Hi Mark
Sounds like you may need to install some Mix 31 and Mix 43 torroids to
start to knock the RF down. Since it is worse with the Amp on, it seems
related to RFI.
I would start with each and every power lead and then work on the audio
leads.
Google YCCC and Choke and you will find the PDF that Chuck W1HIS assembled.
You will find it very informative.

I have been trying to integrate a Behringer DEQ2496 into my audio chain
with
my Flex 5000A. My shack is on the second floor of my house so RFI is a
constant problem. Using only my Behringer Xenyx802 mixer board and my 5000A
there are no major RFI problems. I have isolated the 802 from the ballanced
line input on the 5000A with a Jensen JT-11P-1 audio transformer. When I
add
the DEQ2496 I get an RFI spike at about 2~3 Hz. I can see the spike on both
the 5000A panadapter and on an oscilloscope tapped at my 811H amp output. I
have tried various audio isolation techniques but no joy. The spiking is
the
most pronounced with the amp on. Has anyone encountered this issue and
solved this problem ? if so please advise.
