AM Tuning & Listening Tips

Most portable radios including the Sonido Radio have an internal AM antenna. Best performance is achieved when the radio is swiveled on its base for maximum signal pickup from the transmit- ting tower. This same technique can be used to help nullify unwanted signals or radio noise. Experimentation is the best way to see how it works for you.

Daytime reception is limited to about 300 miles maximum because you can only receive the signal directly from the trans- mitter 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: http://www.nrcdxas.org
