Hi Richard,


How much power are you running when you
have the reverberation?

What type of antenna does it occur on?

What is your feedline and how do you
isolate any RF near your operating position?


I have had success with clamping ferrite
at the antenna/feedline point and
feedline/home point.

I still have some RF in the shack with my
long wire antenna, but that one has lots
of feedline radiation and the tower is
right outside my shack, so it's tough to
be out of the RF field.

I have been plagued from day one with intermittent reverberation or echoing on 
the transmitted signal from my 5000a.  Despite hundreds of software adjustment 
experiments and putting ferrite snap beads both ends of every cable attached to 
the 5000a I continue to be plagued and embarrassed by this problem on the air 
and ridiculed by my ham friends.  I also searched the knowledge base for a 
solution but the only related article is based on the SDR-1000, and I'm not 
sure it applies.  Are any other 5000A  owners experiencing this?  What did they 
do to slay this demon?
