[R-390] R-390 Problems

[David C. Hallam]

SO JUST SHOOT ME!

After several days of bench work trouble shooting trying to locate a loss of
sensitivity problem with my R-390 and introducing several new ones  by
screwing up the alignment that had to be corrected, I came to the conclusion
that I couldn't find anything wrong with the receiver.  It passed the
sensitivity and selectivity tests with flying colors.  Back to the drawing
board.

I put the receiver back into the rack and hooked up the coax.  Wait a
minute, the reception is changing as I wiggle the coax.  This was a ready
made up RG-8X jumper that I purchased at Radio Shack just before the
problems started.  Close examination reveled a bad connection in one of the
PL-259's.  There must be a moral in here somewhere.
