I had terrible rfi with my 590 and my windom which is fec with coax and a
4 to 1 ballun. Oddly enough, the 2000 wasn't bothered. I bought two line
isolators, one behind the radio and the other on the output of the amp.
Absolute magic, rf gone!!! Here is where I got mine. I think they are
called B2KLISO
Coaxial in-Line isolator, 160 TO 2 Meters (1.5 to 175 MHz) LINE ISOLATOR,
easily
handles 3000 watts.
