Programming Conventional Channels

Each of the scanner’s banks can hold a mix of conventional channels plus one trunked system. This section describes how to store known frequencies into conventional channels.

You might want to gather all information about the systems you want to monitor before you start to program the scanner. The “Conventional Scanning Worksheet” included in the help file included in the demo software (download at http://www.uniden.com) makes this easy.

The first few sections are intended to be performed in the order indicated if you are entering information the first time. If you are editing existing information, manually select the channel then follow the steps in the appropriate section to access the information you want to change.

Programming conventional channels is easy - just select a channel to program, enter the frequency, then press E.

Important: Do not use this method to program trunked systems. They require additional information to scan correctly. See “Programming Trunked Systems” on Page 41 for more information.

Changing the Frequency Step

The channel frequency step option controls the frequency step size used when you manually tune up or down from the frequency stored in the channel. Your BC898T is preprogrammed with the most common step sizes for each band, so you seldom need to change this setting. To change the frequency step, press MANUAL then repeatedly press STEP until the frequency step you want flashes.

Note: If you select a 6.25 kHz step for the 150.0000 through 161.9999 MHz frequency range, the scanner will actually use a 7.5 kHz frequency step to match the FCC band plan for this range. However, the scanner’s display will show 6.25 kHz as the selected step.

Setting the Modulation Mode

Radio transmissions are modulated in several different ways.

The BC898T is able to demodulate the most common transmission types. Your scanner has the most common modulation mode preset for each band, so you seldom have to change this option. However there are occasional services that use a modulation mode that is not standard for that band.

To change the modulation mode, press MANUAL then repeatedly press MODE until the modulation mode you want flashes.
