A note about HD RadiosĪll Prairie Public stations broadcast in HD and analog - an HD radio can pick up both. Getting an HD (hybrid digital) receiver eliminates this problem also. The solutions are the same as described above - moving the radio or attaching an antenna. Adjacent channel interference occurs when another station is on the next frequency. Since the echo is delayed, the two signals interfere with each other. Multipath distortion happens when your radio is receiving the signal, but then also picks up an “echo” from a hill or a building. An external TV-type antenna should be pointed at the transmitter.Įliminate multipath distortion and adjacent channel interference A folded dipole (T-shaped) antenna should be broadside to the transmitter. You can buy outdoor antennas made for FM, but TV antennas work very well - and there are a lot of old ones available, thanks to cable and satellite. The best reception can be attained with an outdoor or attic mounted antenna.Excellent antennas are available at a range of prices, from $50 to $400. Powered FM antennas work even better - they are available at electronics stores and on-line.Crane for an inexpensive indoor attachment. Our director of radio recommends the “FM Reflect-2 Dipole Antenna” from C. These are sold at many electronics and hardware stores. They work best if you tack them up to the wall, the higher the better. Better than that can be the T-shaped flexible wire antennas known as folded dipoles. FM operates at the same range of frequencies as television, so television “rabbit ears” can help.They’re usually labeled “ant.” Some radios with telescoping antennas are set up so that you can disconnect that one and attach a different one. Some smaller radios don’t allow this - look for a couple of screws or clips on the back. If you have a radio with a telescoping swivel antenna, experiment with moving it around.
