Yes, Jeff sent me that off-list yesterday--interesting and something to be
aware of. I strongly suspect that for the prices Uniden is getting for some
of their better scanners these days, they'll have a ROM flash available.

Speaking of trunked systems, are you aware of the following?
800 MHz FCC Rebanding Action
Question:
Is there any impact on on Uniden Scanners due
to
the rebanding?
Answer:
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.
