Do a Google search on CCrane. They sell a couple of antennas that should
help you out. One is the Select-A-Tenna. It is a loop such as Jim referred to. It works quite well. Improves reception dramatically and is directional with good nulls to kill the noise. The second mounts outside and runs into the radio via cable. There is a ferrite bar that attaches to the radio so no connection required. "Jim" wrote in message ... I say it is worth the try. The interference may not be directly from the DSL modem itself, but leaking from the cables. If I recall correctly, the DSL signal (at least here in the USA) is a couple of watts somewhere aorund the AM broadcast band. So you essentially have a 2 watt transmitter pumping out wide-band trash within a few meters of your receiver. There used to be a 'AM signal booster' available. All it consisted of was a coil of wire about 8 inches in diameter witha variable capacitor for tuning. You just placed it next to your AM radio and the coil coupled into the built-in loopstick antenna. Jim N8EE |

Jim and others. I've played around with ADSL modem location, orientation
etc, and whilst it's the cause of the noise, it's the low signal strength at the radio which is what I have to fix. If the radio is right next to ( inches) the modem, and is oriented optimally, the interference is minimal. I'd hoped for a home grown rather than a commercial solution - but my AM aerial knowledge faded once I stopped playing with crystal sets and battery powered valve radios some decades ago. Also CCrane isn't well represented in the antipodes. David "CW" wrote in message ... Do a Google search on CCrane. They sell a couple of antennas that should help you out. One is the Select-A-Tenna.

OK. The Select-A-Tenna is nothing more than a coil of wire and a capacitor.
Do a Google search on medium wave loop. AM loop, ect. There are lots of plans out there. Yes, they really do make a dramatic difference. "David Flew" wrote in message ... Jim and others.
