[Scan-DC] MPD P25

How about the fact that **every** radio transmission can now be idenified.
Under the old system, there were many Midlands and older Sabers that did not
have a radio id.  Under the new system, every radio does have an id.  Not
only do they all have ids, but the portables display the ids of the
transmitting radios.

We just completed a project with the MPD SOD the
week before last.  They were using the new radios.
One reason why the officers may seem to be a bit
more "courteous" could be because when you
transmit, you have to wait a second or two before
you start speaking.  This is enforced by an
audible tone that starts when you key the radio.
Then you must wait until the tone stops before you
can start speaking.  Maybe the system is forcing
the user to wait for "clear air" before he/she can
transmit, rather than just cueing up a repeater.

Good morning.  I do appreciate David
Schoenberger's report on MPD's new digital system.
I am surprised on how fast DC implemented the
switchover with very little fanfare.

I finally got the system programmed on my BC785D
last night based on Dave's reporting. I wonder if
they will establish talkgroups to replace the
Citywide, SOD, and the old Command/Station
channels.

I am also surprised on the radio discipline now
being employed between officers and dispatchers.
There seems actually to be actual dispatching
going on as opposed to the "free wheeling"
approach taken before when units would cut each
other off, assignments were given to any unit that
would answer, and a general rudeness and chaotic
situation ruled.
