I recently transferred some of my station to another operating position. I 
am now having
problems with AM broadcast overload up and down the HF bands. First my IC 
706mkIIG and now
my 746 pro are being overloaded. I don't live all that close to the AM 
transmitter. It's
at least 3 -5 miles away. At first I thought this was due to my 706 having a 
connector
problem but that has been fixed and my 746 is FB after getting it back from 
the radio
doctor. I have tried Ferrite beads and may need to add some more and I will 
try to improve
my grounding but other than this are there some more things to try?

ED: I know that you believe you have checked all connectors and connections, 
but it sounds to me that you may have a good case of RF rectification  from 
the BC station going on somewhere in your station setup. The clue being 
after you relocated a part of your station. AS crazy as it sounds, double 
check and clean all connectors and connections, including any antenna 
switches. It could be at the coax to antenna connections itself. Assume 
nothing. BC overload, not very likely, unless you are within a mile or two 
of a 50 Kw station. Good luck, Larry K4LXV.
