Question about Radio Shack Pro-94 Scanner

162.550 NOAA weather frequency

Hi There, For some reason my Pro-94 1000 Channel Scanner has a problem receiving the above mentioned frequency. It will lock on the frequency, talk about 3-4 seconds and then just quit talking.

I have had the Pro-94 for several years and never had a problem before this started about 2 weeks ago.

Any ideals would be greatly appreciated.

The other frequencys work ok, its just the weather ones that I am having trouble with. I have tried new batteries, and I have the adapter to use with electric, but neither helped the problem.

You may also have pressed the ALT button, which will put the scanner in ALERT mode, esentially turning it into a weather alert radio. The weather frequencies will remain silent until the NOAA station you are listening to issues some kind of watch/warning or weekly test.

Re: 162.550 NOAA weather frequency

I had this problem also. It appears that in my case the problem was that I had accidentally pressed the trunk button while accessing the weather frequencies using the SVC function (E button). Pressing it again while scanning weather frequencies when using the SVC function will clear the problem - if that is the cause.

Re: 162.550 NOAA weather frequency

If your still having the problem, it could be that the transmitter for that freq lost some of it's power, so your scanner cannot pick up a clear signal. If everything else is working ok, that's my guess. Hope this helps,,, Mechanic

Can't seem to get any activity even after programming some frequencies in to it(BC72XLT)

Are you sure that the frequencies you programmed are active in your area? Try a weather band search (press Func and Svc) to verify that the scanner is working properly. If you receive one or more NOAA weather broadcast channels then you need to visit and check their database for active freqs in your area. If you cannot receive weather then you have an antenna or receiver problem.

My pro 2018 scanner wont pick anything up where i live could there be something wrong with the scanner or do i need a better antenna i live in holmes county ohio

First try picking up the NOAA Weather broadcasts. They're transmitted on seven frequencies (162.400, 162.425, 162.450, 162.475, 162.500, 162.525, 162.550) and at least one should be active in your area. To check reception, just press the WX key on your scanner. If you can pick up one or more of the frequencies, you'll know that the scanner is functioning properly. If not, your scanner is likely in need of repairs - a questionable move due to its age.

If the scanner is functioning (receiving the weather band), try a quick RESET. use a paperclip or pen point to press the recessed RESET button on the back of the scanner.

Make sure that you have programmed local active frequencies into the scanner. For a comprehensive database, and a lot of other useful scanning information, visit:

After all of the above, if you are receiving weather but no local transmissions, I recommend that you try an external antenna.

If you need the manual for your scanner, you can download and print it, at no cost, here:

The NOAA weather frequencies have constant broadcasts, so your scanner "locks" onto them. The only ways to prevent this are to either delete the weather frequency or lock it out. To delete, just program the frequency "0.0" (zero point zero) into the channel. To lock it out, press the L/O key while on the weather freq.

Scanner not picking up local police-Fire freq

Do you still receive NOAA weather frequencies? Sounds like your local agencies have switched from simplex/standard frequency operation to trunking. I suggest you visit to view the latest on active frequencies and systems in your area.

I have a bc350c 800 mhz and cant get nothing but static how to i get the police channels to work

Try tuning known frequencies, such as the NOAA weather channels, to verify the working condition of your scanner. If it picks them up, you don't have your local police system/frequencies programmed properly. If there's no reception, even on NOAA, you have an antenna or receiver problem that may need professional attention.

In case you need it, you can download/print the manual for your scanner here:

I need to reprogram my Realistic Pro-2023 police scanner. I do not have my local police codes nor do I know how to reprogram it. Help.


For a a comprehensive database of active frequencies in your area, visit:

1. Turn on your scanner by turning VOLUME clockwise.

2. Press [MANUAL], enter the channel number you want to program, then
press [MANUAL] and [PROGRAM]. The channel number flashes to indicate
you are programming the channel.

3. Enter a frequency.

4. Press [ENTER] to store the frequency. If you make a mistake in Step
3, ERROR appears on the display. Proceed again from Step 3.

5. If you want your scanner to pause after each transmission before
scanning to the next channel, press [DELAY] so that DELAY appears in
the display. See "Using the Delay Feature."

6. To program more channels, repeat Steps 2-4. If you want to program
the next channel in sequence, simply press [PROGRAM] and repeat Steps
3 - 4.


Use the SQUELCH control to decrease your scanner's sensitivity to weak
signals. This allows the scanner to receive only the strongest

1. Turn the SQUELCH and VOLUME controls fully counterclockwise.

2. Turn the VOLUME control clockwise until you hear a hissing sound.

3. Slowly turn the SQUELCH control clockwise until the hissing sound


To begin scanning the channels, press [SCAN]. Your scanner scans through
all the channels except the ones you have locked out. Be sure to read the
following sections to get the full benefit from your scanner's special


Many agencies use a two-way radio system that might have a 2 second silence
(or more) between a query and a reply. To keep from missing a reply,
program a delay on the channels you identify as operating this way.

To program a delay, select the channel and press [DELAY] so that DELAY
appears on the display. Now when your scanner pauses at an active channel
when scanning, it waits for 2 seconds after the completion of each
transmission on that channel before it resumes scanning.

If you do not want your scanner to pause, select the channel and be sure
that DELAY is not on the display. If DELAY appears on the display, press
[DELAY] to turn it off for that channel.


You can make your scanner scan more efficiently by locking out channels
that you have not programmed. Manually select the channel and press [LOCK
OUT] so that LOCK OUT apperas on the display. This is also handy for
locking out channels that have a continuous transmission. You can still
manually select locked-out channels for listening.

To unlock a channel you have locked, manually select the channel and press
[LOCK OUT] so that LOCK OUT disappears from the display.

NOTE: You cannot lock out Channel 1.


Channel 1 is designated as your scanner's priority channel. You can turn
on the priority feature so that you do not miss transmissions on Channel 1,
even if you are monitoring another channel.

Press [PRIORITY] so that PRIORITY appears on the display. Now your scanner
checks Channel 1 every 2 seconds, and stays on the channel if there is any


You can continuously monitor a specific channel without scanning. This is
useful if you hear an emergency broadcast on a channel and do not want to
miss any details-even though there might be periods of silence-or if you
want to monitor a specific channel.

Follow these steps to manually select a channel.

1. Press MANUAL.

2. Enter the channel number.

3. Press MANUAL again.

Or, if your scanner is scanning and stops at the desired channel, press
MANUAL one time. (Pressing MANUAL additional times causes your scanner
to step through the channels.)


The FCC (Federal Communications Commission) has allocated several channels
for use by the National Oceanic and Atmospheric Administration (NOAA). We
have preprogrammed your scanner with all of the frequencies available to
NOAA. To hear your local forecast and regional weather information, simply
press [WX]. Your scanner begins scanning through the weather band, and WX
SEARCH appears on the display.

Your scanner should stop within a few seconds, and you hear the local
weather broadcast. If the broadcast is weak, you can press [WX] again
to scan through the rest of the weather band.

Scanner scans but will not pick up traffic

You didn't mention the scanner model, your location, or any specifics that could could help focus in on the problem, but here are some general guidelines for scanning:

1. Make sure that the scanner powers on from either AC power or batteries and that you have a proper antenna connected..
2. Check basic operation by turning the volume about halfway up and then rotating the SQUELCH control in both directions. You should hear a loud hissing noise. If you cannot hear anything while doing this the scanner is in need of professional repair.
3. Check scanner reception by programming a NOAA Weather frequency. 162.550MHz is the primary in most areas, but 162.400, 162.475, 162.425, 162.450, and 162.500 are other possibles). If you receive weather broadcasts on one of these frequencies, the scanner is working. If not, it probably needs professional repair.
4. If it passes the above tests, you need to make sure that you've programmed the right frequencies into the scanner. These will vary by location, and for a comprehensive database of active frequencies in your area, visit:

I hope that this information helps. If not, please get back to us with specifics and we will do our best to get the scanner working for you.

162.550 NOAA weather frequency

Hi and welcome to FixYa,

I am not aware of any computer receiver ported for USB connection capable of 162.550 MHz; almost all are regular FM band. There are however amateur/ham radio equipment that could be interfaced with the PC that covers 136 to 174 Mhz.

If your requirement is to be able to monitor NOAA weather broadcasts, it might be simpler to use Internet Radio/audio streaming. NOAA addresses this particular issue here and here among others.

Good luck and thank you for using FixYa.
