something like MIX31, If you bought the ones from Radio Shack I think they

I, like the others who've checked in here, have put ferrites on every single

another approach might be to UN-plug as much stuff as you can from the radio,
and see if the problem goes awaymy experience with ferrites has been 'get
the big ones'.. so you can put more than one turn through them. remember ' N
squared ' ??...and, like others, have found 31 mix
I will try to unplug what I can. I have the speakers, ptt / din plug and amp

Yes I'm familiar with the mix 31 large, that's the way to go.
I've never had an issue with 20m feed line, but can add another piece of coax
to see.
Stand how its only on 20m.
Thanks for the reply.

To make things worse, every situation differs somewhat. When I used a 5-W
transmitter, I had no RFI problems (one ground rod). Changed to a 100-watt ICOM
IC-7000, and everything went nuts. I added two more 8-ft. ground rods and a few
ferrites, and the problem was mostly solved. The coax line

Steven,
Depending on where the shack ground is, it may be MORE important do
have a short ground ( no longer than the length of the firewire cable)

I had the same issue at first. I now can run full 1.5kw with no issues. The
trick is to think simple (see below).
One thing that is almost always overlooked is equipment placement. Put

I went roving this weekend during the September ARRL VHF contest

First off, the flex1500 is so valuable for spotting adjacent QSOs and

and 222 using a M2 222 transverter.

Replacing the firewire cable that came with the radio with the one from

Just changing the cable cured my QRO RF feedback problems.
