Im looking for the input frequancies used by fleetnet. These are the trunked input frequancies, I am aware that the signal is repeated through the individual repeaters but I wish to monitor the actual TX freq from the cars.

Hi gary123 , you know how some Fleetnet sites were the old NOR system ?
Well, the database here shows the inputs if you choose that option.
Have a look at this list. It will get you started.


141.39000 = 139.47000
141.19500 = 139.18500
141.30000 = 139.95000
141.43500 = 139.15500
141.69000 = 139.45500
143.65500 = 139.06500
141.63000 = 139.26000
141.40500 = 139.09500
141.70500 =139.11000
141.49500 = 139.29000
141.36000 = 139.21500
141.72000 =139.48500
141.45000 = 139.20000
141.54000 = 139.30500
141.55500 = 139.32000
141.67500 = 139.35000
142.36500 =138.34500
142.66500 =138.63400
143.10000 =139.08000
143.16000 =139.14000
143.64000 = 139.50000
142.83000 =139.39500

If you run T88, Trunker, UniTrunker.. whatever, and have the hex channel numbers for the inputs you can determine the frequency with:

- Convert the hex channel # to decimal
- multiply by 0.015
- Add that value to 138.015

And, I may as well list the other way too. If you have an output channel#:

- Convert the hex channel # to decimal
- subtract 380
- multiply by 0.015
- Add to 141.015

This may vary in different Fleetnet zones, but it works in zone 1 using the standard base/step/offset.

The NOR frequency list is good to a point, however, Fleetnet has many
more pairs. Pairing varies by site; the same output can be paired with
different inputs. Also, the -4.02MHz offset in the 142-143MHz range
holds much of the time but there are lots of exceptions.

Not only this; outputs in Range 1 (141-144MHz) are sometimes paired
with inputs in Input range 2 (148-150MHz). There are several cases in
Zone 2/Ottawa; I don't know too much about Zone 1 but suspect it
is similar. The input base/offset 138.015/0 doesn't work for these cases.
For Range 2 input channel numbers above 132(dec), use 148.015/133.
I'm ignoring input Range 3 as I have not seen it used so far.

The original Trunker m3.8.3 before Eric Cottrell's recompile for VHF/UHF
systems will display both input and output channel numbers, but cannot
automatically fill in frequencies; they need to be calculated and entered
manually. It also does not properly interpret datastream for Fleetnet calls,
but is otherwise useful.

. Older versions of TRUNK88 appear to log input channel numbers
but (to my knowledge) does not display them. I'm not sure what UniTrunker
does but does not normally display inputs (if at all).

I agree DaveH there are different inputs for different sites even though the output freq is the same. Thats actually what started this thred. I heard activity on a freq that was not in my list, now im compiling the inputs for my local tower.

143.310/139.440
more to come

I forgot to mention, Treport also displays input channel numbers.
Watching the Ottawa site: input to 142.245 is channel 0xc6
(198 dec.). Since it is above 132:

Input freq. = (198-132)*0.015 + 148.015 = 148.990 (which it is).

BTW in Zone 2, the input to 152.000 is 148.795; is it the same
for Zone 1 (Mowat)?

Here are the other inputs for my local tower 33

142.140 /138.120
142.305 /138.285
142.740 /138.420

as said and suspected the inputs follow the 4.02 meg split for the 142/138 freq band I wonder if the inputs can be added to the WIKI?

Perhaps it would be interesting to compile the inputs for the whole system?

Besides that this info is not needed/wanted by most scanner users, I don't
think it's a great idea to publish it. Not questioning your motivation, but there
are people who could misuse the info. I've given info on how to find it if you
want it and a few bits and pieces but that's as far as I go. My reason for
wanting to know is just to identify stuff I run across when I'm searching.

in Zone 2, the input to 152.000 is 148.795; is it the same for Zone 1 (Mowat)?
On Mowat, the input for channel 597 (152.0) is channel 212 (149.2 if my math is right)

Oh BTW, one of the input channels on Cedarwoods is #280, which I assume puts it in the third input range. Anyone care to share the base frequency? (I assume the offset is 266)

I believe the third range starts at 150.0650Mhz which should be offset 269 by my rough calculations.

That would mean Channel 280 is 150.2300Mhz which was the old input to the Kitchener-Waterloo conventional channel of 154.7700Mhz.

If range 2 covers 148 to 150, wouldn't its highest channel be 265/149.995?

I would've though that range 3 would start with the next channel number. 266/150.020 puts channel 280 on 150.230, so for now I'll go with that unless someone knows for sure.

Yup, just redid the calculations and you're right.

Range 2 ends at 149.9950/265, Range 3 begins at 150.010/266.

Not sure how I goofed up the starting channel but somehow I still ended up with the right frequency.

My head is starting to spin.

Range 1 starts at 138.015mhz/Channel 0 and stops at 139.995Mhz/Channel 132.

Range 2 starts at 148.0150Mhz/Channel 133 and stops at 150.040Mhz/Channel 265.

Range 3 starts at 150.065Mhz/Channel 266 and stops at 151.715Mhz/Channel 379.

Excel shows 150.2300Mhz/Channel 280.

Hopefully I've got it right now.

Oh vey.

Check.


Range 2 starts at 148.0150Mhz/Channel 133 and stops at 150.040Mhz/Channel 265.
I get 149.995 for channel 265.


Range 3 starts at 150.065Mhz/Channel 266 and stops at 151.715Mhz/Channel 379.
I get 151.760 for channel 379.


Excel shows 150.2300Mhz/Channel 280.
I get 150.275 for channel 280.

Personally, I blame it on Microsoft.

This is what I come up with using your base frequencies and starting offsets:


Range 1:

000 138.015
001 138.030
002 138.045
