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.

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.

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.
