AM TUNING & LISTENING TIPS
The CCRadio is made for distant or weak AM signal listening. Daytime
reception is limited to about 300 miles maximum because you can only
receive the signal direct from the transmitter site. You may receive AM
stations thousands of miles away at dawn, dusk and at night, depending
on the time of year and atmospheric conditions. The ionosphere is a
layer of ions above the earth. At night it slows and congeals into a giant
mirror and can reflect radio waves back to the earth; allowing you to
receive signals much farther away than during the day.
Distant listening is called DXing. One club that is devoted to DXing is
National Radio Club at: PO Box 164, Mannsville, NY 13661-0164. They
maintain a website at:

Most portable radios including the CCRadio have an internal AM anten-
na. Best performance is achieved when the radio is swiveled on its base
for maximum signal pickup from the transmitting tower. This same tech-
nique can be used to help nullify unwanted signals or radio noise.
Experimentation is the best way to see how it works for you.
The CCRadio has two external antenna terminals for AM. If your recep-
tion is better outside, for a quick and easy antenna use 50’ of insulated
wire attached to one terminal and a ground to the other terminal. Safety
directions and precautions from your antenna supplier should be
followed to prevent injury from lightning or any accident.
