Hi Guys
Thanks to those that have responded to the previous message. A service
manual has been located and that will help if further investigation needs to be
made.
What I have found is that the driver transistor 2SC2538 on the PA board
has very touchy SSB tuning. (Under bottom cover, toward the back) There
are 2 tuning caps on the collector. The TC02 variable is VERY fussy and
TC03 less so. I have found that my SSB output can be improved greatly by
careful adjustment of these two. I suffer some loss of output on FM, but no
big deal. The output is now very constant regardless of mode at about 1 1/2
watts (no amp) ...
Thanks again
