[R-390] RF decks

Fri, 5 Apr 2002 09:46:23 -0500

John, if your heart is a-pounding about the R-390A's RF deck, try pulling
and re-installing a completely out-of-sync RF deck from an R-390 (non-A). In
actuality, it's easier than it sounds. It's all common sense when you get
down to it, and Dave Medley and others offer loads of encouragement. I did
mine, without the little green gear!

Good luck!

Subject: [R-390] Re: Wiring question

Thanks for all the help regarding the wiring for the Carrier Level adj. pot.
I should have been able to figure it out, but I tend to work in high anxiety
mode--anticipating that I will do, or have done, something which can not be
easily repaired.  It affects one's clear thinking--as does the damn memory
fade.

Any way, I worked up the courage to replace the paper caps in hopes of
curing an intermittant noise problem.  The audio chassis went well, then the
IF.  It was much tighter work, but I got them all replaced--but the noise
remained.  Breathing deeply and refreshing my memory with the R-390A video,
I removed the RF chassis.  My heart is still pounding!!  Will I ever get
that beast back in?  I see there are 3 Black Beauties in it, so today they
will be replaced.

I also noticed that the small coaxial cables look a bit suspect--cracked
insulation.  Can those little BNC-like connectors be used again with new
cable?  Are the cables available from some enterprising soul?  Well, that's
down the road.  I'm hopeful these last caps. will do the trick.
