Uniden DMA Scanner Frequently Asked Questions

What is DMA?

DMA, or Dynamic Memory Allocation, is a technique new to scanners. In conventional scanners, the scanners memory is partitioned into fixed banks of channels. While simple to understand and program, unused channels and banks are wasted in conventional scanners.

In most applications, scanners are programmed with several large trunking systems and a number of conventional frequencies. Often large trunking systems have hundreds of talk groups.

DMA makes better use of scanner memory by eliminating fixed limitations.

The downside to DMA is that it makes the job of programming the scanner much more difficult. It's impractical to consider programming a DMA scanner without a personal computer. To ease the task of DMA scanner programming, TrunkStar Elite and TrunkStar Elite Pro have been designed to simplify programming.

Which scanners are supported?

The Uniden BCD996XT/P2, BCD996T, BCD396T, BCT-15, BCR330 and BC246T are supported.

Which products will support the new DMA scanners?

Support for DMA scanners will be included in new products TrunkStar Elite and TrunkStar Elite Pro, as well as Spectrum Manager IX, Spectrum Sentry, Spectrum SentryNet, RMA-I and RMA-II.  Also, Spectrum Enterprise and Enterprise Federal.

What are the prices for the new products?

TrunkStar Elite will sell for $64.97 USD, and TrunkStar Elite Pro will sell for $129.97 USD. Both editions are available for electronic delivery only.

Are CD versions available?

CD editions of TrunkStar Elite and TrunkStar Elite Pro will be available from Scanners Unlimited at a later date.

What are the various features of TrunkStar Elite and TrunkStar Elite Pro?

TrunkStar Elite supports one DMA scanner and TrunkStar Elite Pro supports up to ten DMA scanners.

Both products support advanced programming features, conversion from group files (.SWG) and PC control.

TrunkStar Elite Pro has an advanced history list, additional logging features that track frequency and talk group usage by hit count and air time. In addition, the last twenty intercepts are stored for each frequency or talk group logged.

TrunkStar Elite Pro also includes a GPS status display (see below).

Will support for the Radio Reference Web Service be included?

Yes, TrunkStar Elite and TrunkStar Elite Pro include a new feature call the System Builder that uses the Radio Reference web service to retrieve system information.

Which product should I buy?

If you own only one DMA scanner, TrunkStar Elite is probably your best choice, unless you require the additional logging features of the Pro version, or you have a GPS-enabled scanner and wish to exploit the GPS features found in the Pro version.

If you own multiple DMA scanners, TrunkStar Elite Pro is the best choice.

If you own multiple DMA and non-DMA scanners or receivers, Spectrum Manager IX integrates support for both types of devices in a single software package. Additionally, simultaneous control of DMA and non-DMA devices is possible in Spectrum Manager IX.

TrunkStar Elite and TrunkStar Elite Pro both have free 15-day trial versions, so we encourage you to try before you purchase.

Are upgrades available?

TrunkStar Elite and TrunkStar Elite Pro are new products, so no upgrades to them are available.

Other upgrades to Spectrum Manager IX and Spectrum SentryNet are available. Click here for upgrade information.

How is DMA scanner information stored?

A completely new storage mechanism called a DMA Profile is used. A DMA Profile stores information about each system, site, frequency, talk group and location item that is programmed in a scanner. The DMA Profile also stores settings such as search ranges, SAME codes, etc.

The DMA Profile is structured in a way the reflects how the scanner save information. The user interface also reflects this structure.

DMA Profiles are stored on your hard drive as .SXS files.

Will I be able to convert group files (.SWG) for use with DMA scanners?

Yes, TrunkStar Elite and TrunkStar Elite Pro include a conversion feature that will convert existing group files created by other Signal Intelligence products (.SWG files) into DMA Profiles.

Additionally, other Signal Intelligence software products may include conversion tools to allow complete data interchange between Group FIles and DMA Profiles.

Can I do radio control with my scanner?

Yes, except for the BC246T. TrunkStar Elite Pro supports multiple simultaneous control sessions with full recording capabilities.

The BC246T is supported for programming only. This is because the 246 control protocol is missing key elements necessary to provide effective and reliable control.

Why is the signal strength column missing?

At this time, none of the DMA scanners provide a signal strength measurement beyond the number of signal bars. We have requested Uniden to provide a signal strength measurement (like the BCD796D and BC785D) in future versions, however it is unclear whether this will be technically possible.

Are the Spectrum Analyzer and Band Scope features supported?

No. Since there is no signal strength measurement available, these advanced features are unavailable with the current DMA scanners.

How are the location features of the BCD996T and BCT-15 handled?

Full support for location programming is provided in all software versions that support DMA scanners.

How is the GPS feature on the BCD996T and BCT-15 handled?

You can use a GPS receiver with the BCD996T and BCT15 while under PC control. On TrunkStar Elite Pro, a GPS status display is provided that shows position, time, speed, heading and altitude. This display is updated once per second.

If you have Spectrum Manager IX and have purchased the optional GPS feature, a BCD996T or BCT15 with GPS attached can be used as an alternative to connecting the GPS receiver directly to the PC. When this is done, the accurate time and position logging features can be driven through the DMA scanner. Note that there is an additional latency when doing this that might affect the accuracy of fast-moving drive-around measurements.

Are the wireless measurement tools of Spectrum Manager IX and Spectrum SentryNet available with DMA scanners?

No. Since there is no signal strength measurement available, these advanced features are unavailable with the current DMA scanners.
