It sounds like this is happening when not transmitting

Correct .

How does the RF connector look at the antenna cable, especially the
shield connection. If you give it a good wiggle when connected does it
change what you hear?

No, it doesn't.


Are the ferrite isolators as close as possible to the power supply
cable entry on the Radio and LX7000?

Yes.


Inspect all the wiring, remove and replace any PVC insulated wire with
Tefzel insulated MIL spec wiring :-) (my real reason for posting was I
just wanted to say that).


:-))
I'll check everything you kindly suggested

thanks!
