Well, if you have excess coax in the system, you could try winding the 
choke anywhere and see if it helps.  You could buy a line isolater from 
   a supplier and  try putting into the line wherever convenient.

I loaded up on ferrite snap on beads a few years ago from All Electronic 
Supply.  Prices have gone up, and they may carry different sizes at 
different times, but look here:

   In my case, I clamped coax in and out to the amp, control and alc 
lines, and a.c. line.

Good luck, Steve KW3A
