Hi Group,
Can any one help on this anoying matter please?
I have an DX-394 in a room where Broadband cable for the Internet was
installed, since that day I have interferance on my DX, Long wave and
Medium wave. Shortwave bands dont seem to get any where as near
interferance.
Since I like to do a lot of Medium DX this has become intollerable.
Has any one any ideas on what I can possibly do about this?
I have tried a loft antenna but I get the same problem.
I am using no earth cable.

The antenna is an outside 50' long end fed. I have a co-ax that I can
use but will it be worth the trouble?

TIA,
Mike......

Try grounding, shielded lead-in or anything else you can think of. I doubt
anything will reduce the interference much. But it should add credibility
to the one thing which may help. Written complaints. I don't know who in
the UK takes RF interference complaints, but I'm sure you'll get an answer
here. The BBC should also have an interest. Also, if your neighbors are
having interference problems, encourage them to complain.

You could also post your question to the UK radio amateur groups.

Mike, I doubt the source of the interference is the broadband cable itself
but more likely the hardware attached to it. That's good news because
getting your antenna far away from the hardware should help a lot -
especially using shielded transmission line as Frank suggests. The bad news
is that the DX-394 has a built-in ferrite rod LW/MW antenna so you'll need
very long, bendy arms to move the antenna far away! Some of us have shielded
our DX-394's to great advantage. I've even gone to the length of removing
the ferrite rod antenna. For more, visit www.mods.dk and the DX-394 user
group at http://groups.yahoo.com/group/RADIOSHACKDX394/ .

I think you've got it. I sorta went into "BPL mode" and overreacted. A
cable system shouldn't be a major RFI source. But since it's a new
installation, it's worth checking to be sure the system's shielding is
working properly. The interference hot spots can be sniffed out with a
small hand held radio tuned to MW or LW.
