RECOMMENDATIONS FROM OUR READERS
Autumn is here and it's time to cover some letters that have come in
the mailbag. We have some Missouri frequencies, several recommendations
on computer control software and antennas, and we round up with a quick
tutorial on getting type acceptance equipment information from the
Federal Communications Commission (FCC) website.
Green County/Springfield, Missouri
My name is Gary and I am a subscriber from Springfield, Missouri.
Here in the Greene County, Springfield, Missouri area, we are in the
final stages of installation of a new 800 MHz trunking communication
system for all public service agencies. I would like to ascertain if
you have, have heard about, or can obtain any information regarding
this new trunking system. I have the frequencies they are to operate
on, but I don't have any information about groupings etc. Some of the
agencies are simulcasting on the new trunking and the old UHF system.
Any assistance and/or information you have would be appreciated.
Thanks much, Gary.
The Greene County Sheriff's Department historically as used a couple
of frequencies in the VHF band, namely 155.145 and 155.730 MHz.
The Springfield Police Department has several frequencies in VHF and UHF:
154.860, 154.890, 154.490, 458.800, 458.850, 460.020, 460.100, 460.225,
465.400, 465.500, 465.025, 465.100 and 465.225 MHz. The Springfield
Fire Department uses 458.250, 458.600, 458.950 and 458.6250 MHz.
It's not clear how long these frequencies will remain in use, since
the new trunked radio system is currently being brought on-line for
the county sheriff and highway department as well as the Springfield
police, fire and public works. Another seven agencies and a dozen fire
departments are expected to join the system in the near future.
The new Motorola Type II system is configured to support both analog
and digital radios, with the majority of traffic expected to be analog.
Officials claim that digital communications will also be encrypted.
The initial radio fleet includes about 120 digital radios and more than
1,600 analog units.
Seven sites will simulcast on eighteen assigned frequencies: 854.9875,
855.4625, 855.7375, 856.2125, 856.4375, 856.7125, 856.9625, 857.2125,
857.4375, 857.7125, 857.9625, 858.2125, 858.4375, 858.7125, 858.9625,
859.2125, 859.4375 and 859.7125 MHz.

Comments on Computer Control
First, a positive report about BlackBag's control programs for Uniden's
780XLT base/mobile scanner and the 245XLT handheld.
I wanted to take a few moments to tell you that your
June article in
Monitoring Times encouraged me to go out and find a PC control program
for my Uniden BC780XLT scanner. I have owned this fine scanner for
several months, and had considered getting a control program for it.
Your article spurred me on.
After going to the StrongSignals web site to check out what my options
were, I decided on the program from BlackBag Software. I don't know if
this is an indication of the overall quality of the company, but I placed
my order via their website on Saturday morning, and my order arrived at
my house the very next Monday afternoon. Talk about service!
I purchased two software control programs from BlackBag. The 780 control
program and the BC245XLT control program. I should note that the 780
control program I purchased was less than half the cost of some of the
major programs on the market today, and it even comes with a control
cable include in the price. The software loaded right up without any
problems, and runs quite well on my Windows XP Pro system, so I presume it
will work equally well with earlier versions of Windows, including Windows
2000. I was able to get the program configured in a matter of minutes,
and was doing Service Searches and Trunk tracking almost immediately. The
user interface is clean and functional and very intuitive.
Also, for the same price of $28.50 ($25 + $3.50 for priority mail),
I got BlackBag's Frequency Logger program, which is a nice addition to
operating my 780.
If there is a weak point in the package that I bought, it is that no
documentation comes with the program. You are prompted to take action
through pop-up dialogue boxes, but I can't find a documentation file
on the CD or on the company's website. Also, there does not seem to be
any help available through the program. Maybe I've missed something,
but I've looked several times without success. Though using the program
was easy for me, it might not be as easy for someone who is still fairly
new to working with Windows.
The website address I went to, to get this program was http://www.bc780xlt.net/.
They also carry a Palm OS control version of the program.
That's it. I just wanted to let you know that this program is well worth
the money for anyone looking for a good, fairly priced for what you get,
control program for their BC780XLT.

Also in the mailbag, some positive words about ScanCat Gold SE control
software for several radios.
I just read your column in the
August 2002 issue of MT and thought I
throw my two cents in.
I've had computer controlled radios and software for sometime now,
beginning with the Icom PCR1000 and leading up to the 780XLT. I own the
PRO-2052, the 245XLT, the 895 as well as computer-capable amateur gear
such as my Icom 706, Kenwood D700A and now my Yaesu VX-7R. I mention
all that to reinforce the point of the need to have a computer control
program capable of controlling many different types of radios - receivers
and transceivers alike. That program is Computer Aided Technology's
Scancat Gold SE.
Obviously, the multi-radio capabilities are its number one asset, but
with the program's ability to use several different database formats,
the logging choices and its trunk tracking ability make the software
even more alluring. I can download a database from the several frequency
CD-ROMs I own into a DBase format and scan that database with Scancat
without any further manipulation required. I can do complete logging
of these frequencies not to mention graphical plots of frequency hits
vs. time or decibel - there are several possibilities. The software
also has a built in spectrum analyzer which works well with all the
radios I've controlled with the software. Heck, the software even has
a subprogram for changing, copying and editing a wide range of files
and databases including it's own SCN and FRQ formats.
I think anyone who has invested in a computer controllable receiver has
the right to expect the best in control software especially if there
are large databases to be shifted through or a lot of programming.
For my money, ScanCat can not be beat.
That's my two cents worth. I look forward to reading your column in the
future. Till then, 73.

I have also received a number of comments regarding various antennas
that people are using. Here Brian makes some good points and offers
In reference your column in the July MT, I have the following comments.
Firstly you have to differentiate between base and handheld units.
For base stations you can use a rotatable antenna like the Grove Scanner
Beam, with good quality coax as a must. In my case I have good success
with the Grove Scantenna mounted in my attic.
For handhelds it's a different story. I think it was Bob Grove who said,
"You don't need antennas but attenuators." In a lot of cases putting a
good antenna on your scanner creates more problems (front-end overload,
cross modulation, etc.). I agree that the "rubber duckies" leave a lot to
be desired. Personally I use a Watson W-889, but there are similar units
available such as the Grove Universal Telescoping Whip and the MFJ 1812.
Also good are the MFJ 1710 or the AEA Hot Rod, which you can also use
for transmitting on 2 meters.
Thanks, Brian in Seabrook, Texas
Another reader has found a good 800 MHz performer for handhelds.
I agree the Max antennas are great for 800 MHz but are a little
difficult to live with on a handheld strapped to your belt. I found a
very effective 800 MHz "ducky" on the web at Durham Radio in Canada. I'm
very impressed with the reception that their "800 BNC" gives me on our
countywide 800 MHz trunked and non-trunked towers. It even performs
very well inside the car.

Uniden Bearcat 785D
In August the Federal Communications Commission (FCC) granted type
acceptance to the soon-to-be-released Uniden BC785D, the mobile/base
version of their APCO Project 25 scanner.
The FCC's Office of Engineering and Technology (OET) maintains an
"FCC ID Number Search" on their website that allows anyone to look up
filing information related to a certified or type accepted product.
Every FCC identification number, usually found on the back or bottom of
a piece of equipment, is made up of two parts. The first part is the
Grantee Code, which is made up of three characters assigned by
the FCC to a company to identify all of their products. The remainder
of the ID number, anywhere from one to 14 characters, is called an
Equipment Product Code and is assigned by the company submitting
The 785D has an FCC ID Number of AMWUB316,
where AMW is the Grantee Code and UB316 is the Equipment Product Code. We can
use this information on the FCC's website to find the filing information
Uniden submitted related to this receiver.
Using your favorite web browser go to http://www.fcc.gov/oet/fccid/ and you should see the search
form. Put in AMW in the Grantee Code
box and UB316 in the Equipment Product
Code box, then click on the "Start Search" box.
You should get back six records of information. Click on the first
icon under "Display Exhibits" and you'll get a dozen records that Uniden
You can then click on any icon in the "View Attachment" column. The third
selection, for instance, brings up a picture of the rear view of the
receiver, showing the connectors and the probable slot for the digital
You can look up information on nearly any piece of approved equipment.
The FCC ID for the PRO-92 scanner, now on sale at Radio Shack for less
than $200, is AAO2000522. My Radio Shack
wireless thermometer is AAO6301026R.
I've even looked up the filing records for the SpeedPass receivers you
see at many of the Mobil gas stations.
That's all for this month. Enjoy the fading days of autumn, if you
can, and let me know what you're monitoring via electronic mail at
