Because of the nature of this product, my usual evaluation format will not be used. This will just be a brief informational page with three photographs and a video on it.

The PRO-51 Mobile Direct-Entry Scanner/Weather Radio (originally sold by Radio Shack) is a handheld 200-channel direct-entry radio scanner. That is, you can take it virtually anywhere (not underwater of course!) and listen to police, paramedics, the fire department, etc. plus the NOAA weather radio stations to that you can keep on top of the weather in your area at the drop of a hat. Any hat.


* Product is no longer being sold as new from Radio Shack; however they are readily available on the used market.

Here are some of the features and the operating instructions, lifted directly off the scanner's support website -- no changes to spelling, capitalisation, grammar, formatting, or syntax were made.

        Band Search - lets your scanner search the frequencies allocated to
                      the air traffic, fire, marine or weather services, so
                      you can listen to the services you prefer, even if you
                      do not know the frequencies.

   2-Second Scan Delay - delays the scanning mode for 2 seconds before moving
                      to another channel, so you can hear more replies.

      Memory Backup - keeps the channel frequencies stored in memory for up
                      to 3 days during power loss.

  Lock-Out Function - keeps channels you select from being scanned.

   Priority Channel - checks your most important channel every 2 seconds so
                      you don't miss important calls on the channel you
                      specify.

   Ten Channel-Storage - lets you store 20 channels in each of 10 banks to group
              Banks   frequencies so you can easily identify calls.

   Monitor Memories - lets you store up to 10 channels you locate during a
                      frequency search which you can then transfer to per-
                      manent memory.

   Frequency Search - scans through every available frequency at up to 100
                      steps per second to find interesting broadcasts.

This scanner can receive all of these bands:

29 - 29.7 MHz (ham radio 10m)
29.7 -50 MHz (VHF Lo)
50 - 54 MHz (ham radio 6m)
108 -136.975 MHz (aircraft)
137 - 144 MHz (government)
144 - 148 MHz (ham radio 2m)
148 - 174 MHz (VHF Hi)
406 - 450 MHz (ham radio and government)
450 - 470 MHz (UHF standard)
470 - 512 MHz (UHF "T" band)
806 - 823.9375 MHz (public service)
851 - 868.9375 MHz (UHF Hi)
896 - 1125.956 MHz (UHF Hi)



Setting Volume and Squelch Follow these steps to set VOLUME and SQUELCH. 1. Rotate VOLUME 1/4 turn clockwise and SQUELCH fully clockwise. 2. Slowly turn SQUELCH counterclockwise until you hear a hissing sound. 3. Slowly turn SQUELCH clockwise until the hissing stops. NOTE: If you want to listen to a weak or distant station, turn SQUELCH counterclockwise. You might hear hissing between transmissions. Using The KEYLOCK Once you program your scanner, you can protect it from accidental program changes by turning on the key lock feature. In this mode, the only controls that operate are SCAN, MANUAL, LIGHT, K/L, VOLUME and SQUELCH. To turn on the KEYLOCK feature, press K/L until KEYLOCK appears on the display. To turn it off, press K/L until KEYLOCK disappears. Storing Frequencies You can store up to 200 frequencies into your scanner's channels. Follow these steps to store frequencies. 1. Press MANUAL. Enter the channel number you want to program. 2. Press PROG. PGM appears on the display to indicate the scanner is in the programming mode. 3. Enter a frequency. 4. Press ENTER to store the frequency. If you made a mistake in Step 3, Error appears on the display and the scanner sounds three beeps. To clear the display, press CLEAR. Then proceed again from Step 3. NOTE: If you want to program the next channel in sequence, repeat Steps 2 - 4. 5. Repeat Steps 1 - 4 to program more channels. Searching For and Temporarily Storing Active Frequencies Good references for active frequencies are Radio Shack's "Police Call Guide including Fire and Emergency Services," "Official Aeronautical Frequency Directory" and "Maritime Frequency Directory". We update these directories every year, so be sure to get a current copy. If you do not have a reference to frequencies in your area, use a limit or direct search to find a transmission. Also see "A Guide to the Action Bands". NOTE: Press DELAY if you want to make the scanner pause 2 seconds after a transmission ends before it proceeds to the next frequency. Limit Search Limit search lets you search within a specific range of frequencies. -L- appears on the display during a limit search. 1. Press PROG, then LIMIT. Lo appears on the display. 2. Enter the lower limit of the frequency range you want to search. 3. Press ENTER, then LIMIT. Hi appears on the display. 4. Enter the upper limit of the frequency range. 5. Press ENTER. 6. Press \/ to search from the upper to the lower limit or press /\ to search from the lower to the upper limit. 7. When the scanner stops on a transmission, press MONI to store the freq- uency into the current monitor memory, or press /\ or \/ to continue the search. Direct Search Direct Search lets you search up or down from the currently displayed frequency. -d- appears on the display during a direct search. 1. Press MANUAL, the channel number and MANUAL in sequence to select a frequency stored in a channel. 2. Press /\ or \/ to search up or down from the selected frequency. 3. When the scanner stops on a transmission, press MONI to store that frequency in the current monitor memory. Or, press /\ or \/ to con- tinue the search. Using the Band Search Keys You can search for air, fire, marine, or weather transmissions even if you do not know the frequencies being used in your area. The scanner is pro- grammed with all frequency ranges allocated to these services. To use this feature, press BAND. Then press the desired service band key (AIR, FIRE, MARINE or WX). The scanner starts searching the band. When the scanner stops on a transmission, you can store that frequency into the monitor memory by pressing MONI. To continue scanning, press /\ or \/. NOTES: To make the scanner pause 2 seconds after a transmission before proceeding to the next frequency, press ./DELAY until DLY appears. See "Delay." The delay feature is programmed band by band in this mode. The 800 and 900 MHz bands are allocated to Trunked services. This means that the police and fire departments share the frequencies with other services. The scanner might stop on transmissions by other services in these bands. Because there are many different frequency ranges allocated to fire and police departments, it takes several minutes to search all frequencies when you scan for these services. Listening To Monitor Memories You can listen to a monitor memory by pressing MANUAL, MONI, and then the number of the monitor memory you want to listen to. NOTE: Turning off the scanner clears the frequencies stored in the monitor memories. Moving a Frequency From A Monitor Memory To A Channel To begin scanning the channels, press SCAN. The scanner scans through all non-locked channels in the activated banks. Set SQUELCH so you do not hear the hissing sound between transmissions. (See "Locking Out Channels" and "Turning Channel-Storage Banks On and Off.)"




To change the batteries in your scanner when they poop out, turn the unit over (so that all of the little buttons face the floor). At the bottom, you'll see a ridged area. Press in on it, and use the same ribbed area to push the battery door up. Buy an airplane ticket to Juneau AK. USA, rent a car at the airport, drive south on Egan Drive untl you reach downtown Juneau. Stop at Marine Park, walk the very short distance to the Steamship Dock, and huck it at a bouy in Gastineau Channel where it might hit a flounder on the way down to the sea bottom...O WAIT!!! YOU'LL REALLY NEED THAT!!! So just set it aside instead.

In the battery door itself (which is the last place you'd typically look), remove and dispose of or recycle the two used AA cells as you see fit. In the scanner's battery compartment, you'll see two more AA cells; do the same with those.

Install two new AA cells in the battery door, orienting each cell so that its flat-end (-) negative faces the spring for it in each chamber. Do the same with the battery compartment in the scanner itself.

Place the battery door on so that its upper edge is fitted first, and then swing it down until it latches shut.

Aren't you glad that you didn't fly to Juneau and chuck that battery door into Gastineau Channel now?

TEST NOTES:
Product was given to me by my aunt in mid-2012.
Since it was a gift from a loved one, the "" icon will appear appended to its listings on this website to denmote the fact that no abusing testing will be performed on it. However, since it is a radio, no punishments would have been meted out anyway -- as somebody commented about another radio's eval. on this website in mid-2005, "
Radios are made to be loved... not punished!" so this scanner would be in loving hands regardless of its origin.
