The most important element for beginning DXers is to get to know the
dial. Spend a few hours scanning up and down the dial both during the
day and at night. At night, many of the clear-channel 50kw stations,
particularly the non-directional ones, should be easy to hear. Learn
all the local stations. Find out which ones sign off at sunset, which
ones go off late at night, and which stay on all night. This will affect
which distant stations can be received. If you have a local station on
all night, you shouldn't expect to hear another station on that
frequency without some tedious nulling. Experiment with radio placement.
As you slowly turn the radio, observe its directional characteristics.
The Superadio III will receive signals coming from the front and back of
the set the best, and attenuate the signals coming in `off the side' of
the set. You can use this to your advantage and log several stations on
a single frequency.
By all means, keep a log of all new stations you hear; someday you'll be
glad you did! Better yet, keep it on the computer; that way you can
share it with others on the net. After a few months of listening; you
should have a list of 200-300 stations you've heard. Most of these will
be your `regulars', audible almost daily. Beyond that, you can hunt for
the rarer stuff. Try for all 50 US states (very, very difficult), or 20
countries (fairly easy in most locations). Within a few years, you'll
likely have heard a thousand or so stations and have a very interesting
logbook. Here's a `beginner's target list' of widely heard clear channel
AM stations to start you out; from most locations in North America you
should be able to hear all but four or five of these fairly easily.
