Hi everybody,

I am still working on preparing my trip to Miami next month, and I came
acros this page
http://www.bellscb.com/cb_radio_hobb...leet_codes.htm
with info about the frequencies used by the police in Miami. I am a
little confused here. The website lists two frequencies groups:

TYPE I:

854.9625 855.2125 855.4625 855.7125
856.2125
856.4625 856.7125 856.9625 857.4625
857.7125
857.8625 857.9625 858.2125 858.7125
858.9625
859.2125 859.4625 859.9625 860.2125
860.4625
860.7125

and

TYPE II:

856.7875 856.9125 857.7875 857.9125
858.7875
858.9125 859.7875 859.9125 860.7875
860.9125

Since they are in the 800MHz range, I suppose that these are trunkated
frequencies, but what are TYPE I and TYPE II? My PRO-97 comes with the
following modes: CTCSS/CT, DCS/DC, Motorola/MO (pre-rebanding), EDACS,
LTR.

I am under the impression that TYPE I and TYPE II are probably
Motorola, but then how can I find out with these are pre or post
-rebanding (I think that my PRO-97 will not be able to scan rebanded
Motorola frequencies, alas).

Could I listen to TYPE I AND TYPE II at the same time? If yes, in
which order should I enter these frequencies in my bank? Do I also
need to enter the fleet IDs or does this receiver do that
automatically? (the IDs are also given on the web page above).

Many thanks in advance for your help,

VS

PS: for those who helped me with the Miami Sheraton frequencies
question:

I just came back from a chess championship in Orlando which took place
at the Traveloge in Kissimmee (South of Orlando). I used my PRO-97
Signal Stalker to scan for the hotel's frequencies. In less than 5 min
I had them all. The hotel's main frequency was 150.90500, but it also
used the following four 462.32500, 462.57500, 464.03750 and 469.03750.
In two days of scanning I did not identify any specific service using
any one rather than the other. Their main frequency, 150.90500, was
used for pretty much everything from calling in a repair to ordering
more towels. I did not identify any security frequency, but then
neither did I see any dedicated security personnel.

As promised, when I come back from Miami, I will post a short report
about the Sheraton there.

Hi again,

Now I am even more confused. I look up the autoritative radio
reference and I found out that according to
http://www.radioreference.com/module...=TRSDB&sid=208 Miami
Police does not use TYPE I or TYPE II Motorola, but *EDACS*?!?!

Which website should I trust?!

Radioreference says that:

-----
"Dade County actually has 3 separate systems in use for countywide
communications --

1. A 6 site 20 channel simulcast EDACS system for all public safety
operations.

2. A 6 site 20 channel simulcast EDACS system for all county services.

3. A single site 5 channel EDACS system for the Miccusukee Indian
Police, remote operations and aircraft operations.
This site is located at the Miccusukee Indian Reservation about 25
miles west in the Everglades.

4. A single site 5 channel EDACS system mounted on a remote trailer for
special operations and special events.

All Dade County public safety operations except the fire department
uses these systems.
A couple of Police Talkgroups are in AEGIS Digital mode or Encrypted.

866.06250 05 866.31250

-----

Does this mean that I should enter only the "public safety" frequencies
to hear the police? Since I am not from the USA am not sure if police
and "public safety" are the same thing or not. If not, which
frequencies do the cops (Miami Police & Sheriff) use?

Again - many thanks for any pointers!

This is the Dade County system. The City of Miami uses
http://www.radioreference.com/module...=TRSDB&sid=206. Since
the city is located within the county, it might seem confusing.

Miami city police are on the Motorola system. Dade County police are
on the EDACS system. I doubt that makes it any more clear to you.

Program both systems - you'll hear some action on one and some action
on the other.

with info about the frequencies used by the police in Miami. I am a

This has been upgraded to a Motorola Type II system - it's the Miami
City system. The control frequencies (the only ones you have to
program) a

854.9625, 855.2125, 855.4625 and 855.7125.
http://www.radioreference.com/modules.php?name=TRSDB&sid=206

TYPE II:

This is the Miami Beach system. The control frequencies a

859.78750, 859.91250, 860.78750 and 860.91250.
http://www.radioreference.com/modules.php?name=TRSDB&sid=207

frequencies, but what are TYPE I and TYPE II? My PRO-97 comes with the

LTR.

I am under the impression that TYPE I and TYPE II are probably
Motorola, but then how can I find out with these are pre or post
-rebanding

Everything at this time (with the exception of a few systems that have
moved - these haven't) is pre-rebanding.

Could I listen to TYPE I AND TYPE II at the same time?

No problem, since these are both Type II, but yes.

If yes, in which order should I enter these frequencies in my bank?

If you had a I/II mix you'd have to enter them in separate banks.

Do I also need to enter the fleet IDs or does this receiver do that
automatically? (the IDs are also given on the web page above).

You have to enter map information for Type I systems and for all
trunked systems you either enter the Talkgroup IDs you want to listen
to or you listen to them all.

I had them all. The hotel's main frequency was 150.90500, but it also
used the following four 462.32500, 462.57500, 464.03750 and 469.03750.
In two days of scanning I did not identify any specific service using
any one rather than the other.

Some of the 460 frequencies might have been trunked, and they don't
separate by frequency, they separate by talkgroup.

Hi Al,

Thanks for all the explanations!

Let's see if I got this right, ok?

First, for Miami-Beach and Miami City I program all the following into
one bank:

854.9625, 855.2125, 855.4625, 855.7125, 859.78750, 859.91250, 860.78750
and 860.91250.

and I tag each of them as "MO" for Motorola Trunking.

I ignore all the alternate control channels listed as "blue" on the
webpages you listed, right? (but then why would that be?! would I not
need them also?)

Since I want to listen to everything that is going on, I do not enter
and talkgroups IDs.

Should I want to listen to Miami-Dade *COUNTY* police I program EDACS
into another, separate bank. But which ones?! Are police "LG & Fire"
or "Public Safety"?

Also, say something big happens, how do Miami-City, Miami-Beach and
Miami-Dade County cops talk to each other?!

Any further pointers would really be appreciated!

Thanks,

VS

PS: I do not think that the hotel frequencies were trunked, but since I
was running only the Singnal Stalker mode I suppose I might not have
noticed. My impression was that there was no distinction made between
any talkgroups, pretty much everything was happening everywhere.

I would suggest you put the Miami Beach and City of Miami control
channel freqs in two separate banks. If they are in the same bank, the
scanner will monitor one or the other system, but not both. If they are
in separate banks the scanner will monitor one for a while, then the
other for a while, and if entered and turned on, Dade County for a while.

I suspect these systems are so busy you will be overwhelmed with calls,
and will find it difficult to sort them all out. You may wish to
'close' the banks and monitor only a few of the key talkgroups.

That depends. With GRE scanners and Motorola systems, you can program
more than 1 system in a bank, as long as there's at least one
not-locked-out conventional channel between control channel groups.

Really? So I could stack two Motorola trunked systems in one bank on a
PRO-95 as long as I stuck a "divider" conventional channel between them?
That's intriguing. Too tired to play with it right now, but I may
have to give that a go tomorrow night.

Set the mode for the bank as MO and the mode for each channel as MO.

Program 854.9625, 855.2125, 855.4625 and 855.7125 for the City, then
any conventional frequency (it doesn't have to be in use, but it can't
be locked out - 146.55 will work, if no hams are using it) then
859.7875, 859.9125, 860.7875 and 860.9125 for Miami Beach - assuming
you have a Radio Shack scanner.

Good idea, since there are none for either of those systems. (Black
is not blue.)

Since I want to listen to everything that is going on, I do not enter
and talkgroups IDs.

In the Dade County system, police talkgroups are listed in the Police
group - TGs 512-737.

Also, say something big happens, how do Miami-City, Miami-Beach and
Miami-Dade County cops talk to each other?!

Dade County, with their EDACS radios, can't talk to the others on
their Motorola radios. Miami and Miami Beach, being on different
systems, can't use those radios to talk to each other either. They
either have some interop system (a second radio) or the dispatchers
use the phones a lot. (They probably have direct lines to the other
agencies.)

People do it all the time, and it works.
