Sound Card MDT decoding in Phoenix (Yes, it does work, folks)

Sound Card MDT decoding in Phoenix (Yes, it does work, folks)

Post by Phil Smalle » Thu, 26 Nov 1998 04:00:00

Ohhhhhh boy, do I have some news....

I did manage to get the program to run for me finally (works on my laptop,
but not my desktop PC - soundcard is hosed, D'OH!) and it works
sensationally...

For all you fellow Phoenix scannists out there, I have good news and bad
news. First the bad news (for me at least, maybe you won't care):

Phoenix and DPS MDT's use what sounds to be 19.2 (Could be 9.6 but it sounds
alot faster to me - just an educated guess) so this program won't do it.
However, if I do locate (hint, send it if you have it) the spec's for that
protocol, I should be able to hack the provided source code and come up with
a decoder for us in a couple of months (Unless Gordon wants to tackle that
one too - if so you've got a beta tester right here). But now for the good

It works for:

Glendale PD on 856.2125
Scottsdale PD on 854.9625 (I think, Check the SWFD for the exact freq)
Tempe PD on 855.2375

Oh boy, does it work. Just wait until you try it - you won't believe the
stuff they send out on those MDT's! I'm talking about drug busts being
coordinated, call details you'd never hear over the air - how about the
phone number of the caller, for starters? Plus calls for service that don't
get broadcast (saw one last night that said the bad guys had a scanner. Can
you imagine if they had a computer too? D'OH!) How about the ability to not
only intercept a wants/warrants check on someone, but send that screen to a
FILE?? Plus, just being able to *read* a call as it's being broadcast, now
that is just the coolest thing ever.

 I have to admit this is my second day on practically no sleep. I feel just
like I did when I got my first scanner -  I'm hooked. Gordon, keep up the
great work, and tell Motorola to suck an egg if they come knocking. I don't
see why they should care, they could just shrug their shoulders and sell
their customers a new mega million dollar 19.2 system (but damn, I sure hope
not!)

Tomorrow I'll be spending turkey day in the East Valley, so I'll report back
on Chandler and Mesa's systems, unless someone wants to try them today. If
so, email me with your findings.

 I really hope I can get Chandler's to work, because they arrogantly claim
it can't be done. See:
http://www.primenet.com/~chandler/html/service/police/freq.htm.

 I won't do this (and neither should you, if you like to monitor MDT), but
wouldn't it be funny to send them an anonymous package containing a print
out of that page, printouts of one whole day's MDT traffic, and a note that
says "oh YEAH?!?!?" Ha, ha ha ha....that'd be HILARIOUS.....

Happy monitoring!
-Phil
