GE MASTR II Intermittent Sensitivity
Problem and Fix
By Joe Szczech, Jr.  K1IKE

I just thought that I would share this frustration with you all.

I purchased a repeater receiver off of eBay and tested it out.  Poor receiver sensitivity, ugggh!  This was suppose to be tested and working fine!  After a few hours of playing around, I decided to use my carpenter friend/repeater owner's troubleshooting technique.  (He shall remain nameless).  Several well placed taps and I found a cold solder joint.

Here are photos.  They are thumbnails so clicking on the images will open a new picture in high resolution:

I take back all the bad thoughts that I had about the eBay seller.  He probably never even knew it had a problem.  The irony of it all is that I had the same problem years ago and forgot about it.  I thought I would post it here so you could see the problem and I wouldn't forget about it!

Old age takes it's toll.....
