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]].
It leaves a lot of the competition cold because of this feature, but also because [[http://wiki.radioreference.com/index.php/Continuous_Tone-Coded_Squelch_System CTCSS]] / [[http://wiki.radioreference.com/index.php/DCS DCS]] decoding is near instant and it features Close Call which is the most major breakthrough in scanner features of the last 20 years.

Uniden's dynamic memory system means that what would be previously considered as a 'Bank' is definable in size so that no empty channels occur and no memories are wasted. Similarly, groups can be defined within 'Systems' to allow even more flexibility.

'Quick Keys' are then used to easily select the groups you are interested in so a custom scan routine can quickly be devised to suit specific needs.

* Adjustable (0-5 sec) scan/search delay
Another advantage of this is that each channel has effectively a 48 character alphatag. It no longer becomes necessary to describe each channel in full as it is already qualified under a System and Group heading. This is similar in effect to a hierarchical structure as used in computer file systems and urls.

BR330T

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.
