Separate the supply from the radio , put in a new fuse, jumper position 1
and 2 on the end of the power cable, a heavy short piece of wire, and plug in
the supply. If the fuse does NOT blow, looks like you have a

Hi Garey ,and all the others who had thoughts, on my problem
The problem is solved. Put the R-4 on the bench, tightened ALL the

OK. So what you had was a bad ground connection, probably the shield
connection for the ANT jack, that was allowing the shield of the short
coax to 'float', and the center conductor to essentially be a short antenna.
As Richard said, there may have been signals coming from the R-4
