WHat is searcHing? The UBC126AT can search for active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into the scanner. When you select frequency bands to search, the scanner searches for any active frequency within the lower and upper limits you specify.
understanding scanning What is CTCSS/DCS? Your scanner can monitor systems using a Continuous Tone Coded Squelch System (CTCSS) and Digital Coded Squelch (DCS) system, which allows the squelch to open only when the tone you have programmed with a specific frequency is received along with a transmission.
with a signal, the scanner’s squelch remains closed and you hear nothing. Refer to the Reference section of this manual for tables showing the available CTCSS frequencies and DCS codes. Conventional Scanning Conventional scanning is a relatively simple concept. Each group of users in a conventional system is assigned a single frequency (for simplex systems) or two frequencies (for repeater systems).
radios such as UHF-CB radios. The range is typically 1.5-12km, depending upon the terrain and many other factors. Repeater Operation Repeater systems use two frequencies: one transmits from the radio to a central repeater; the other transmits from the repeater to other radios in the system.
By itself, this manual really only provides part of what you need to know to have fun scanning – how to program and use the scanner. The website, www.radioreference.com, is the Internet's premier source for user-supported radio system information. This web sites is not affiliated with Uniden.
setting uP your scanner These guidelines will help you install and use your new scanner. If your scanner receives interference or electrical noise, move the scanner or its antenna away from the source. You might also try changing the height or angle of the rubber antenna. To improve the scanner’s reception, use an optional external antenna designed for multiband coverage.
Connecting an Optional Antenna The scanner's BNC connector makes it easy to connect a variety of optional antennas, including an external mobile antenna or outdoor base station antenna. Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is over 15m from the scanner, use RG-8 low-loss dielectric coaxial cable.
You can power the scanner using alkaline (ALK) non- rechargeable batteries (not supplied) or the included Nickel Metal-Hydride (Ni-MH) rechargeable batteries. [Uniden provides a USB cable to charge the Ni-MH batteries on initial installation and to recharge them through your computer or through a power adaptor that provides USB charge power.
• Do not use and charge Ni-Cd batteries; this may cause a safety hazard and damage the scanner. Installing Non-Rechargeable Batteries Make sure the power is turned off. Slide the battery compartment cover off. Use a pointed object such as a ballpoint pen to set the battery selection switch inside the compartment to AlK.
Note: To prevent damage to Ni-MH batteries, never charge them in an area where the temperature is above 45°C or below 4°C. Charging the Ni-MH Batteries The scanner has a built-in circuit that charges the included Ni-MH batteries when a USB cable connects it to a computer (NOT to a USB hub) or to an AC or DC adaptor that provides USB charging power.

PrograMMing cHannels Now that you have configured your scanner, you are ready to start using your scanner’s preprogrammed service banks, the custom search banks, the Close Call feature. You can also program your channel memories or re-program your 10 custom search bank memories.
The scanner automatically rounds the entered number to the nearest valid frequency. For example, if you enter 151.473 (MHz), your scanner accepts it as 151.475. If you entered an invalid frequency, Out of Band appears and the scanner beeps three times. Press . Clr and enter a valid frequency.

close call Using the Close Call Feature Unlike searching, which requires the scanner to tune to a frequency to check for a transmission, Close Call RF capture directly detects the presence of a strong, nearby signal and tunes to that frequency. Close Call RF capture works great for finding frequencies at venues such as malls and sporting events.
Close Call works better with some types of transmissions than others. It might not correctly display frequency information for transmitters using a highly directive antenna (such as an amateur radio beam antenna), if there are many transmitters operating at the same time in the same area, or if the transmitter is a broadcast television station.

Enabled search bands appear on the lowest line. Disabled search bands are not displayed. The currently searched bank number flashes. • To turn Close Call bands on or off, use the number keys (1-6) on the keypad. One search band must always be enabled. If you turn off all search bands, the scanner will display All Band Off! • To hold on a specific band, press Hold.
To cancel the hit, turn the Scroll Control. To temporarily lock out a frequency, press l/O. To permanently lock out a frequency, press l/O twice quickly. To store a frequency, press Pgm/E. See Storing Found Search Frequencies on page 51. To exit Close Call Only mode, press Scan.

dcs codes Birdies All radios can receive "birdies" (undesired signals). If your scanner stops during Scan mode and no sound is heard, it might be receiving a birdie. Birdies are internally generated signals inherent in the electronics of the receiver. Birdies are especially present at the 16MHz level (Internal CPU clock).
