Port Dover, ON. Frequencies Needed

[mciupa]

151.820 == 155.715 ONTARIO-WIDE (ML RPTRS) The Province of Ontario (GMCO)
151.820 == 155.715 TORONTO, ONT.(VHF ML) EMS Division

Who knows (about) these ones?

These are two defunct freq's.
The ONTARIO-WIDE was used by London CACC until they went over to Fleetnet . The TORONTO one was the NE quad freq. until the changed over to EDACS trunking.
155.715 would have been the input to 151.820.

153.8550
148.3850
155.7250

I think you need to adjust the frequencies to fit the bandplan:

153.855 should either be 153.860 or 153.845.
148.385 should either be 148.380 or 148.395.
155.725 should either be 155.715 or 155.730.

141.6750 is probably off the Simcoe tower.

Just wanted to say in (somewhat) defense of not getting the exact frequency,
the VHF high-band can be confusing. When not sure of the exact frequency,
best to search TAFL with a small frequency range. You can also discover
interesting things by accident.

For example, 138-144 and 148-150 (approx) in Canada is 15kHz steps,
but 12.5kHz in the U.S. In border areas, the frequencies only sometimes
line up. In the 150-162 bands, there is a mix of 15kHz (Canada and US);
and 25kHz in the marine 156/157 and 161MHz sub-bands.

To add confusion, there are some step "discontinuities" around 150MHz
(due to a satellite sub-band 149.900 to 150.050) and another around
154.50MHz (reason unknown). Over time you get to recognize what the
"good" frequencies are, but it can take awhile.

Further, some frequencies seem to be allocated "off the pattern" for
some reason. Some of Hydro-Quebec's 150MHz channels are like this
(150.790 v. 150.785). Another is Cornwall/area EMS on 150.685 ("should"
be 150.680; or 150.695, which is allocated in S. Ont). And there are others.

Now, I can hardly wait for narrowbanding, 6.25 and 7.5kHz steps.

I know that America has started using narrow-banding, any idea when
our agencies will follow suit ?

I believe it's already in use.

The tech for Bradford FS told me that they were close enough to Toronto that their new system would have to be narrowband.

Now that they're on the air, I forgot to ask him if they had to go narrowband.

No particular large "agency" that I know of yet, but all new licenses in areas including Ottawa would most likely be narrowband. I see business users starting to slowly switch over. TimeMCI's UHF MPT-1327 system has been narrowband for at least a couple of years.

When searching TAFL, I always enable "Necessary Bandwidth" and "Class of Emission". If you see 11.0 or 12.5kHz, versus 16kHz, along with F3EJN, it's narrowband voice.

I did a quick lookup on Bradford FD and it's a mix of 16kHz and 11kHz; probably during the transition. OFM channel 154.070 is wide, may stay that way for a while?

I'd guess OFM fire will always be wideband since their will probably be areas that won't have to switch to narrowband for quite some time.

It's always a good idea to leave common channels at the lowest common denominator which would mean no signalling, analog and wideband.

Thanks for the tip on narrowband finding on TAFL. Looks like Bradford fire is narrowband on their new repeater while the County Mutual Aid frequency and OFM stay wideband. Now to look at a few other licences.
