31 Assigning a CTCSS Tone Frequency to a Channel You can specify the CTCSS tone fre- quency you want the scanner to de- tect on a specific preprogrammed channel. 1. Select the channel number that has the frequency you want to assign a CTCSS tone frequency to. 2. Press PROGRAM. PGM appears on the display. 3. Press CTCSS. CTCSS and 00.0 appear on the display. 4. Press FREQ/CHAN-LOCK until FREQ appears on the display. 5. Using s, t, or the rotary tuner, choose the CTCSS frequency. The channel number flashes on the display. Note: Turn the rotary tuner clock- wise to step up the displayed tone frequency. Turn the rotary tuner counterclockwise to step down the displayed tone frequency. 6. Press E. The channel number stops flashing. 7. Press MANUAL. The scanner dis- plays the channel and frequency. 8. To turn on CTCSS for that chan- nel, press CTCSS. The scanner’s display alternates between the frequency and the CTCSS tone frequency. Changing or Deleting a CTCSS Tone Frequency for a Channel 1. If CTCSS is not displayed, press CTCSS. The scanner displays CTCSS. 2. Select the channel number that contains the CTCSS tone fre- quency you want to change or delete. 3. Press PROGRAM, then CTCSS. 4. Using s, t, or the rotary tuner, select 00.0 to delete the CTCSS tone frequency or select another CTCSS tone frequency to replace the current one. 5. Press E. 20-418.fm Page 31 Wednesday, August 4, 1999 12:42 PM
32 A GENERAL GUIDE TO SCANNING Reception of the frequencies covered by your scanner is mainly “line-of- sight.” That means you usually cannot hear stations that are beyond the hori- zon. 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 con-ditions. This type of reception is unpre- dictable but often very interesting! GUIDE TO FREQUENCIES National Weather Service Frequencies Ham Radio Frequencies Ham radio operators often broadcast emergency information when other means of communication break down. The following chart shows the voice frequencies that you can monitor. 161.650 MHz 162.425 MHz 162.475 MHz 162.550 MHz 161.775 MHz 162.440 MHz 162.500 MHz 163.275 MHz 162.400 MHz 162.450 MHz 162.525 MHz Wavelength Voice Frequency (MHz) 10-meter 29.000 29.700 6-meter 50.100 54.000 2-meter 144.100 148.000 1 1/4-meter 222.000 225.000 70-centimeter 420.000 450.000 33-centimeter 902.000 928.000 20-418.fm Page 32 Wednesday, August 4, 1999 12:42 PM
33 Birdie Frequencies Birdies are frequencies your scanner uses when it operates. These operating fre- quencies 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. Here are this scanner’s birdie frequencies that you might want to watch for: To find the birdies in any receiver, begin by disconnecting the antenna and moving it away from the receiver. Make sure that no other nearby radio or TV sets are turned on near the receiver. Use the search function and search every frequency range from its lowest frequency to the highest. Occasionally, the searching will stop as if it had found a signal, often without any sound. That is a birdie. Make a list of all the birdies in your scanner for future reference.29.4900 114.6875 147.4550 405.6000 29.4950 117.9625 147.4600 416.0000 31.2000 124.5250 150.9100 417.1000 36.0450 127.8000 155.1050 456.9260 52.0000 131.0750 156.0000 469.5000 52.4300 134.3500 228.4625 813.4000 108.1375 135.2000 230.5625 820.1125 108.8125 137.6250 232.1000 940.9000 111.4125 140.9050 398.2375 993.5000 114.4000 144.1800 20-418.fm Page 33 Wednesday, August 4, 1999 12:42 PM

35 Primary Usage As a general rule, most radio activity is concentrated on the following frequencies: VHF Band UHF Band Note: Remote control stations and mobile units operate at 5 MHz higher than their associated base stations and relay repeater units. Activities Frequencies (MHz) Government, Police, and Fire Emergency Services153.785–155.980 158.730–159.460 Railroad 160.000–161.900 Activities Frequencies (MHz) Land-Mobile Paired Frequencies 450.000–470.000 Base Stations 451.025–454.950 Mobile Units 456.025–459.950 Relay Repeater Units 460.025–464.975 Remote Control Stations 465.025–469.975 SPECIFIED INTERVALS :Frequencies in different bands are accessible only at specific intervals. For example Note: Your scanner automatically rounds the entered frequency down to the closest valid frequency. For example, if you try to enter a frequency of 151.473, your scanner accepts it as 151.470.

40 TROUBLESHOOTING If you have problems, here are some suggestions that might help. If none of these suggestions help, take yourscanner to your local RadioShack store for assistance. PROBLEM POSSIBLE CAUSE REMEDY Scanner is totally inop- erative.No power. Make sure you plugged the scanner into a work- ing AC or DC outlet. Scanner is on but will not scan.• SQUELCH is not cor- rectly adjusted. • A channel has been manually selected.• Adjust SQUELCH clockwise. • Press SC AN. While scanning, the scanner locks on fre- quencies that have an unclear transmission.“Birdies.” Avoid programming fre- quencies listed under “Birdie Frequencies” on Page 33 or only listen to them manually. Rotary tuner does not work.Rotary lock is turned on. Press LOCK until FREQ or CHAN appears on the display. 20-418.fm Page 40 Wednesday, August 4, 1999 12:42 PM
