1. What does a simplex frequency means?
2. I was looking in a site with frequency listings and cities with a lot of PD and FD frequency(let say Ottawa) had ''F'' then a number. What does it mean?(http://www.panix.com/~clay/scanning/frequencies/canada/ontario/general.txt)
3. What is the difference between a local frequency and a F1 like for North Bayy FD? the same site as no. 2 has been used.

Simplex means there is one Frequency in the system. "Im talking and you can't talk until I'm done"
Duplex means there is a repeater involved with two Frequencies one input and one output. we both can talk and recieve at the same time. Kinda.

All that F means is Frequency or Channel ie: CITY POLICE F-1 Dispatch, F-2 SWAT, F-3 Dog Catcher, etc.

Hope this helped

Sorry should have included that Simplex is very low power. Limited distance, good for Fire Scene / Crime Scene Communications. On fire scenes it is sometimes better to just yell out the window.

Back in the old days radio shack put out a book that told all about radio communications, all I remember about the book itself was the fact it was blue, there was a section that was dedicated to types of mobile antennas, and other basic stuff, well the book is gone and all we have is the internet and a little site called wikipedia, I found this page that seems to discuss radio systems, here you go enjoy

Not necessarily true...there are still lots of VHF licensees with up to 100W ERP
(possibly more) running simplex over wide areas e.g. towns and cities.

What type of scanner do you need to be able to listen to talkgroups? Any suggestion (I don't want an expensive one)? Also with the scanners that can listen to talkgroups, can they also scan them? With my scanner I cannot listen to talkgroups and I'm thinking of bying myself a better one. Anything else tht I would need to know before making this purchase?

Please advise and thanks.

It is a ripoff of the old Scantrix frequency list, complete with the "COMMERCAIL" typos.

I see Scarborough Fire uses 154.430. Not. That list is a huge waste of time.

There is a wiki here that tels you which scanner(s) scan what.
There are for sale and wanted forums here.
There are threads devoted to uniden and GRE and R/S scanners.

If you want to listen to your EMS you will need a trunk tracking scanner analog.
If you want to listen to the OPP you will need a digital P25 capable scanner.

As for price... you get what you pay for, either go big or go home. Like many people have explained to you in previous forums the scanner you have now does jack squat. There is very little point in trying to scan the EMS using your scanner.

I think thats what you need to know.

Robin: Whatever floats your boat is cool but:
You cannot possibly be able to follow the voice comms on a trunked radio system.
Both the OPP & MOH have vehicular repeaters, so if you are in the area of a 'unit' you can hear stuff but you are honestly missing out on the scanning experience with your regular scanner.

Youre better off tapping the scanner you have, and putting a few bills down on any of the scanners mentioned in the wiki articles or on forums here.

I am wondering, with the Uniden BC 246T, would I be able to listen to EMS and OPP freq. and talkgroups listed in the Bell FleetNet - Gov. Zone 3 list? The system type is Motorola Type 2 SmartZone witch is supported by the 246, however, the voice system is analog and APCO 25 Common Air Interface. Si will I?

A 246 will do well enough to hear whatever EMS talkgroups you want albeit from what I rememeber the audio on it for VHF Hi was poor.
You will not hear any APCO 25 comms, only digital noise as the 246 does not handle digital comms.
OPP-You will hear vehicular repeaters if your area has them (I wouldnt even know where timmins is on a map) but not talk groups because you cannot hear digital comms on a 246.

What EJB said above is correct as far as I know as well.

As posted in the OP's other topic ...
the 246T should get everything you want OTHER then OPP which are digital. You can get their SIM and vehicle repeaters but thats about it.

Other then that the 246T is a nice addition will do almost everything else your looking for.
If you NEED OPP then you have to look into a digital scanner Uniden 250D (with card) 296D 396T 396XT GRE PSR-500 Pro-96 Pro-106 (all the handhelds)


You mean Scarb Fire isnt on 154.430? Crap Ive been sitting on that channel for the last 8 years waiting for a fire call to come j/k (that was a joke)

Is it just me or trunk tracker scanning look verry complicated from the conventionnal scanning. Is it easy to understand? Can eneyone give me a link for and introduction to trunk tracker scanning? I'm doing a transition from conv. to tt scanning and I want to understand it before I buy a analogg scanner.

Here's a place to start in our Wiki here:
