The purpose of this article is to explain how to use a scanner and radio
receiver to eavesdrop on private calls from homes, offices, cars, ships,
aircraft, and trains. I will discusses the best methods of monitoring, the
equipment needed, and list the necessary frequencies.
Why scan?
---------
It is quite a simple, and in most cases LEGAL, to listen-in on cellular,
cordless, ship/shore, air/ground, pagers, etc. The benefits of such
monitoring, aside from entertainment, can be quite high to the discerning
listener. Callers quite often route to their favorite LD carrier to place long
distance calls. They call their voice mail systems, private company
lines and diverters. If you are have a specific interest in an individual or
company you may peek in on their "private" conversations, learn who they are
calling and what they are up to. Apart from radio-telephone communication
scanner hobbyists are entertained by whatever they overhear on their radios.
Police cars, fire engines, ambulances, armored cars, trains, taxis, airplanes,
and buses are all equipped with radios and you can listen in on them. You can
monitor the local police and fire departments to hear about events before the
news reporters screw them up. Hostage dramas, bank robberies, car crashes,
chemical spills, tornado sightings are all there.You can hear a high speed
police chase, Secret Service agents on a sting operation, and undercover FBI
agents as they stake out a suspect. How about listening to a presidential
candidate discuss strategy with his adviser from a 415 MHz radiophone in Air
Force 1, or a team of G-men protect him while transmitting in the 167 MHz
range? Listen to your neighbors deal drugs over their cordless telephone, or
as their conversations are picked up and transmitted over the airwaves by their
sensitive baby monitor intercom. It's all there in the 46 and 49 MHz ranges.
What Equipment is needed?
-------------------------
Scanners are available in two varieties: crystal controlled and
programmable. The crystal controlled models are cheaper, but require the user
purchase and install a $5 crystal for EACH frequency of interest. Programmable
(synthesized) units don't require crystals and usually have a keypad that
permits you to store frequencies into channels. Programmables are now so cheap
it doesn't make sense to buy a crystal unit as your main scanner unless you get
it for under $45 or so. You can get a battery operated hand held scanner, a
bigger "base" scanner which is powered from an AC outlet, or a mobile scanner
which connects to your auto's electrical system.
Make sure your first scanner:
1. Has a "search" feature, which allows it to search all the frequencies
between two frequency limits of your choosing. The lowest cost
programmables can't search.
2. covers the 800 MHz band, which is where cellular-telephone is broadcast.
3. Has an AC-adaptor available, as scanners eat batteries.
4. Has an earphone jack as you may want to record your findings.
If you're not sure whether you'll like scanning, don't want to spend much
money, a 16 channel radio will do. In general, the more channels and banks,
the better. Deluxe scanners can be controlled by a personal computer, although
this feature isn't important to most scanner owners.
Currently, the more popular scanners include the Uniden/Bearcat 760XLT
(a/k/a 950XLT) and Radio Shack PRO-2022 and PRO-2006 base/mobiles, and the
Uniden/Bearcat 200XLT (a/k/a 205XLT) and Radio Shack PRO-37 portables.
All scanners come with a built in antenna, permitting reception up to
about 20 miles or so. Outdoor antennas can extend reliable reception to 100
miles or more.
A breakdown of exactly what there is to listen to out there:
Cordless phones:
----------------
It seems like everyone has a cordless phone now days. Cordless phones are
quite easy to monitor. Cordless phones are duplex, they transmit sound from
the handset to the base, and the base transmits both callers voices back to the
handset. Obviously this is the frequency you want to listen in on. Cordless
phones are broken into ten channels. They are as follows:
Channel Frequency (in MHz)
----------------------------
1 46.610
2 46.630
3 46.670
4 46.710
5 46.730
6 46.770
7 46.830
8 46.870
9 46.930
10 46.970
Most cordless phones have the channel number stuck on the back of the handset,
and some have multiple channels. The easiest thing to do is simply scan the
whole list of ten. The main problem with cordless phones is the range. They
are seldom able to broadcast further than a block or so away. If you want to
monitor a users phone calls, the best method is to hook up a Voice-Actuated
Cassette recorder to a handheld scanner, wrap the whole combo in a ziplock bag
and lay it in their shrubs. Come back the next day and you have a complete
record of all calls made and received on their cordless. With the use of a
touch-tone decoder you can even determine who they have been calling!
Cellular Telephone:
-------------------
Cellular telephones are quite useful sources of information. Doctors,
lawyers, the phone company and business officials all regularly use celluar
phones. LD cellular calls can be quite expensive to say the least, so most
users prefer to use Sprint, AT&T, etc. as their long distance carrier. Thus
you can quite often hear them giving out their calling card number to the
operator.
Here is a method of determining which frequencies are used in a cellular
system, and which ones are in what cells. If the system uses OMNICELLS, as
most do, you can readily find all the channels in a cell if you know just one
of them, using tables constructed with the instructions below.
Cellular frequencies are assigned by channel number, and for all channel
numbers, in both wireline and non-wireline systems, the formula is:
Transmit Frequency = (channel number x .030 MHz) + 870 MHz
Receive Frequency = (channel number x .030 Mhz) + 825 Mhz
"Band A" (one of the two blocks) uses channels 1 - 333. To construct a
table showing frequency by cells, use channel 333 as the top left corner of a
table. The next entry to the right of channel 333 is 332, the next is 331,
etc., down to channel 313. Enter channel 312 underneath 333, 311 under 332,
etc. Each channel across the top row is the first channel in each CELL of the
system; each channel DOWN from the column from the the first channel is the
next frequency assigned to that cell. You may have noted that each channel
down is 21 channels lower in number. Usually the data channel used is the
highest numbered channel in a cell.
"Band B" uses channels from 334 to 666. Construct your table in a similar
way, with channel 334 in the upper left corner, 335 the next entry to the
right. The data channel should be the lowest numbered channel in each cell
this time.
You want to tune-in on the non-data, RECEIVE channels. The transmit
channel is a low power signal from the mobile source to the microwave tower,
which rebroadcasts both caller's voices. The Data channel is used to send such
things as the callers serial number, and connecting cell information, this
information is not audible, though I hope to discuss this in depth with a later
article.
Scan from around 870 MHz to 894 MHz and note any signals you receive.
Once you find a frequency listed in the following chart, you know that your
area also uses all other channels in that cell for that particular band.

Restoring cellular reception.
Some scanners have been blocked from receiving the cellular band. This
can be corrected. It started out with the Realistic PRO-2004 and the PRO-34,
and went to the PRO-2005. To restore cellular for the 2004, open the radio
and turn it upside down. Carefully remove the cover. Clip one leg of D-513 to
restore cellular frequencies. For the PRO-2005, the procedure is the same,
except you clip one leg of D-502 to restore cellular reception. On the PRO-34
and PRO-37, Cut D11 to add 824-851 and 869-896 MHz bands with 30 kHz spacing
All these are described in great detail in the "Scanner Modification
Handbook" volumes I. and II. by Bill Cheek, both available from Communications
Electronics Inc. (313) 996-8888. They run about $18 apiece.
Pagers:
-------
Pocket pagers and the like operate in the area of 150-160 MHz.
Phone-Patches:
--------------
A phone patch is a way to use a telephone via two-way radio. Basically how
it works is the patch is connected to a repeater and a phone. The patch will
interpret signals from a transceiver to activate itself and call out to the
desired party. This then allows the person with the transceiver to call anyone
from his handheld radio unit. Phone-Patches are usually located on most bands,
as they are simply an attachment to the repeater.
Police, Fire, Ambulance and the like:
-------------------------------------
The easiest way to find these frequencies is to go to Radio Shack and buy
their listing, it runs around $8, and is set up for groups of neighboring
states. Hell, photocopy the pages you want and then return it! But generally
these are located in 450-460 MHz.
Typical Band Usage:
-------------------
The FCC dictates who uses what bands for radio broadcast. Following is a
breakdown of the general distribution of FCC licensing. These are by NO means
set in stone, there are always exceptions.

800 MHz:
Unlike lower bands, the 800 MHz band is allocated on a first-come first-serve
basis. There are two categories for licensing: Public Safety and Industrial.
Sytemsusing one to five channels are conventional. Five channel systems might
use trunking, but all systems with more than five channels must use trunking.
