite husky, so I would not suspect the device itself. Check R50
for good soldering, also look at the schematic Sheet 4 of the RF Board
