My AN/GRC-46C Restoration Page

In April, 2010 I discovered an AN/GRC-46 for sale in Delaware.  I had seen it a year earlier but did not do any inspection at that time so I was basically buying it sight unseen, on the phone.  I did not know the model but it turned out to be a "C", the last produced in 1963+/-.  I was assured on the phone everything was in there and that the owner powered everything up a few years ago.  So, I bought it and brought it home.  During inspection at home I discovered several cables were missing with others that had the connectors cut off and unusable, the RTTY printer was the wrong one and there were many holes drilled in the shelter for who knows what.  Also, the roof leaked and lots of dents in the shelter skin. The T-195 had a tag on it saying "blows fuses" and the dog bone to the R-392 was missing.  No way anyone "powered it up"!  Caveat emptor now had a new meaning!

OK, I own it so what to do with it?  I stripped it out and began to restore it to "like new" condition.  I already have a TT-98 to replace the wrong one so I made a list of other items I would need.  A few of the missing cables were found at a military radio/truck show and plans are now made to find the remaining parts. The following pictures are my progress on this project.

This shelter was placed on my M-37 in fall, 2013.
