i personally have not seen antennas for the handset to incease range
but i have seen them for the base and if not installed properly its
like not having any antenna on the base at all
especially if yours is an older model 1.8 mhz and 47 mhz freqs
you have to open the base unit to attach the 1.8 mhz antenna and if it
touches  anything its not supposed to it kills your range

No, no!  I meant that Bat Wing systems *are* friendly to the *non*user.
(i.e. me)  At least compared to GE....

Here in northwest Arkansas, we live a charmed life.  The Fayetteville
Public Safety Trunked system is a 5-pair Motorola job that is fairly easy
to monitor: the hang time on the repeaters is set long and the FD tones
out apparatus on the old VHF freq. by *simulcasting* the fire fleet!
That means that almost all FD traffic gets repeated on VHF.

Then there is the Ark. SP's statewide system (also a Bat Wing).  Get
this: The control tone NEVER moves and certain freqs always have the same
traffic!  Couldn't be easier.

Speaking of E.F Johnson, I don't think that their system meets APCO specs
for a public safety system.  Something about no emergency button.

Bad news...

    Two days after making the modification on the PRO 37...I noticed that that
when the antenna moved around, I couldn't receive any signals. So I figured I
didn't resolder that small little wire inside, well enough, which ended up
being the case. So...I go to start to take it apart, remove the six screw on the
back and when I open up the battery case, the THING STARTS SMOKING....I was so
pissed...I removed the battery pack ( I had nickel-cadium radio shack batteries
in there)...and the thing stops smoking...I then hook it up to a power supply
and luckily, it still works..however, when I put the battery pack back in for
a second and it started smoking AGAIN..

So now it doesn't work with batteries. I cant figure out why it would do this
but THIS HAPPENED BEFORE WHEN I HAD A PRO 34. The battery pack started causing
the thing to smoke...only after taking that scanner apary MANY times (I 
wrecklessly decided to discover a modification for that scanner myself by
just clipping diodes and resoldering them by process of elimination--which I
was later told that there is no 800 frequency modification for the PRO #$)
And unfortunately, I let it smoke too long, and the radio didn't work at all.

Now hopefully, this has to do with the powersource connections..or something
that is touching something that it shouldn't be touching...I don't know..

DOES ANYBODY HAVE ANY ANSWERS TO WHAT THE PROBLEM MIGHT BE WITH MY SCANNER???

    (Im wonderin if my power supply has anything to do with it...)

That's an interesting viewpoint I've heard at several fire scenes since
Toledo went up to 800...  I'm assuming that you're being sarcastic, but
I have talked to some who think that TFD just moved up to keep
monitors off the air!  I've tried to explain the massive 
benifits of a trunked, computerized system over the old VHF but
that never works.

I'll admit that I sure do miss monitoring like I used to, but if
I were a firefighter I sure would appreciate all the benefits of
the new system (realizing that it is not a "right" to have to have
uncoded, easy to listen to broadcasts for the general public...)

It is also possible that your counter is not getting a strong enough
signal to count reliably.  The typical symptom in these cases it to
display a frequency that is wrong.  Usually lower, but if there is
other noise in the vicinity the frequency could be higher.  Try getting
one of the security guys to key up in close proximity to your counter.

Are there variations in the specifications of 200xlt's ??.
 
In reading this news group I see the 200xlt's avaliable in the States have the 800MHz disabled (easily enabled) and are able to recieve as low as 30MHz.
 
I own a UBC 200xlt brought from Dick Smith (New Zealand/Australian equilivant of Tandy), the 800MHz freqs are avaliable, therefore not disabled BUT the scanning range starts at 66MHz not as low as 30MHz.
 
Does anyone have any idea if it would be possible to mod my unit to give it the bottom freq range ????

I would put a "FOLLOW" or "TRACK" button on the "scanner".

When the FOLLOW button is pressed, the software watches the digital
control information appropriate to the activity on the channel you are
currently monitoring.  You are then switched around along with everyone else
on that channel.

Pressing FOLLOW again would return you to "scan" mode.  You would then be
scanning all freqs in the trunked system till you again find one you wish to
monitor.  You then push the FOLLOW/TRACK button again.

Its been a while since I played with the GE trunking radios, but as I
recall, tones were used because GE did not want to do a digital system
(it requires too much bandwidth) and there were not enough sub-audiable
tones available.  The GE trunking scheme allows a company to divide their
fleet up into groups and sub-groups.  Each group will have a different
combination of group ID tones.  Each individual radio can also be paged.
Since thousands of radios can be on a large trunking system, there needs
to be thousands of tone combinations available.

Ads are one thing, reviews are another. Many of the super wide band gizmos
suffer from the problems associated with designing one small radio that
does everything. Most of the recommendations you read out here on the net
are based on real-world use. You've got to first establish just what it is
you want to listen to and work from there. For instance, if you just want
to walk around listening to police and fire, a good scanner like the PRO-43
might be the best choice. If you like to sit at home and search the VHF/UHF
bands, a PRO-2006 might work best. If you like to go on trips and search
everything, including shortwave, the ICOM R1 (the '2SRA is a ham radio as
well) might be best. But each has its tradeoffs: The '2006 is large, the
'43 has less channels, the ICOMs are widely reported to suffer from
intermod/images, etc. The list goes on and on, and as you read here, the
debate over what's best does too.

what you've stumbled across is the old IPTS mobile telephone channels.  they
are still semi-active out here in my area of california, and they are still
used many places.  so far, i haven't heard any truly private conversations on
them, and they seem to be used mainly by news agencies and the like.  they are
crackable, and the inputs to the channels are somewhere in the 157-158MHz
range.  and no, they have nothing to do with cellular...

Nah!  It's DVP (Digital Voice Protection).  Sounds *just* like static.
A Motorola tech friend of mine says it's only about $100/radio these

Sounds like your battery pack hot lead is shorted to ground somewhere. Check

Does anyone have any info (or actually own one) of the new Bearcat
Scanners?  (Bob Parness, are you reading?)  I'm talking about the

features that other scanners have that the 200XLT was lacking in.  I'd like
for my 200XLT to have some of these new features, like:  Continuous
Coverage, Step Select, Auto Freq Store, VFO Knob.  Anyone want to trade a
slightly used 200XLT for a 2500XLT? ;-)

Here is some information I gleaned from a CEI Ad: (Any errors may be mine or
CEI's)

2500XLT-D
---------
Handheld (profile like the 200XLT)
Continuous Coverage 29-1,300Mhz (less cellular)
400 Channels / 20 Memory Banks
Auto Store
Reception Counter
VFO Knob
Turbo Scan (how fast, I dunno)
Frequency Step Select
(all the other features in the 200XLT seem to be present as well)

CEI Sale Price: $349

8500XLT-D
---------
Same features as the 2500XLT-D, *EXCEPT*:
Base Unit (profile like the 760XLT)
500 Channels
Alpha Numeric Display
Aux Tape Out
Selectable Delay

CEI Sale Price: $369

I'm wondering if they are TRIPLE IF like the PRO-43 or still double like
the older models.  Reviews anyone?
