8. Repeating the Process:
Repeat steps 3-7 to program additional channels.
9. Exiting Programming Mode:
Press the “MENU” button repeatedly until you return to the scanning mode.
Common Mistakes and How to Avoid Them
- Incorrect Frequency Entry: Double-check the frequency before pressing “E/Yes.” Even a small error can prevent you from hearing anything.
- Wrong Modulation: Using the wrong modulation (AM/FM) can significantly reduce reception quality. Consult the frequency information.
- Forgetting to Enable the Channel: After programming, ensure the bank and channel are enabled for scanning.
- Not Using a Proper Antenna: The stock antenna is often inadequate. Consider upgrading to an external antenna for improved reception.
- Programming Too Many Frequencies: Overloading the scanner with too many frequencies can slow down scanning and make it difficult to find what you’re looking for.
Understanding Banks and Scanning
The Uniden BC125AT scanner has 10 banks, each capable of holding 50 channels. You can group channels by type (e.g., police, fire, aviation) and assign them to different banks. To scan a particular bank, ensure it is enabled.
To Enable/Disable a Bank:
- Press the “FUNC” button.
- Press the number key corresponding to the bank you want to enable or disable (1-0).
- The bank number will appear or disappear on the display, indicating whether it is enabled or disabled.
Programming Software and PC Connectivity
While manual programming is possible, using programming software simplifies the process, especially when dealing with a large number of frequencies. Several software options are available, often requiring a USB programming cable to connect the scanner to your computer. Popular options include:
- ARC125: Comprehensive software with advanced features.
- Butel ARC125: Another popular option offering similar functionality.
These programs allow you to import frequency data from databases, edit channels easily, and backup your scanner configuration.

Frequently Asked Questions
How do I unlock the keypad on my Uniden BC125AT?
The keypad can be locked and unlocked by pressing and holding the FUNCTION key, then pressing the L/O key (lockout). A key symbol will appear on the display when the keypad is locked.
What does “L/O” mean on my scanner?
“L/O” stands for Lockout. It allows you to temporarily skip channels or frequencies that you don’t want to hear during scanning. It’s a useful feature to reduce noise and focus on relevant transmissions.
How do I find the correct frequencies for my area?
The best resource is RadioReference.com. It’s a community-driven database that contains detailed information on radio frequencies for almost every location. You can also check the FCC license database or contact your local public safety agencies.
What is the purpose of CTCSS and DCS tones?
CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital Coded Squelch) tones are used to filter out unwanted transmissions and only hear signals that have the correct tone. They are commonly used on repeater systems.
My scanner isn’t picking up anything. What could be wrong?
There are several possibilities: You may have incorrect frequencies programmed, the channels might be locked out, the squelch may be set too high, or you may be in an area with poor signal coverage. Check these settings first.
Can I use my scanner to listen to cell phone calls?
No. Modern cell phone calls are digitally encrypted, making them impossible to monitor with a scanner. Analog cell phone technology, which could be scanned, is no longer in use.
What type of antenna should I use with my BC125AT?
For portable use, a telescoping antenna can improve reception over the stock antenna. For base station use, an external antenna mounted outdoors will provide the best performance.
How do I reset my Uniden BC125AT to factory settings?
Turn the scanner off. While holding down the “2,” “9,” and “HOLD” keys, turn the scanner on. This will erase all programmed data and restore the factory defaults.
How do I use the “Close Call” feature?
Press the “FUNC” key, then press the “Close Call” key (usually labeled “CC”). The scanner will then automatically search for nearby transmissions and lock onto them.
What does it mean if a channel is “trunked”?
A trunked radio system is a sophisticated system where multiple agencies share a pool of radio channels. To monitor trunked systems, you usually need a trunking-capable scanner. The BC125AT is not a trunking scanner.
Can I legally listen to police frequencies?
In most locations, it is legal to listen to unencrypted police and emergency service frequencies. However, it is illegal to use scanner information to interfere with emergency operations or commit a crime. Always check your local laws and regulations.
How do I update the firmware on my Uniden BC125AT?
Uniden periodically releases firmware updates to improve scanner performance and add new features. Check the Uniden website for the latest firmware and update instructions. You will likely need a USB cable to connect your scanner to your computer.
