Subject: The Real Cellular Phone Frequencies?
Organization: University of Colorado, Boulder
Date:  8 Sep 92 23:01:44 GMT

I am new at this scanner business (just bought a Pro-37 on sale at RS)
and am a little confused about cellular phone frequencies.  Searching
frequencies on the 851.1125 - 868.9375 MHz band, I hear conversations
that sound for all the world like phone conversations, including the 
sound of numbers being keyed in and phones ringing.  

What then is on
the 870 - 890 MHz band which is locked out at the factory and that the
published mods restore?  Does my Pro-37 cover a fraction of the current
cellular band and the mods simply restore a small fraction that wasn't 
originally covered?  Just how much traffic does 870 - 890 MHz get relative 
to what I can already access?  Do I really want to practice soldering on
my brand-new $200 scanner? :-).    

Thanks!

I would very much like to know if there are an sites where I could find
scanner lists.  I looked at the book from Radio Shack, but it does not
have all the frequencies whichh exist in my area.  Thanks!

OK, guys, help me out here... President Bush was in town here this
weekend, but try as I might, I wasn't able to hear any radio traffic
on the Secret Service/U.S. Marshall/FBI frequencies I have (162-167 MHz).
Nor was I successful at finding any on my own... Luckily, the local
PD was using one of their frequencies as a "detail" channel, and I
was able to satisfy my curiosity that way.

What gives? I'm sure they must have been doing a significant amount of
talking... Are they using some military band frequencies (which I don't
have)? Had I actually been able to pick up anything, would they have
been scrambled?

Thanks,
Rick

In any cellphone, the base unit only transmits the audio from the phone
line, not from the cell phone. The reason you usually hear both ends
is that normal telephone lines are imbalanced enough to reflect
the inbound energy back and you hear that. That is why the car side
of the audio is normally much weaker. If the call is cell-phone to
cell-phone, it is a true one way path and there is much less signal
reflected back (or none, unless a speaker phone is in use). In that
case you will hear only one side. If the call is to a PBX
that has a digital connection to the CO, and the PBX uses digital
phones, you may again only hear one side because this path is
almost perfectly balanced.

I'm sure what you are saying is correct.  But I have had no difficulty using
the generic multipurpose power adapter (part #273-1650) to recharge my Pro-43.
I've really had no choice since none of the local Radio Shack stores have
received the correct charger in stock yet.  So I've been using that with good
success so far.
On a related topic, I just got my extra battery holder I special ordered for
the scanner.  I really think these battery holders are a fine idea; I've seen
them on both the Pro-43 and Pro-37.  It lets me take an extra set of fully
charged batteries along for a lengthy trip like an airshow or something; I
can replace the entire set in about 5 secs. on my Pro-43.

I've just ordered a Bearcat 560 from Damark.  They're selling
reconditioned 560s for $70; too good to pass up for permanent
mounting in my car...

Of course the 560 has some major limitations; a 1 digit display
that 'review's frequencies one digit at a time, and only 16
memory locations.

Does anyone have mods, in particular for increasing the number 
of frequencies that can be stored, or perhaps for a full display?

My recollection is that the 560 is as sensitive in the bands it
covers as my late lamented 760 (stolen and awaiting trial as 
evidence of the theft...), which is to say, quite good.

general?  extra?

1.5. Are there mods for including any of these bands?

2. Can I receive CW?  Are there mods for doing so?

3. Is there another scanner that I should be considering?

4. If/when I get a 2 and/or 10 meter transceiver, will it probably be

   They could be virtually anywhere, depending on a few factors -- is it a
private or public institution?  Are they sworn law enforcement officers?
 
    If it is a private institution, they're probably going to be on a
business freq, perhaps in the low 150s or 460MHz area.
 
   If it is a public institution, they could be on a frequency assigned for
local use, or on a frequency allocated for use by the state.
 
   Many campus police forces are technically given police powers via
deputization with the county sheriff department (many people on my campus
used to joke that the officers were 'rent-a-cops,' & had no jurisdiction
once you stepped off campus.  In reality, they had jurisdiction throughout
the entire county, as some people found out the hard way...), & thus could
possibly be on one of the sheriff department frequencies.
 
   If the college is right in the middle of a city, chances are that the
college PD uses a frequency within a few MHz of the city's frequency, so all
their old radios can use the city PD freq if needed.
 
    Either buy a copy of _Police Call_ & lookup the freq(s) there, or post
the name of the college & perhaps some kindred soul will look it up for you.

   Tim

P.S. Just in case anyone is curious, the University of Michigan has a 5
channel, 800MHz trunked system in use by PD, some maintenance crews,
security (non law-enforcement), & a few other users.  They also have a few
VHF & 460MHz business band allocations.

Also the BC-590XLT (same scanner without 800Mhz coverage)

I will agree that it works..  I am surprised that there is no CTCSS option
on the Uniden MR-8100, which is supposedly a "public-safety" scanner (as in
designed to be installed in public-safety vehicles)

I would also like to see the option in a handheld scanner (ie: BC100/200xlt)

  42.70
  42.50
  42.58

(Monitor America is still my favorite reference; concise, correct,

I had a similar problem with my PRO-43 dying too soon after a charge.
I am using the specified charger. It turned out to be a defective Ni-Cad.

The rest would charge up and carry the radio for an hour or so, to the 
cut-off voltage, and then the 43 would start that infernal beeping.

Even though you have new batteries, check them with a voltmeter AFTER
the radion starts to beep. They each should be 1.15-1.3 volts depending
on your meter.
