From The RadioReference Wiki


The Uniden Bearcat UBC3500XLT is a Europe marketed scanner from Uniden similar to the BR330T USA version. It can scan conventional analog frequencies only, and features 2500 memory channels organized with Uniden's Dynamic Memory Architecture.

Although trunk tracking is not supported by the scanner itself, the radio is steerable by PC and Trunkview has been shown to work with the UBC3500XLT. This allows it to track MPT1327 trunked systems.

Steps and Frequency Resolution

The UBC3500XLT claims in its specifications to be able to deal with 6.25kHz steps although its frequency only gives four decimal places. To my knowledge, it is incapable of tuning exactly to 6.25kHz offset channels as for instance used with PMR446 radios although in practice, this does not affect the listening quality.
