I open this discussion with an admission that I am left handed...so I do
my best but sometimes things get done in a strange manner.
After reports that I have some warble/distortion on the SSB signal of
my Argosy 525, I have asked a few questions and read a bit as well.
Consensus is that having either the driver or final bias mis-set can
cause the symptoms I have had described to me. So I figure a good way
to start was to check the bias settings.
With the owners manual open, I look for the final board and discover
that it resides on the back panel facing the final amp board. so I only
have to remove 3 more screws holding a spacer - shield? covering the top
area where the two boards sit, between the rear panel and the heatsink.
I thought...not a problem. The spacer is held by two sheet metal screws
and a bolt in the center. Of course, the screws are removed easily. As
a ham, I do own a set of miniature wrenches and socket set. If only it
were that easy. The bolt only protrudes a bit...maybe a 1/16 if I am
lucky. Of course, the bolt turns with turn of the nut, and is too short
to be grabbed by my miniature needle nose pliers. So here I sit asking
for advice.
One thought that came to me was that maybe the rear rear panel/heat sink
might be removable without too much pain. I am sitting on pins and
needles (or maybe just sheet metal screws) and hoping that some else may
have hit this roadblock and come up with answer or two.
Thanks for reading this and Big thanks if you can offer some advice or
solutions.
