No, I wouldn't want anyone in my neighborhood building even a small
nuclear device. Nor would I feed too comfortable with a junior chemist
playing with mustard gas or nerve agents. Should it be legal to own
handheld missle launchers like the "stinger". Whattaya think now?

Besides, I was making a general statement of fact, not expressing my
personal opinion. Drugs I don't have a problem with. They should be
legalized... those that kill themselves with drugs are just as stupid
as the guy who puts a loaded gun to his head.

  Chances are you've got your counter set in the wrong frequency range.
 When my Opto 3000 is set in the 200MHz & below range & I key up with a 
25 watt transmitter on 223.500, the counter will lock up on about 100MHz.
 
  Make sure the settings on your counter are optimized for either the 150MHz
area or 460MHz & try it again.

A couple of problems with this:
  (1) It seems like each trunking system uses different signalling technology.
      Thus any scanner would have to be able to handle a bunch of these,
      and would become obsolete quickly. 
  (2) It is illegal to receive digitally encrypted signals. I don't know
      if it is illegal to build decryptors, but if it isn't, it would be
      quickly.
  (3) The digital encryption schemes are quite strong. I doubt that you
      could afford a scanner that could decrypt them (without knowing the
      key beforehand). Such a scanner would probably cost at least
      $20,000,000 (in order to crack the DES code). Now, you are probably
      going to respond "yeah, but they cracked the Videocipher" to which
      I shall pre-emptively respond: "Yes, but that's different."

Supposedly, we don't have secret police in this country. Their policies 
and proceedures are supposed to be subject to the approval of the 
citizens. We shouldn't HAVE to defend ourselves from the police. We do, 
of course, but that's why the quote is in my sig.

Considering how many police I know and work with, this is a surprise to

Some of those other spaces will remove capabilities, if you install a diode.
The same is true if you remove the wrong diode.

The frequencies used depends on the cell - and the sytem. Adjacent cells 
will not have the same frequency, or adjacent frequencies. Since they lay

My understanding of trunked 800MHz communication is that one channel
is used to control all communications on the other channels. It does
not seem too difficult to me to builda scanner with two receiver
sections, one for the control channel and one for the data signals.
All that is needed then is a computer program to decode the control
information and to use that information to follow the desired signal(s)
through its(their) frequency changes. Of course, this is no help if the
signals are encrypted as well, but I don't think too many departments
would bother. I expect the scanner manufacturers to come out with this
type of product as soon as there is a big enough market.

If what you are hearing is from a Motorola 800mhz trunked system, it might
well be a digitally encrypted voice you are hearing.  Properly equipped
radio's (both base and handhelds) are capable of voice digitization with
encryption.  Having had the oppurtunity to play with them myself, the digitzation function is activated by holding down the light button for several seconds(
if memory serves).  A small lock symbol then appears on the LCD display.
Note that the radio can receive digital transmissions even when it is not
set to receive them itself.  If a radio set to receive digital voice receives
a regular analog signal, the little lock symbol flashes as a warning.

Hartford CT recently went with a GE 800 trunked system for all services.
I used to live in that area and listened to their old conventional systems.
As nonuser-unfriendly as the GE system is, I found that with about an
hour of practice I was able to follow most conversations without too much
trouble (although it is still difficult to zero-in on just one particular
agency). The trick is to enter all the channels in the system and start
manually stepping through the channels as soon as someone unkeys the
microphone (don't wait for the beeps), looking to find the reply on
another frequency.  If you're quick and pay attention to the voices,
it's not too tough to follow the conversation.  You may miss the quick
"10-4" reply, but any extended transmission you're bound to find.

Actually, I was quite surprised how much more liberally the radio is
used in Hartford now that they have trunking.  All sorts of information
which used to be passed only by phone now comes over the air.  In addition,
there are usually at least one or two telephone conversations in progress
using the phone interconnect on the system, and these stay on one frequency
for the duration of the call.  It is no longer possible to monitor Hartford
by sitting passively by the scanner and just listening; but for those
willing to put forth the effort with the "hands-on" method, there is
lots to hear.

Supposedly these are still in the prototype stage, not due out until spring

I assume that it is glued on. Getting it off will depend on the

I think many of you are overlooking the obvious.. When trunking systems
become a way of life in your area, and you want to monitor them, do what
we did in this area. Just purchase a piece of equipment that is 
compatible with the system(s) in question, ie: Motorola, GE, Johnson,
Standard etc.. and then you can monitor to your hearts content.. You just
select which fleets, (announce groups), sub-fleets, (talk groups) you
want to listen to and bingo, all of the other junk disappears, and you
hear every message loud and clear.. I agree this is more costly than
a scanner, but it works, where a scanner fails.
