Realistic PRO-41 Direct Entry Programmable ScannerRealistic PRO-41 Direct Entry Programmable Scanner <BR>Police Scanner / Communication Receiver == Description ==The Realistic Scanner Pro-41 is a police and emergency scanning radio that receives UHF/VHF high and low frequencies on 10 channels and is fully programmable. The scanner also has a built-in earphone jack and squelch control. Programming the Realistic Pro-41 takes a few keystrokes on the scanner's keypad and a few minutes. [[File:RealisticPRO-41Scanner.jpg]] == Review ==From the inside, The Realistic PRO-38 and PRO-41 and the Uniden Bearcat 50XL are almost identical. They are 10 channel scanners. These were simple low end scanners for their day, very affordable. After 15 years and the removal of corroded leaky batteries, the scanner still works like new. It must have been well built. For modern use, although it does not do 2.5 khz stepping, it still partly receives [[GMRS]] and [[FRS]] transmissions, except limited due to being slightly off frequency. You can enter the rounded frequency and the agile tuner will receive due to the transmission spectrum spread. This scanner is not capable of listening to AM VHF aviation. This is a distinctive shortcoming that was relevant from the date of manufacture. Overall, this scanner is of very limited relevant purpose today.=== Birdies ===Birdies are frequencies your scanner uses when it operates. These operating frequencies might interfere with broadcasts on the samefrequencies. If you program 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. The most common birdies to watch for are listed below.Birdie Frequencies: 31.05 MHz 124.20 MHz 41.40 MHz 134.55 MHz 51.75 MHz 144.90 MHz 113.85 MHz 155.25 MHz===Reception Notes===Reception of the frequencies covered by your scanner is mainly "line ofsight". That means you usually cannot hear stations that are beyond thehorizon. During the summer months you may be able to hear stations in the30-50 MHz range located several hundred or even thousand of miles away.This is because of summer atmospheric conditions. This type of receptionis unpredictable but often very interesting!One very useful service is the National Weather Service's continuousweather broadcast. These broadcasts contain weather forecasts and datafor the areas around the station, plus bulletins on any threateningweather conditions. These stations use three frequencies - 162.40,162.475 or 162.55 MHz. In most areas of the country, you can receive oneof these frequencies.===A Guide To The Action Bands===With the right frequencies programmed into your PRO-Series Scanner, youcan monitor exciting events. With a little investigation, you can findactive frequencies in your community. We can give you some generalpointers, and you can take it from there. Please use caution and commonsense when you hear an emergency call. Never go to the scene of anemergency. It could be very dangerous.Find out if there is a local club that monitors your community'sfrequencies. Perhaps a local electronics repair shop that works onequipment similar to your scanner can give you frequencies used by localradio services.A volunteer police department or fire department can also be a good sourcefor this information.As a general rule on VHF, most activity is concentrated between 153.785and 155.98 MHz and then again from 158.73 to 159.46 MHz. Here you findlocal government, police, fire and most such emergency services. If youare near a railroad yard or major railroad tracks, look around 160.0 to161.9 MHz for signals.In some larger cities, there has been a move to the UHF bands foremergency service. Here, most of the activity is between 453.025 and453.95 MHz and between 456.025 and 467.925 MHz.In the UHF band, frequencies between 456.025 and 459.95 MHz and between465.025 and 469.975 MHz are used by mobile units and control stationsassociated with base and repeater units that operate 5 MHz lower (that is,451.025 to 454.950 and 460.025 to 464.975 MHz). This means that if youfind an active frequency inside one of these spreads, you can look 5 MHzlower (or higher) to find the base station/repeater for that service.===Typical Band Usage===The following is a brief listing of the typical services that use thebands you scanner can receive. This listing helps you decide which rangesyou would like to scan.These frequencies are subject to change, and might vary from area to area.For a more complete listing refer to the Police Call Radio Guide availableat you local RadioShack store.

GTR</nowiki>Frequency ConversionThe tuning of a station can be expressed in frequency (kHz or MHz) or inwavelength (meters). The following information can help you make thenecessary conversions.*1 MHz (million)=1,000 kHz (thousand)To convert MHz to kHz, multiply by 1,000:*9.62 MHz x 1000 = 9620 kHzTo convert from kHz to MHz, divide by 1,000*2780 kHz / 1000 = 2.780 MHzTo convert MHz to meters, divide 300 by the number of megahertz*300 / 7.1 MHz = 42.25 metersA Note on Image ReceptionRadios work by simple mathematics. For example, most tune to a frequencyby mixing that frequency with another (local oscillator) frequency whichis slightly different. This mixing process primarily gives us the twooriginal frequencies, their sum, and their difference. Well, the radio'sIntermediate Frequency (I.F.) filter normally passes either the sum ordifference frequency, and this is then processed into the sound we hear.Because nothing is perfect, certain "harmonics" will also get through ifthey are strong enough. For example, if a radio's I.F. is 10.7 MHz, wemight be able to tune to a frequency 21.4 MHz (2 x I.F.) above (or below,depending on the radio's design) a strong signal and hear it! This is moreevident in a double-conversion radio than a triple-conversion radio,because the triple-conversion radio's 1st intermediate frequency is quitehigh. This causes the image to be so far off frequency that it is easy toeffectively filter it out.So remember that just because a radio doesn't receive something whichanother does is not necessarily an indication of a problem. The one radiomay simply not be "tricked" into picking up an image! This rejection ofundesired signals is one reason that a triple-conversion receiver costsmore than a similar dual-conversion model.You might be interested in finding more out about radio. One goodlocation to start looking is your local public library. You might alsowish to contact the A.R.R.L., as they are an excellent source ofinformative texts on the subject.Contact: Amateur Radio Relay League 225 Main St., Newington, CT 06111-1494 USA(CD EB 2/22/00)== Operation =====Settings the Volume and squelch controls===Rotate VOLUME clockwise and SQUELCH counterclockwise until you hear ahissing sound. Then, slowly rotate SQUELCH clockwise until the noisestops. Set VOLUME to a comfortable level.If the scanner picks up unwanted weak transmissions, rotate SQUELCHclockwise to decrease the scanner's sensitivity to signals.===Using the Key Lock===Once you program the scanner, you can protect it from accidental programchanges by moving the lock SWITCH to IN. In this position, the onlycontrols that operate are VOLUME, SQUELCH, MANUAL, and SCAN.When you want to change the scanner's programming, move the LOCK switch toOUT.===Programming the Scanner===* '''MANUAL''', Channel #, '''MANUAL''', Frequency, '''ENTER'''Follow these steps to store frequencies in channels.1. Select a channel to program by pressing MANUAL, entering the channel number you want to program, and pressing MANUAL.2. Enter a frequency.: To enter the decimal, press ./CLEAR. The decimal point is displayed as a dash (-) on the display.3. Press ENTER to store the frequency.: If you made a mistake in Step 2, E appears on the display. Press ./CLEAR twice and repeat Step 2.4. To confirm the proper entry, press REVIEW. The programmed frequency appears on the display, one digit at a time.5. To program more channels, repeat Steps 1 to 3. If you want to program the next channel in sequence, simply press MANUAL and repeat Steps 2-4.Tips for ProgrammingA good reference for active frequencies is Radio Shack's Police CallDirectory including Fire and Emergency Services.We update this directory every year, so be sure to get a current copy.Frequencies in the VHF bands are in 5 kHz steps. In the UHF bands, theyare in 12.5 kHz steps. The scanner automatically rounds the frequency tothe nearest valid number. For example, if you try to enter a frequency of151.373, your scanner accepts it as 151.475.===Scanning the Channels===To begin scanning the channels, press SCAN. The scanner scans through allthe channels except the ones you have locked out. Be sure to read thefollowing sections to get the full benefit from the scanner's specialfeatures.===Locking Out Channels===You can make the scanner scan more efficiently by locking out channelsthat you have not programmed. Enter the channel number you wish to lockout, press MANUAL and then press LOCK OUT so that the LOCK OUT indicatorlights. This is also handy for locking out channels that have acontinuous transmission. You can still manually select locked outchannels for listening.To unlock a channel you have locked, manually select the channel and pressLOCK OUT so that the LOCK OUT indicator goes off.===Manually Selecting a Channel===You can continuously monitor a single channel without scanning. This isuseful if you hear an emergency broadcast on a channel and do not want tomiss any of the details - even though there might be periods ofsilence - or if you want to monitor a channel that you have locked out.To select a channel to monitor, press MANUAL and advance through thechannels by pressing MANUAL repeatedly, or move directly to a channel byentering the channel number on the keypad then pressing MANUAL. If thescanner is scanning and has stopped at the desired channel, press MANUALone time.===Automatic Scan Delay===The scanner stops when it finds a signal. It begins scanning otherchannels about 3 seconds after the signal ends. The 3-second delay givesyou a chance to receive a reply to the first signal.===A General Guide to Scanning===BIRDIESBirdies are the products of internally generated signals that make somefrequencies difficult or impossible to receive. If you program one ofthese frequencies, you hear only noise on that frequency.If the interference is not severe, you might be able to cut out the birdieby turning the squelch control clockwise. The most common birdies towatch for are listed below. 30.300 MHz 31.200 MHz 32.500 MHz 41.600 MHz 52.000 MHzRECEPTION NOTESThe scanner receives signals that are mainly "line of sight." That meansthat you usually cannot hear stations at your listening location thatextend beyond the horizon.During the summer, you might hear stations in the 30-50 MHz range locatedseveral hundred or even thousands of miles away. This phenomenon is knownas skip, and is caused by summer atmospheric conditions. This type ofreception is unpredictable but often very interesting.One useful service is the National Oceanic Atmospheric Administration(NOAA) Weather Radio's continuous weather broadcasts. These broadcastsadvise you of the current weather conditions, weather predictions, andalso contain information about any threatening weather. These stationsuse three frequencies - 162.40, 162.475, and 162.55 MHz. In most areas ofthe country, you can receive one or more of these frequencies.===Guide to the Action Bands===With the right frequencies programmed into the scanner, you can monitorexciting events. With a little investigation, you can find activefrequencies in your community. We can give you some general pointers, andyou can take it from there. Please use caution and common sense whenyou hear an emergency call. Never go to the scene of an emergency - itcould be the most dangerous thing you could ever do.Find out if there is a local club that monitors these frequencies.Perhaps a local electronics repair shop that works on similar equipmentcan give you the frequencies used by local radio services. A volunteerpolice or fire employee can also be a good source of this information.As a general rule on VHF, most activity is between 153.73 and 159.46 MHz.Here you find local government, police, fire, and most such emergencyservices. If you are near a railroad yard or major railroad tracks, lookbetween 160.0 and 161.9 MHz for signals.In some larger cities, there has been a move to the UHF bands for theseemergency services. Here, most of the activity is between 453.025 and453.95 MHz and again between 456.025 and 459.95 MHz.In the UHF band, the range between 456.025 and 459.95 MHz and againbetween 465.025 and 469.975 MHz is used by mobile units and controlstations associated with base and repeater units that operate 5 MHz lower(that is, between 451.025 and 454.95 and between 460.025 and 464.975 MHz).This means that if you find an active channel inside one of thesespreads, you can look 5 MHz lower (or higher, as the case may be) to findthe major base station/repeater for that radio service.== Preparation ==POWER SOURCESYou can power the scanner from any of the following three sources:*Internal batteries*A standard AC outlet (using an optional AC adapter)*The vehicle's battery (using an optional DC adapter)Using BatteriesYou can operate the scanner from five AA batteries. For longestoperation and best performance, we recommend alkaline batteries (RadioShack Cat. No. 23-552). Or, you can use rechargeable nickel-cadmiumbatteries (Cat. No. 23-125).Warning: The scanner has a built-in circuit that lets you recharge nickel-cadmium batteries inside the scanner. However, youmust never use this circuit when you have installed non-rechargeable batteries in the scanner. Be sure to set theswitch in the battery compartment to the correct position forthe type of batteries you install.1. Remove the battery compartment cover by pressing down on the arrow and sliding the cover in the direction of the arrow.2. Remove the battery holder from the compartment and remove any old batteries. Then, install five AA batteries, observing the polarity (+ and -) marked on the battery holder.3. Set the switch in the battery compartment to the correct position for the type of batteries you install. Set the switch to REG ALK BATT if you install regular or alkaline type batteries. Set the switch to NI-CAD BATT if you install nickel-cadmium type batteries.:Caution: Never set this switch to NICAD BATT when you install non-rechargeable batteries. If you attempt to recharge non-rechargeable batteries, they become very hot and might damage the scanner or even explode.4. Place the battery holder in the compartment so that the holder's metal contacts line up with the metal contacts in the battery compartment.5. Replace the battery compartment cover. The scanner beeps every 15 to 30 seconds when the batteries are low. When this happens, immediately replace or recharge all five batteries.Using an AC Power SourceTo power the scanner from AC power, you need Radio Shack's AC adapter (Cat. No. 273-1652). Use of another adapter could damage the scanner or the adapter.1. Be sure that you have set the switch in the battery compartment to the correct position. (See "Installing or Replacing Batteries.")2. Connect the adapter's green barrel plug to the adapter's cord and set the barrel plug's tip polarity to positive.3. Insert the adapter's plug into the scanner's EXT PWR jack.4. Insert the adapter power module into a standard AC outlet. This provides power to operate the scanner. Also, if you have installed rechargeable batteries and set the switch in the battery compartment to NI-CAD BATT, the adapter charges the batteries in the scanner.5. When you finish using the AC adapter, disconnect it from the AC outlet. Then, disconnect it from the EXT PWR jack.Using A DC AdapterYou can power the scanner from the vehicle's cigarette lighter socket,provided the vehicle has a 12-volt negative-ground electrical system. Todo so, you need Radio Shack's Power Cord Set (Cat. No. 270-1533).Note: In some areas, mobile use of a scanner is unlawful or requires a permit. Check the laws in your area.1. Ensure that you have set the switch in the battery compartment to the correct position. (See "Installing or Replacing Batteries.")2. Plug the adapter's plug into the scanner's EXT PWR jack.3. Insert the other end of the adapter into the vehicle's cigarette lighter socket. This provides power to the scanner. Also, if you have installed rechargeable batteries and set the switch in the battery compartment to NI-CAD BATT, the adapter charges the batteries in the scanner.4. When you finish using the DC adapter, disconnect it from the cigarette lighter socket. Then, disconnect it from the scanner.Note: Do not let the adapter's plug touch any part of the vehicle while the adapter is plugged into the cigarette lighter socket. Doing so could blow a fuse or damage the adapter.CHARGING NICKEL-CADMIUM BATTERIESThe scanner has a built-in circuit that recharges nickel cadmium batteries. To charge the batteries, set the switch in the batterycompartment to NI-CAD BATT, install the batteries in the scanner, and connect an external power adapter to the scanner, as explained in "Power Sources."Caution: Do not connect either adapter to the EXT PWR jack if you have not installed rechargeable batteries, and are unsure of theposition of the switch in the battery compartment, or know that the switch is set to NI-CAD BATT. Non-rechargeable batteries can become hot and even explode if you try to recharge them.It takes 10 to 18 hours to recharge batteries that are fullydischarged. You can operate the scanner while rechargingnickel-cadmium batteries, but the charging time is longer.Charging Hints: Nickel-cadmium batteries deliver more power if you occasionally let them discharge completely. To do this,use the scanner until reception becomes poor. Then, fully charge the batteries. If you do not do this occasionally, they can temporarily lose the ability to deliver full power.To prevent permanent nickel-cadmium battery power loss,never charge your batteries in an area where thetemperature is above about 80 degrees Fahrenheit. Also,if you use an external charger, do not overcharge thebatteries.If you plan to use rechargeable batteries, do not use anyadapter other than those specified in "Power Sources."While adapters of the same voltage rating and at leastthe minimum current rating could power the scanner,other adapters might not work properly with the chargingcircuit in the scanner, and could permanently damage thebatteries or the scanner.The first time you use a set of nickel-cadmium batteries,charge them at least 24 hours to bring them to a fullcharge.CONNECTING THE ANTENNAAttach the flexible antenna to the antenna jack on top of the scanner.Slip the slot in the antenna's connector over the protrusion on the jack.Then, press down and rotate the base of the antenna until it locks intoplace.The scanner's antenna jack makes it easy to use the scanner with a varietyof antennas. You can remove the supplied antenna and attach a differentone, such as an external mobile antenna, telescopic antenna, or outdoorbase antenna. Radio Shack stores sell the antenna connector adapters thatlet you use these antennas.Use coaxial cable to connect an outdoor antenna. Always use 50-ohmcoaxial cable. For lengths over 50 feet, use RG8 low-loss dielectriccoaxial cable.Warning: When installing or removing an outdoor antenna, use extremecaution. If the antenna starts to fall, let it go! It couldcontact overhead power lines. If the antenna touches the powerline, contact with the antenna, mast, cable, or guy wires cancause electrocution and death! Call the power company to removethe antenna. Do not attempt to do so yourself.ATTACHING THE BELT CLIPYou can connect the supplied belt clip to the scanner to make it easier touse the scanner when you are on the go. Connect the clip to the scannerwith the two provided screws.CONNECTING AN EARPHONEFollow these steps to use the earphone for private listening:1. Turn the volume control to its minimum position.2. Plug an earphone into the EAR jack on top of the scanner. This automatically disconnects the speaker. We recommend Radio Shack'searphone Cat. No. 33-175. In a noisy environment, mono headphones (Cat. No. 20-210) make listening easier.3. Adjust the volume to a comfortable level.Warning: Do not listen at extremely high volume levels, especially when using an earphone. Extended high-volume listening can lead to permanent hearing loss.CONNECTING AN EXTENSION SPEAKERIn a noisy area, an extension speaker positioned in the right place, mightprovide more comfortable listening. Plug the speaker cable's 1/8-inchmini-plug into the scanner's EAR jack.== Specifications == <nowiki>Frequency Coverage:</nowiki> <nowiki></nowiki> <nowiki>VHF-Lo..........................................29-50 MHz (in 5 kHz steps)</nowiki> <nowiki>Ham.............................................50-54 MHz (in 5 kHz steps)</nowiki> <nowiki>Government....................................137-144 MHz (in 5 kHz steps)</nowiki> <nowiki>Ham...........................................144-148 MHz (in 5 kHz steps)</nowiki> <nowiki>VHF-Hi........................................148-174 MHz (in 5 kHz steps)</nowiki> <nowiki>Ham/Gov't..................................406-450 MHz (in 12.5 kHz steps)</nowiki> <nowiki>UHF-Lo................................... .450-470 MHz (in 12.5 kHz steps)</nowiki> <nowiki>UHF-Hi ("T")...............................470-512 MHz (in 12.5 kHz steps)</nowiki> <nowiki>Channels of Operation.
