CAN DISTANT AM/FM BROADCAST STATIONS BE RECEIVED?

FM is strictly for local stations. Daytime AM stations usually have a maximum distance of 50-100 miles. At night, AM broadcast signals can sometimes be heard over much greater distances, hundreds of miles away.

HOW IS IT THAT BROADCASTS FROM AROUND THE WORLD CAN BE HEARD ON A SHORTWAVE RADIO?

Shortwave radio can be heard around the world because of the earth’s ionosphere. Think of the ionosphere as a cloud-like layer enshrouding the earth at an altitude of 140-250 kilometers (90-

160)miles). It consists of electrons and ions, the density of which are governed by the sun and the earth’s geomagnetic forces. Radio waves virtually bounce their way around the earth, bounc- ing off the ionoshpere, back down to earth, often repeating this process several times. The low angles at which this takes place enable the radio waves to travel great distances with each bounce. This whole process is called radio wave deflection and ionospheric propagation.

HOW CAN I DETERMINE IF AN OUTDOOR ANTENNA WILL HELP?

While inside your normal listening environment, tune in a rela- tively weak shortwave signal. Staying tuned to this signal, step outside and away from your building. If the signal strength increases significantly, an outdoor antenna will help considerably. If there is little or no improvement in signal strength, an outdoor antenna will help; however, the amount of improvement will depend on the type of antenna used. If you have questions about outdoor antennas, call Grundig technical support.

WHAT TIME STANDARD IS USED IN SHORTWAVE BROADCAST SCHEDULES?

Since there are many different time zones around the world, it would be impractical for shortwave broadcasters to give broad- cast times for each separate time zone. To simplify matters, they list their broadcast schedules
