i have a pro97. my questions are 1: is this available in the US? and, 2:what do i need to monitor this? thx

The PRO-97 won't do it - in fact there are no scanners that I know of that can. There are a few of these in the US. There are 2 ways to monitor this mode;

a. Use software listed in the Trunked Radio Decoders article (Forum Specific Topics section on our wiki) - UniTrunker can handle it, and there are a few dedicated software packages, too;
b. Winradio has a trunking option that is supposed to work with Moto Analog and MPT1327 systems. You can find the link for Winradio, and it's various pages, in our Scanners, Receivers and Professional Radios section under 'PC based receivers'

How well these packages handle it I haven't a clue, as we don't have any MPT1327 systems around me I know of

1: yes, it's available anywhere in the world and there are an increasing number of users in the USA
2: your scanner.

It is possible to monitor an MPT1327 system with your scanner only by programming the voice channels into memory and scanning them. There are several software packages available ranging from the free to the expensive. The best free one is TrunkView but at this time it does not support computer control of your scanner (contact the author - he'd probably be willing to work with you to get add support). The best (expensive) payware is FTrunk but I can't remember offhand if that supports your radio (but again the author is very active and willing to consider adding features/radio support). In between there are all sorts of other pieces of software some of which are good but most of which are quite limited in functionality.

Software control of your scanner for MPT works in much the same way as the common software used for Smartnet monitoring in the USA.

Further to Mike's reply: Unitrunker MPT1327 support is VERY limited but it might currently be the only software that would also suppport control of your scanner.
Winradio trunking software (yes, it's software not the radio itself) looks pretty but isn't as fully featured as things like TrunkView, FTrunk or TrunkSniffer Pro

hey thx for the replies.. i may need to get walked through all this. im new to using programs to scan.
im not sure if i can remote control my scanner (pro97) from my computer. i dont know about any data slicer gizmos, etc, lol.
what freq ranges would i find voice freqs?

dwilson48625 · #6 (**permalink**) 09-16-2007, 05:47 PM

email: trunkview@linato.net

or view the website at www.linato.net/trunkview

It is my understanding that most of the Radio Shack scanners are not capable of PC control by ANY program.

However, Trunkview can be used to decode the Control Channel data-stream, and does not require a discriminator tap or data slicer, just an audio cable from the scanner Speaker/Earphone socket to the Soundcard Line In or Mic socket.

Difficult question to answer in a few words, or sentences, and it depends on how the site is set up by the system administrator. Some systems are set up with the bare minimum functions enabled, and others seem to have every possible option enabled.

Probably the main items of interest displayed are:-
The system ID (SysID).
GoTo Voice and GoTo Data messages, which will also include the Channel Number and frequency of the GoTo channel (if the "Base frequency" is setup correctly).
Registration requests.
Will decode, and display, some HEAD messages, if they are used on your system.
'Announce control channel' messages. Used to advise units of the control channel at other Sites, or if the control channel on other Sites has changed. (Some Sites change the control channel multiple times a day - don't know why). There is also a 'Withdraw control channel' message which is used if a channel is no longer a control channel.
On Sites with changing control channels, a 'Move' message is displayed, showing the new control channel.
System status messages.
'Vote now advise' messages, which give the control channel number of adjacent sites.

cool. thx for the info

Will the nwe Gre PSR-500 scanners decode this system?

Thanks,

There are currently no scanners that natively "trunk track" MPT1327 systems.

Read the previous replies to the original post in this thread.

Which I cant believe seeing how many MPT systems are out there. Its also an open protocol so its not like the scanner manufactures would have trouble writing it in.

I suppose the main reason is that until recently, MPT has been kept out of the USA, even though its been around since the 80's in Europe and just about every other country in the world!

This is almost certainly part of the reason but not the whole story. It seems as though certain well known scanner manufacturers chose not to look at it BECAUSE it was an open protocol.

Hu???

I would guess it is because of the relatively small number of interesting to listen to (public safety) systems on MPT in the largest scanner market in the world (USA).

So if it confused you, did you bother to establish that;
1) the source is in a position to know,
2) the source in a position to tell you,
3) the source is not giving you a "go away" answer?

Why believe (and repeat) information that makes no sense?

What makes no sense is this sidebar. A careful read of both yours and morfis' comments reveals that you two are discussing two different views of the same statement; both of which are off topic. Drop it.
