PRO-2042 Programmable Scanner (200-0464) Guide to Scanning Faxback Doc. # 31535 Reception of the frequencies covered by your scanner is mainly "line-of- sight." That means you usually cannot hear stations that are beyond the horizon. During the summer months, you might be able to hear stations in the 30-50 MHz range located several hundred or even thousands of miles away. This is because of summer atmospheric conditions. This type of reception is unpredictable but often very interesting! GUIDE TO FREQUENCIES National Weather Frequencies 161.650 MHz 162.425 MHz 162.475 MHz 162.550 MHz 161.775.

These operating frequencies might interfere with broadcasts on the same frequencies. If you tune one of these frequencies, you hear only noise on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. These are the most common birdies to watch for: 25.800 MHz 27.640 MHz 28.125 MHz 30.405 MHz 32.145 MHz 33.170 MHz 36.160 MHz 40.180 MHz 41.460 MHz 44.195 MHz 48.045 MHz 48.215 MHz 52.235 MHz 54.750 MHz 56.345 MHz 64.275 MHz 68.305 MHz 72.320 MHz 76.340 MHz 80.200 MHz 80.360 MHz 80.600 MHz 84.360 MHz 108.4825 MHz 112.500 MHz 116.525 MHz 120.5375 MHz 123.375 MHz 144.135 MHz 144.645 MHz 152.655 MHz 155.625 MHz 184.830 MHz 192.860 MHz 200.900 MHz 212.950 MHz 220.950 MHz 224.960 MHz 225.000 MHz 233.050 MHz 237.0125 MHz 241.075 MHz 249.1125 MHz 265.1875 MHz 299.5625 MHz 311.400 MHz 343.600 MHz 362.000 MHz 387.000 MHz 412.000 MHz 421.800 MHz 425.9125 MHz 466.250 MHz 467.250 MHz 490.375 MHz 491.375 MHz 772.200 MHz 773.400 MHz 774.600 MHz 907.5625 MHz 820.400 MHz 821.600 MHz 822.800 MHz 906.3125 MHz 1022.800 MHz 908.8125 MHz 1004.250 MHz 1008.600 MHz 1013.000 MHz 1090.400 MHz 978.500 MHz 1055.125 MHz 1068.4375 MHz 1074.600 MHz 1166.200 MHz 1025.6875 MHz 1117.6875 MHz 1152.750 MHz 1164.625 MHz 1281.250 MHz 1113.000 MHz 1186.800 MHz 1188.375 MHz 1196.125 MHz 1182.4375 MHz 1227.000 MHz 1227.500 MHz 1251.875 MHz 1200.250 MHz 1271.950 MHz 1264.9375 MHz NOTE: Depending on the temperature of some of the scanner's components, you might hear birdies on frequencies slightly above or below the frequencies listed here.
