[ICOM] Icom and AM broadcast overload

[Ed Yeary]

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?
