Thanks for the replies.

I have already wound the AC input cord with chokes a few months ago, and it seemed to make a bit of an improvement.(2 s-units)

The shorter DC cable made a whale of a difference. Like 7 S-units.

Yes, its a switching supply, Alinco DMV-330. Has good ratings on EHAM for not producing noise, but I am assuming the longer power cord was a great pickup antenna for what noise there was.

Anyway, if this info helps someone else with their issues, that's what we are here for.
