[R-390] RF to IF cables

[Barry]

A while ago, I sold some small lengths of the coaxial cable used to replace
the interconnecting cables in the R930A to members of this list.  I replaced
the PTO cable with some of it and it worked great.

Today, I finally pulled the RF deck on the current project to look for any
troublesome components (it doesn't "hear" as well on some bands and I'm not
sure what the problem is).  I found one high resistor (over 100k for an 82k
value) and replaced the bypass capacitor in parallel with it.

I then decided I would tackle the cable replacement and found it's not all
that difficult.  I removed the connectors and soldered a piece of small
(22?) gauge wire to the end of the old coax's braid.  I tried to pull it
through in one operation, but found it was easier to pull it through the
duct and lacing first and then feed the cable back through the hole to the
top side.  All that's left now is connecting the ends to the output
transformer and resoldering the mini-BNC connectors.  It really wasn't that
hard to do.  Even the old metal cable markers will slide nicely back on the
new coax.  It should look good when I'm finished with it.

After this, I need to replace the cables in my Motorola as they are in worse
condition than these were.  Maybe someday I'll get all this done...

Anyone else try this yet?
