Kim,

        No it's a good idea. I just plugged my TECSUN PL-310 portable shortwave 
into my HF antenna (HyGain DX-88) when I do that I hear the noise on the 
portable...

        I do not have another HF antenna, other than a 14 AVQ in pieces in my 
garage.

        Keep the ideas coming!

73,
Gary "Joe" kk0sd

It's odd that you can't hear it on your portable rx. That made me
curious: What if this is something internal to your '847? Have you tried 
pulling your '847 and listening on a different receiver using the same antenna? 
If you have, do you still hear the noise? It's a long shot, but...
