Fleetnet inputs!?

[Josh]

VHF trunking is way different than 800 obviously due to there being no band plan for VHF like there is for 800.

Does anyone know what kind of split the fleetnet system uses? The canadian department of communications license search does nothing to assist me on the matter. I'm contemplating monitoring inputs but simply can't find 'em.

someone with "close call" has to know!

I dont know what you mean by split but I think you need this info to program Fleetnet...

hell yeah monitor those inputs. here's the spread. eg:

142.500 output, 138.480 input
142.260 output, 138.240 input

4.020 mhz spread.

Thanks for the info Frank, I'll give it a shot.

Interesting question. There are three non-overlappling input ranges in addition
to the output ranges listed; roughly 138-140 and the other two in the 148-156
MHz range. The -4.02MHz separation is common for outputs in the 142-143
range, but by no means the rule (a site near me uses several inputs above 148
MHz).

Inputs/outputs can be mixed/matched across the ranges as long as inputs are
in the input ranges, and outputs in the output ranges.

Anyone who runs an older version of Trunker can deduce what all the inputs
are. They are of no real use to most scanner users who only need to program
output frequencies.

No such thing as a split on VHF/UHF trunking.

System admin's can assign whatever input and output they want.

All they do is send the radio the output channel and input channel and the radio uses it's programming to determine where to transmit and where to listen.

A lot of channels use the old 4.020Mhz public safety split but several frequencies in my area use inputs in the 2nd range for outputs in the first.

You'll need to run trunker to determine what the proper input channels are.

I like to monitor the input frequencies when I hear encrypted activity, just to determine how close they are. If you don't have Trunker, an easy way to find the inputs, is to sit near a hospital that has fleet net ambulance service. You can monitor communications between hospital and ambulance, just using search function.

We get lots of out of town transfers here in Toronto , whether downtown in "hospital row" on University Ave. or near the TO borders like EGH ,Humber/Finch etc. so that may be a good idea.

And to look less conspicuous in front of the hospital(with your scanner) , have a smoke while hanging on to an IV pole. :twisted:
