The following suggestions will help you care for the PRO-2026 so that you can enjoy it for years. Keep the scanner dry. If it does get wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the product to work improperly. Use and store the scanner only in normal temperature environments. Extreme temperatures can shorten the life of electronic devices and distort or melt plastic parts. Keep the scanner away from dust and dirt, which can cause premature wear of parts. Wipe the scanner with a dampened cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the scanner. Modifying or tampering with the scanner's internal components can cause a malfunction and might invalidate the scanner's warranty and void your FCC authorization to operate it. If your scanner is not operating at it should, take it to your local Radio Shack store for assistance. -------------------------------------------------------------------------------PRO-2026 (200-0148) Features Faxback Doc. # 8436 Your new Realistic PRO-2026 100-Channel Mobile Programmable Scanner lets you in on all the action! The PRO-2026 gives you access to more than 30,000 frequencies used by police departments, fire departments, ambulances, aircraft, ham radio operators, and transportation services. You can store up to 100 frequencies into your scanner's channels, and you can scan and change your channel selection at any time. The secret to your scanner's ability to scan so many channels so easily is its custom-designed microprocessor-a tiny, built-in computer. The microprocessor also gives your scanner these special features: Service Search-lets your scanner scan the frequencies allocated to the police, fire, air, weather, or marine services so you can listen to the services you prefer, even if you do not know the frequencies. Two-Second Scan Delay-helps you keep from missing replies on a channel while you are scanning. Lock-Out Function-limits the scan by skipping over a specified channel or group of channels. Five Memory Banks-let you group channels so that you can easily scan related frequencies, such as the various frequencies used by services in different cities. Priority Channel-instantly tunes the scanner to a selected channel whenever there is a transmission on the frequency. Monitor Memory-lets you save a frequency located during a frequency search so you can easily store it in a channel. Your scanner covers all of these bands: *....................29-29.7 MHz (10-Meter Ham Radio) *............................ 29.7-50 MHz (VHF Lo) *.......................50-54 MHz (6-Meter Ham Radio) *..........................108-136.975 MHz (Aircraft) *...........................137-o144 MHz (Government) *....................144--148 MHz (2-Meter Ham Radio) *................................148-174 MHz (VHF Hi) *............................406-420 MHz (Government) *.............................420-450 MHz (Ham Radio) *.................................50-470 MHz (UHF-Lo) *................................470-512 MHz (UHF TV) *...........................806-823.9375 MHz (UHF Hi) *.......................851.0000-868.9375 MHz(UHF Hi) *...........................896.1125-956 MHz (UHF Hi) (RLR-10/14/93) -------------------------------------------------------------------------------PRO-2026 (200-0148) A General Guide to Scanning Faxback Doc. # 7923 BIRDIES Birdies are frequencies your scanner uses when it operates. These operating frequencies might interfere with broadcasts on the same frequencies. If you program one of these frequencies, you hear noise on that frequency. If the interference is not severe, you might be able to turn SQUELCH clockwise to cut out the birdie. The most common birdies to watch for are listed below. Birdie Frequencies 31.050 MHz 32.400 36.225 41.400 46.575 51.750 MHz MHz MHz MHz MHz RECEPTION NOTES 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 condition. This type of reception is unpredictable but often very interesting! GUIDE TO THE ACTION BANDS With a little investigation, you can find the active frequencies in your community. We can give you some general pointers on finding these frequencies and you can take it from there. Please use caution and common sense when you hear an emergency call. Never go to the scene of an emergency. It could be very dangerous. Find out if there is a local club that monitors your community's frequencies. Perhaps a local electronics repair shop that works on equipment similar to your scanner can give you frequencies used by local services. A volunteer police department or fire department employee can also be a good source for this information. As a general rule on VHF, most activity concentrates between 153.785 and 155.98 MHz and between 153.73 and 159.45 MHz. Here you find local government, police, fire, and most other emergency services. If you are near major railroad tracks, listen between 160.0 and 161.9 for signals. In some larger cities, there has been a move to the UHF bands for emergency services. Here, most of the activity is between 453.025 and 453.95 MHz and between 456.025 and 459.95 MHz. In the UHF band, mobile units operate between 456.025 and 459.95 MHz and between 465.025 and 469.975 MHz. A repeater picks up the mobile units' transmissions on one frequency, then rebroadcasts (or repeats) the transmission 5 MHz lower, but at a higher power level, than the mobile units (that is 451.025-454.95 MHz and 460.025-464.975 MHz). This means that if you find an active frequency inside one of the mobile unit's frequency spreads, you can look 5 MHz lower to find the repeater frequency. A system called trunked radio lets several services use the same set of frequencies in the 800 MHz band without interference. Several frequencies are allocated to two or more services (like fire, police, and water departments). As each service transmits, a separate control signal activates other radios in the same service, so that only that service hears the transmission. The frequency is selected as soon as the unit begins to transmit, and could be any one of the allocated frequencies. One very useful service is the National Weather Service's continuous ....

You might be interested in finding more out about radio. This mixing process primarily gives us the two original frequencies.7 MHz. The one radio may simply not be "tricked" into picking up an image! This rejection of undesired signals is one reason that a triple-conversion receiver costs more than a similar dual-conversion model. and their difference. Because nothing is perfect. we might be able to tune to a frequency 21..000 2780 kHz / 1000 = 2. because the triple-conversion radio's 1st intermediate frequency is quite high. most tune to a frequency by mixing that frequency with another (local oscillator) frequency which is slightly different.
