SOURCE: Radio scanner not receiving

The Realistic Pro-2025 relies on a quartz lock-loop signal synthesizer to receive signals, the synthesizer might of gone bad, chalk it up to old age. The Realistic PRO (Progressive Receiving Occilator) models are not around anymore, they went obsolete years ago. It's nice that you have one, they are worth some money on eBay. However I'm afraid it will cost you more money to fix the synthesizer than the radio is actually worth. It would be best to use your Radio Shack PRO-49. Realistic is a division of Radio Shack founded by Tandy Corp, basically you've been using a Radio Shack scanner the whole time. So if you have any complaints, take it up with them, you won't find Realistic anymore.

Hope this helps!

SOURCE: NO SQUELCH

I have a Radio Shack Pro 97 Scanner that I received as a present 1-1/2 years ago. It was working just fine and then suddenly there was no squelch or volume. The keys make noise when pushed, but there is no sound for the squelch or volume. The scanner scans the frequencies but does not stop and play. I went on line and found that other people were having the same problems. I went back to the store that the unit was purchased from and received no help what so ever, they said it’ s off warranty and I was out of luck, nice way to do business??. I think that something that cost as much as this should not be junk after a short period of time. I hope you can help me with this problem I do like radio shack, but I can’t afford to buy items that don’t stand up.

Sincerely

SOURCE: realistic pro 2020 scanner

The Realistic PRO-2052 is an old (vintage) scanner receiver with fixed AM and FM modes on the bands it cover, as specified by the U.S. band allocation. The PRO-2020 covers only the VHF and UHF frequencies and modes AM and FM is not user selectable. Frequencies can be programmed into any of the 20 memory channels

U.S. Coverage: (varies from state to state and other countries. We don't use 30-50 Mhz here in the Philippines for 2 way mobile communications, except for cordless phones)

30-50 Mhz Lower VHF at FM narrowband only (covers mobile, emergencies, businesses, etc. and
cordless phones)
108-136 Mhz Aircraft band at AM narrowband only
138-174 Mhz Amateur and Commercial band at FM narrowband only (2 meter band)
410-512 MHz Amateur and Commercial band at FM narrowband only (70 cm band)

If you're trying to select AM or FM for a specified frequency, I'm afraid you can't do that as it is not selectable.

If you are trying to program AM Broadcast frequencies (mediumwave (MW) or FM Broadcast frequencies (FM radio stations), those were not covered by your PRO-2020's microprocessor. Even if you modify your scanner to receive those bands, you will not hear radio transmission properly since the receiver do not decode FM wideband, which is the standard mode for FM broadcast and Television band.

SOURCE: Radio Shack PRO-91 scanner keypad doesn't work

Try a master reset. You will lose all of your current programming but it resets the unit back to its original state when you purchased it. here are the directions from page 53 in your manual.


Resetting the Scanner
If the scanner's display locks up or stops operating
properly, you might need to reset the scanner.
Caution: This procedure clears all the information
you have stored in the scanner. Before you reset the
scanner, try turning it off and on to see if it begins
working properly. Reset the scanner only when you
are sure it is not working properly.
1. Turn off the scanner.
2. While holding down 2, 9, and Hold, turn on the
scanner. It takes about 3 seconds to initialize
and CLEAr appears.

Buzzing noise in realistic pro 62 airband scanner


Check your squelch settings.
The frequency you are trying to listen might be a "birdie", a frequency that interacts with the electronic noise in the unit. This is especially the case if the issue is only on one frequency.

Is the Realistic Pro 20-20 Scanner obsolete? I can only program three digits on each side of the decimal.... Most channels today are in the xxx.xxxxx format.


Your PRO-2020, circa 1982, is old and tired, but not quite obsolete. The receiving bandwidth of this oldie is wide enough that you can just ignore the fourth digit. In some cases this may result in interference from an adjacent frequency, but it will usually work just fine. The 2020 is further limited in that it will not receive 800MHz frequencies, and it is not capable of tracking trunking systems or receiving digital transmissions, but what it does, it still does well. The PRO-2020, by the way, was one of the first keyboard-programmable scanners, and the first used in military intelligence surveillance operations.

Wanted manual realistic 2010scanner


The realistic 2000 series scanners do not have a "VFO" (variable frequency occilator) in the true meaning of the sence. This basicly means that they can only scan the channels or memories that you have programmed.

You can however set a low frequency (like 144 Mhz) and a high frequency (like 145 Mhz) and the scanner will "bounce" between the two, picking up anything in between.

Do you have the operating manual? If not, here is a copy

Turn on your Pro-2010 by rotating [VOLUME] clockwise. (When first turned on, your Pro-2010 may start scanning).
Rotate [SQUELCH] fully counterclockwise. You'll hear a rushing noise from the speaker. Slowly rotate [SQUELCH] clockwise until the noise just stops.
You're now ready to start entering frequencies.

Programming Frequencies
Before programming frequencies, make sure your Pro-2010 is turned on and the SQUELCH is adjusted.
Suppose you want to program Channel 1 to receive 162.55 MHz. Here's how you would do it:

1. Press [MANUAL] and select channel 1. You can do this in two ways:
press [MANUAL] continuously until the Display indicates Channel 1 or
by pressing [1] [MANUAL].

2. Press [PROGRAM] to enter the programming mode.

3. Enter the desired frequency. In this case, press the [1] [6] [2] [.]
[5] [5] keys. Check the display to make sure the frequency it shows
is the one you meant to program. If it is, press the [ENTER] key.

4. To add more frequencies, just press [PROGRAM] to advance to the next
channel and follow the steps above.

5. If you ever want to change the frequency entered for a specific
channel, just enter the new frequency "over" the old frequency using
steps 1, 2, and 3.

Make a mistake while entering the frequency? Just press [CLEAR], enter the correct frequency and press [ENTER]. If you're entering a new frequency in place of an old one, the old frequency won't be "erased" when you press [CLEAR]. It will remain stored on that channel until you correctly enter a
new frequency and press [ENTER].

You'll hear a "peep" sound as you press the various keys. This lets you know the key has been properly "entered" into your Pro-2010.

Using the Scanning Function
Your Pro-2010 will automatically scan all the channels you've programmed and stop whenever it finds a signal. To scan channels, just press the [SCAN] key.
To stop scanning, just press [MANUAL] and you can select specific channels
you want to listen to.

IMPORTANT! Your Pro-2010 won't scan unless SQUELCH is set to the point where no sound is heard if a signal isn't being received.

Delay Function
When your Pro-2010 is scanning, it will stop whenever it finds a signal on a channel. As soon as the signal ends, the scanning function will resume. Most communications heard will be two-way. To make sure you don't miss any replies, press [DELAY]. This will cause your Pro-2010 to stay on a channel for two seconds after the end of a transmission, giving you time to hear any reply. To release the Delay function, just press [DELAY] again. The Delay indicator will show on the display when the Delay function is used.

Lockout Function
You may want your Pro-2010 to "skip over" certain frequencies while it's scanning (such as continuously transmitted weather broadcasts). To "lock out" such channels, follow these steps:
1. Press [MANUAL] to stop scanning. Continue to press [MANUAL] to
advance to the channel you want to lock out.

2. When you reach the channel, press [LOCK OUT]. The display will show
[o] to indicate this channel will be skipped over during scanning.

3. To release the lockout, press [MANUAL] to stop scanning. Advance to
the channel that is locked out and press [LOCK OUT] once again. [o]
will disappear from the display.

If you use the lockout function on all channels, scanning will be impossible - you'll only be able to change channels using [MANUAL].

Speed Selection
Your Pro-2010 will normally scan channels at a rate of four channels per second. If you press [SPEED], channels will be scanned at a rate of nine per second. Press [SPEED] again to return to a rate of four channels per second.

Priority Function
You might want to scan other channels yet not miss a call on a channel of particular interest to you (police, fire, ambulance, etc.). The Priority function will let you scan other channels - but if a call is received on the Priority channel, your Pro-2010 will automatically switch to the
Priority channel!

1. Only Channel 1 can be used as Priority Channel: Key in the desired
Priority frequency into Channel 1.

2. Priority function works only when the unit is in Scan or Manual mode.

3. Press [PRIORITY] to start Priority function. A [P] will appear on the
display.

4. Press [MANUAL] or [SCAN] to listen to other channels. Your Pro-2020
will check the Priority channel and switch to it if a signal is
received on it.

5. To cancel Priority function, press [PRIORITY] again. the [P] will
disappear from the display.

SEARCHING WITH YOUR PRO-2010
One great feature of your Pro-2010 is its ability to "search" for frequencies being used. This means you can hear all the action on the airwaves in your area! To use this great feature, just follow these steps:
1. Press [PROGRAM] key.

2. Press [LIMIT] key. Enter the lower limit of frequency range to be
searched (such as 45.00 MHz). Press [ENTER].

3. Press [LIMIT] key again. Enter the upper limit of frequency range to
be searched (such as 46.00 MHz). Press [ENTER].

4. Press either [up arrow] or [down arrow] to start Search. [Down arrow]
will start search from the highest frequency and go down. [Up arrow]
will start from the lowest frequency and go up.

5. You can control the speed of the search by using the [SPEED] key to
accelerate or to slow down the search.

6. Search will stop when a frequency is found with a signal. To restart search, press [up arrow] or [down arrow]. In Program Mode, search range will be displayed each time [LIMIT] is pressed. It is impossible to change the lower frequency only: to change lower frequency you must change higher frequency first. The higher frequency can be changed any time.

Storing Frequencies
If you want to enter some of the frequencies found during search, do this:
1. Press [MONITOR] when your Pro-2010 finds a frequency you want to store.

2. Use [MANUAL] key to select a channel to enter the frequency your Pro-
2010 found. The display will show the frequency currently stored on
the channel, but don't worry - the old frequency will be erased when
you start to enter the new one.

3. Press [PROGRAM].

4. Press [MONITOR] again. The new frequency found during the search will
be displayed.

5. Press [ENTER] to put the new frequency into the channel in place of
the old frequency.

6. Press either [up arrow] or [down arrow] to resume the search. To
return to manual or program operation, press [MANUAL] or [PROGRAM].
To resume the search from one of the limit frequencies, press [LIMIT]
and then [up arrow] or [down arrow].

Error Indications
Sometimes when you try to enter a frequency for a channel or as a search range limit, you may find an ------ on the display. This means the frequency is in error and you won't be able to enter it into your Pro-2010. Such frequency errors usually mean you've entered a frequency outside the ranges your Pro-2010 operates on (such as 225.00 MHz) or you've put the decimal point in the wrong place (14.682 MHz instead of 146.82 MHz). Check carefully to find your mistake and then press [CLEAR]. You can now enter the correct frequency.

Hope this helps,
