Default Questions about Minitor Pagers (VHF) (154 mhz)

I may be doing some free lancing in the near future and wanted to
ask a few questions about a Minitor 2 vs Minitor 3 radio pager
unit.

This would be operating in the 154 mhz band with 2-tone paging.

From reading various articles in the past I got the impression
the Minitor 3's were synthesized units, and were disasters
when they were 1st placed into service by Motorola. Is this
true?

Is there a Minitor 4 pager available?

Should I try and buy a new unit or clean used unit? Any information
appreciated.

Thanks.

I'm thinking Ken was talking about some media work or photography, not
actual firefighting.

Minitor II's used tone reeds... now sometimes difficult to get, and
prevented you from quickly changing tones.
III's are synthesized, and pretty much non-existant. IV's replaced them
quickly, never did get the real scoop, but I think it was a
manufacturing issue.


Ah - the III and the IV are effectively the same radio. The difference
is that the IV has a better mode switch and different case. Everything
else is the same. There are sensitivity issues, but many people wrote
that off to synthesizer noise. I've got a IV and it decodes below the
squelch level.

IV's are out, and now so are the V's. We use IV's, UHF tho, and havent
had a single complaint with them. They are available in a variety of
flavors, with/without stored voice, vibrate, 2 channels, etc.


I've only prepared specs for the Minitor V as in eight years all of
the others may end up working unpredictably after narrowbanding
(mandatory on VHF High band and UHF after Jan 1, 2013).

Yes - video.

I was told today (radio shop) that many Minitor 11's are still
in service here in my county. They have a digital trunking
system, but also simulcast on VHF (fire) for the volunteers,
for paging.

We used to call that "stringing." Used to close down a couple of bars
with some stringers in NYC like 20 years ago. Did a lot of buffing and
found this weird culture of who can get the best shot going on during
"tour 1" (midnights).

Are you taking digital video? Once upon a time I was getting ready to
buy a Cannon L1A Hi-8. Didn't do it, though. Bought a Sharp consumer
grade Hi-8, but everything went digital shortly after. I tossed a
couple of U-Matic, 1/2" and 1" reel to reel machines a while ago.

I can't get people to sit through my home or vacation videos, anyway.
The camera's been packed away for years and we only take stills for
vacations and special events now.

There's nothing wrong with Minitor II pagers except that Motorola has
deliberately stopped making certain parts available and are calling it
"no longer supported." If you have one in good condition it'll work
fine.

Well, 2013 is a deadline for narrowbanding anything below 512 MHz.
EVERY VHF system which is currently not narrowband will have to be
modified. Many alerting systems will continue to work, but with
decreased range. Some alerting systems will not due to an extremely
wide range of tones in use within the system. The Minitor V has a
programmable ability to work in narrowband mode whereas the others do
not.

Yes. I just bought the Sony camcorder one week ago!

It works well and looks great on TV. I shot a video yesterday
of an SUV "trying" to drive into someone's apartment living
room in Gaithersburg, Md. This is a costly investment but
I wanted a 3-CCD chip camera so the colors would look good.
You can buy a Mini-DV, Digital 8 or DVD camcorder for $400 to
$800 that look just fine.

I may very well end up with a Minitor V.

I'm the radio and equipment officer for a 30 man Fire and Rescue department
in North Carolina, using vhf, 154.355. We average buying about half a dozen
new pagers per years to replace old/defective/lost pagers.

2's were good radios, but crystal controlled, reed controlled tones.

3's were junk, therefore not around long.

4's have also given us a lot of problems, losing programming, stop alerting,
etc. I even have the programming hardware and software for them, and still
end up having to send them back to the service point for repair.

I was just about to start looking outside the Motorola world for our next
bunch of pagers, but guess will give the 5's a try first.
