[Hallicrafters] SX-130 Poor Sensitivity Fix

[Wj5mh at aol.com]

I've been having an intermittent receive  sensitivity problem with my SX-130, 
and last weekend I finally got around to  doing some detective work.  The 
electrolytic's and some resistors were  replaced a couple years ago, but this 
problem started late last fall.  I  figured that since it was intermittent, the 
problem would be a poor connection  in the front end, but after some probing 
with a diddle-stick, the problem was  found to be a defective .01 disk cap (C27) 
at T1.

It took a couple hours  for the problem to show up, but once it started to 
drop out, it didn't take much  pressure on the cap to duplicate the problem.  
Yup, I guess disk caps can  go bad.  B+ to the plate of the mixer stayed about 
the same, so I'm going  to assume the cap was opening up.

Had this problem not been intermittent,  one could have thought that this 
receiver was just a little on the deaf  side.  Yes, some signals would push the 
S-meter to 10 over S-9, but with a  good cap these same international 
broadcasters would push the meter to 60 over.
