Uniden releases information on 800 MHz Rebanding Impact on Uniden Scanners.

Background Information
Beginning in the late 1990's, the FCC and industry began studying
interference problems on public safety communications systems in the
800 MHz band. The root cause of most of the reported issues was
interference from high-powered business radio systems on channels
adjacent to relatively low-powered public safety radio systems.

In early February 2005, the FCC issued a Report and Order directing that
certain actions be taken to reduce or eliminate the conditions that have
resulted in this interference. These actions include:

Moving current non-public safety licensees out of the 806-809/851-854 MHz
band. Moving public safety licensees into the 806-809/851-854 MHz band.
Changing the current 800 MHz channel plan.
The relocation of licensees should help to isolate critical public safety
bands away from interference-creating services, but will require that
users reprogram their scanner with the new frequencies.

The change to the 800 MHz channel plan will have the greatest effect on
scanner operation. Most scanners use this channel plan to determine the
voice channel frequency for Motorola Analog or mixed systems. Users with
scanners that rely on this channel plan will need to reflash their scanner
in order for it to continue to properly track Motorola Analog or mixed
systems. Scanners that cannot be reflashed will need to be replaced.

These two changes (relocating licensees and changing the channel plan) are
together referred to as "Rebanding."

More information on Rebanding can be found at http://www.800ta.org and
 from the links on that site.

Impact on Scanning Receivers
Rebanding is a mixed blessing for scanner users. The same interference
sources that have affected public safety users have also affected the use
of scanners, sometimes to a greater degree. Rebanding should greatly
improve scanner operation for the same reason that public safety radio
operation will improve: less interference from unwanted sources. However,
as rebanding occurs on a system, scanners will need to be replaced,
reflashed, or reprogrammed in order to continue to track the trunked
systems in the 800 MHz band. The following table summarizes this impact on
Uniden's current product line.

End users will be able to reflash the indicated models using a PC cable
and a software download from Uniden's web site. All future Uniden
trunktracking models are expected to either incorporate the Rebanding
requirements or be flash upgradeable to do so.

The first public safety systems could be rebanded as early as April 2006.
Uniden's goal is to have a firmware update available for each compatible
model by this time, but final testing and release of the update will
depend on the actual implementation of these changes. Uniden plans to
announce firmware updates for each model as they
become available.

This statement is based on the current rebanding plan, as accepted by FCC
and industry. Future changes to this plan could affect Uniden's response
or its ability to respond. Nothing in this statement should be construed
as any type of promise or warranty. Uniden reserves the right to make
changes to its rebanding response
policy at any time.
