[TheList] Interesting P25 info

Tue May 18 11:34:51 AEST 2010

The focus of the data seems to be two things, the first is that Software
Defined Radios (in this case the USRP <http://www.ettus.com/products>  and
the OP25 <http://sedition.org.au/op25/wiki>  project) are now being
harnessed to monitor (and one day build) P25 systems. The second is that
Amateur radio operators are embracing this technology overseas and efforts
are being made to "re-band" commercial radio equipment to create P25
networks for Amateur use.

We will probably (never say never) not be able to monitor police voice
traffic the way we used to, that window seems to be rapidly closing for the
general public at large. Monitoring traffic and traffic analysis (who's
talking to whom or who's talking the most and their location) may well be
possible with some of these tools. Add to that the probable migration of
other first responders who may not utilize encryption to the new radio
network in the future (fire and ambo) suggests that over time these new
tools may become more valuable.

So I think that one major door is now closing for our hobby, but it looks
like for those who are interested and up to the challenge a new door might
just be opening.

Scanhead.
