Question about Uniden BC340CRS Base Scanner

1 Answer

A blank spot in reception on my 340 while a signal is heard

While in scan mode, and it stops on a signal, like the local sheriff or anything at all, there is a consistent, regular pause in the signal. No problem on AM or FM radio. I have moved the scanner away from any source of device that emits RF, and still the same. I guess you could describe it like a regular pulse, except that it is a blank spot in reception.Thank you

First thing I would check is to see if you have the "Priority" Function set on. If it is on a PRI would be illuminated in the display. When this is on the scanner will pause and check you "priority" Channel every 2 seconds, even when it is stopped on a transmission. Turn off the Priority by pressing the PRI button while it is scanning. Se if theis helps,

Homepatrol scans but does not stop at any signels


Squelch setting set too high perhaps, reduce the squelch until you can hear something, then turn it up slowly until it start to scan again.
Radio Control Bar
The row of buttons across the top of the Main screen lets you fine-tune HomePatrol-1 reception, access Help, and reenter system configuration.
Button
Definition
Squelch
Sets how strong a signal must be before HomePatrol-1 stops on it.
Range
Controls how many channels are selected based on your location and systems' locations. Small range settings result in fewer systems and departments selected. A selection bar lets you set the range in 2-mile increments. Each screen tap is 0.5 miles.
Atten (Attenuation)
Reduces signal interference if you are in an area where there are a lot of radio signals. If Attenuation is set to ON, the status indicator turns red.
GPS
Displays the status of a connected GPS unit.
Help
Displays Help text.
Tap and hold to redo initial setup configuration.

Hope this helps

My scanner not pickin up


Hi Terry,

You forgot to post the Make & Model of your radio scanner, as they're not all the same.

I'll use generic terms for your (unknown) radio scanner.

Have you programmed any frequencies into your scanner? If not, there's the reason for no reception.

You are required to program frequencies into your radio scanner, before it will receive anything.

If you have programmed your favourite frequencies, did you check to see if they are applicable to your area/location?, If so, then after programming, did you press the L/O key? If so you have locked out your frequency(s) from scan mode. To undo this you will need to press the Mon/Hold key during scan made, this will stop the scanner from scanning, and you can now go through each programmed channel and press L/O key so that L/O icion on the display is out, once you've completed this task, you should be able to scan and when a transmission is received, the unit will stop scanning during the transmission.

I hope that I have assisted you.

Regards,
Peter

How can i stop the squelch ive tryed turning the sqcuelch doesnt help


Plug the AC adapter into the back of the scanner and into a wall electrical outlet. Screw the antenna into the receptacle on the back of the scanner (extend the antenna to full length for best reception).

  • 2 Set the squelch level to allow signals to be heard by turning the squelch knob counterclockwise. Rotate the volume knob clockwise until you hear static. Slowly turn the squelch knob clockwise until the static noise disappears.
  • 3 Start programming frequencies into the scanner by pressing the "Manual" button.
  • 4 Press the up arrow or down arrow key until the channel you wish to program is visible on the display.
  • 5 Use the numbers on the keypad to enter the frequency for the local transmitter you wish to receive.
  • 6 Press the "E" key to complete the process of entering the frequency.
  • 7 Repeat steps 3 through 6 for each additional frequency you wish to monitor.
  • 8 Press the "Scan" key to start the scanning process. The scanner stops on a channel when it detects a signal strong enough to hear over the squelch setting. Two seconds after the signal stops, the scanning process resumes.

    My scanner no longer scans the local police and sheriff frequencies. It will only scan the next county sheriff frequencies. It was originally programmed to scan Omaha police and Douglas Co. sheriff.


    It's possible that your county services have switched to a trunking system, leaving you with nothing but "dead" frequencies. To check the frequencies and systems that are currently in use in your area, visit:

    I have a uniden bearcat scanner and cant pick up my local police dept. I put the frequency in and still dont hear anything. I have a bc145xl 16 channel scanning radio and want to know if its compatible...


    If you programmed the correct frequency, you should be getting reception. Check www.RadioReference.com to verify the frequency. Otherwise, you may be too far from the transmitter to receive signals. Try your scanner in other locations, check your antenna, and try receiving the PD on another scanner.

    The MARCS - Ohio Multi-Agency Radio Communications system - is a Motorola Type II SmartZone Omnilink Trunking system that utilizes APCO-25 digital transmissions. Your BC145XL is not compatible with trunking or digital systems. In order to follow the MARCS you will need one of the following scanners:
    GRE PSR-500, PSR-600
    Radio Shack PRO-106, PRO-197, PRO-96, PRO-2096
    Uniden BC250D, BC785D, BC296D, BC796D, BCD396T, BCD396T, BCD996T, BCD996XT, or the brand new HomePatrol-1

    New BC355C put 7 channels in,but only will stop on 2


    1. Be sure sure that your squelch is adjusted properly. While scanning, turn the SQUELCH control down slowly until scanning stops and you hear a hissing sound. Then slowly turn the control back up until scanning resumes. That will set a proper threshold level for the frequencies you're monitoring.
    2. Be sure that signals are not blocked in your area. Topography plays a large part in VHF and UHF radio reception. A hill, a tall building, even a thick grove of trees can prevent a signal from reaching your antenna.
    3. It's possible that there was just no traffic on the five freqs while you were listening.
    4. Be sure that the frequencies you've programmed are assigned in your area.
    5. For a comprehensive database of active frequencies in your area, visit:

    Won't pick anything up (uniden BC72XLT)


    Not sure this would be a solution but...
    Make sure you don't have the Ch. Locked out so it just skips them..

    You may also try and let the scanner sit on one frequency that you know has chatter and see if you receive.

    This unit also picks up local weather try that feature and you can tell if you reception is working or not.
