sucks. Try to find an old recording from at least a year ago.

The OLD NYPD consoles were custom built for them and did things like
operate full duplex allowing the units to cut off the dispatcher as
s/he was talking and have the dispatcher still hear the unit
(something that most manufacturers *still* haven't caught on to...).
The famous 10-13 tone was the weighted "DAH" side of a morse code
iambic keyer. Sounded like morse TTTTTTTTTT
The new tones (as heard on police scanner.com and on the air now) are
much shorter in duration and sounds like the "DIT" segment. Sounds
like slow morse code EEEEEEEE. The tone freqs. varied as components
devalued in the circa 70's tone remote consoles. Typically from 700 -
1200 Hz.
You can make these tones up with a cheap and simple morse code keyer
and don't need to record them.

Afraid you've got me to blame for that one. Early in my nyc-ems career I
got annoyed (and a bit scared...) when I realized that field units could
hear each other over the dispatcher (sometimes...) but that the dispatcher
couldn't.
So.. I wrote to Uncle Jim (James T. Kerr, then executive director of EMS).
A couple of months later he wrote back to me saying that "voted radio" (I
still remmeber his use of that term... hmm... now that I think about it,
there are only two people in the agency who could have written that letter
for him...) was being fed, full time, to a low volume speaker near the
dispatcher.
>(something that most manufacturers *still* haven't caught on to...).
The more things change...

What ever happened to James T.? Does his alterego still do the morning
show on WPLJ?

if the dispatcher has the headset on she can hear u on the recieve side
of the voted audio. when they dont wear the headset the voted audio is
heard on the unselected speaker side of the console.
all the changes took place when they went from the old bramco consoles
to the motorola centracom console.
and the process is commonaly called 4 wire audio. the voter is in
queens. the audio from the voter goes to metro tech thru the console
then out to the repeater.or when the dispatcher steps on the ptt it
goes to them and units in the field hear them selves through the
unselected audio feed. i am still looking for a copy of the new or old
13 tone if anyone can help me out it would be greatly appreciated.

I think Scotty finally beamed him up.

Yes, but it wasn't true when Embassy system went online.

When they built the CC-II with the Embassy switch, there was an issue
Motorola LMPS Large Systems had to deal with:
Normal CC-II configuration was that the transmit channel is muted
while the dispatcher is keyed. After 11 Metrotech went online, the
COIM board had to be reflashed with SP firmware to emulate the duplex
operation of the Bramco consoles, not only with unmuted 4-wire audio,
but to emulate a distinctive 10-13 alert tone that did not sound like
the customary Motorola (slow) beeps, steady tone or warble tone.
Simply supplying four-wire audio just means there is a non-hybrid
full-duplex path. It doesn't speak to what the console does with the
audio.
You can build a simple circuit from a Curtis 8044M CMOS IC that will
let you play 10-13 all day.

This guy was a trip! He was from BRAVO.

that with the plain old ccII it was just a matter of programming and a
jumper on the bim card. as for the sound qaulity of the system, i like
the way the new console sound if the dispatcher talks on it properly
there are many times when u have to tell them that they are coming in
2x2 or there putting there mouth right on the mic which can be annoying
at 4 am. and sometimes the use the wrong button and hit the radio when
they are trying to use the telephone through the console.

I like your idea! That really gets attention.
Let me scan it in and I'll send it to you as an attached jpg.

The Boston Police always had that system, but it took us a lot of kicking
and screaming to get it for EMS dispatch. The first version we got put the
audio into the dispatcher's headset, but didn't repeat it if the dispatcher
was talking. The second version put it into the dispatchers ear and over the
repeater. So, if a unit is in trouble or has priority traffic, they can
break into the dispatcher's broadcast.
