Introduction
THERE ARE 2 BOOKS IN THIS EDITION SET. AN ORDER FORM FOR THE
OTHERBOOKISAVAILABLEINTHEBACKOFTHISBOOK.
The newest versions of RADIO/TECH MODIFICATIONS is Edition 7, part
A (7A) Edition 7, part B (7B). Edition 7A contains all known
modifications for ICOM and Kenwood Radios and mods for the popular
scanners. Edition 7B has all the modifications for Yeasu, Alinco,
Standard, Azden, KDK, Ten Tee, Ranger, Uniden, Radio Shack and popular
CB radios.
During the past 5 years we have created 7 Editions of Radio/Tech
modifications. Each new edition included the information contained in
the previous editions. So if you have the current edition, you do not
need to purchase the previous ones.
We make every effort to improve the illustrations with each new
edition. The modifications presented here have been performed by
many people through out the world. Unless the manufacture changes
the radio in some significant way, the modifications contained in this
book are accurate and current.
We make every effort to provide all available modifications for every
radio we can find. In some cases, additional information is available for
a radio that can not be presented in the book. We try and keep this
informations on file and will provide it to verifies owners of the current
edition for a small fee. We also try to keep the cost of the modification
books as low as possible. We ask that you do not photocopy pages from
these books. We will support you however we can, however, if you call
us we will ask that you have the book in your hands at the time of the
call.
It was only logical that we start to include the alignment points for each
of the radios. Since you are inside them performing the modification, it
is a good time to adjust the Modulation and Power levels.
If you find a new radio is not listed in these pages, contact us and ask
about it. We may have a copy that did not make the printing deadline.
If you purchased the book and have proof of purchase, we can make the
1
Introduction
new modification available to you.
Your comments and suggestions are always welcome. If the. mod works
great, let us know. If you can't make the mod work, let us know. We
can't test every modification, we don't have all the radios. Your help
will make the next volumes better for everyone.
A word on the Radio Shack HTX-202
Once in a while we receive a modification for a radio that we are unable
to test. If we receive verification that a modification works from a
number of people, we will print the -modification in our new edition.
We have only had one problem with this policy, the HTX-202. We
received copies of a modification from three different people. One
person in particular wrote u·s and we called him back about the mod.
He swore that he had done the modification to three radios and it
worked perfectly.
Very soon after publication we started to get calls from everyone who
tried to perform the modification. No one could find the part specified.
It turned out the parts did not exist. Apparently the modification was a
hoax created by someone as a joke and published on electronic bulletin
boards. (The fellow no longer answers his phone!!!)
After researching the radio, finding the original manufacture (no it not
ICOM) and reviewing the radio schematics, it has been determined that
there is no modification available for the HTX-202.
We think that Radio Shack requested a radio that could not be modified
from the manufacture, to protect itself from FCC problems. If you
purchased one of these radios, write a letter the Radio Shack and
express your personal dissatisfaction. If they get enough letters and
complaints they may think twice before limiting their products in the
future.
Good luck and remember to use common sence before you press the
Push-To-Talk button.

Introduction
Cellular Phone Bands
The Federal Communications Commission (FCC) is the agency in charge
of controlling the airwaves in the United States. It has been their
responsibility to oversee the content of the transmissions from
broadcasters in the United States.
On April 26, 1993, the FCC has decided that they should not only control
what information is broadcasted on the airwaves, they should also
control the sale of radios capable of receiving certain frequencies.
The issue in this decision is protecting the privacy of cellular phone
users. The Cellular phone frequency band in the upper 800 MHz range
has become a favorite scanner listening band. The cellular users
deserve their privacy. Hence, the FCC has declared a ban on all scanner
style radios or converters capable of receiving the cellular band.
The wording of the new law is intended to regulate what type of
receivers may be sold in the United States.
Section 15.121 Scanning receivers and frequency converters
designed or marketed for use with scanning receivers.
(a) Except as provided in paragraph (b), scanning receivers, and
frequencies converters designed or marketed for use with scanning receivers,
must be incapable of operating (tuning),' or readily being altered by the user to
operate, within the frequency bands allocated to the domestic Public Cellular
Radio Telecommunications Service in part 22 of this chapter (cellular telephone
bands). Receivers capable of "readily being altered by the user: include, but are
not limited to, those for which the ability to receive transmissions in the cellular
telephone bands can be added by clipping the leads of, or installing, a simple
component such as a diode, resistor and/or jumper wire; replacing a plug-in
a
semiconductor chip; or programming semiconductor chip using special access
codes or an external device, such as a personal computer. Scanning receivers,
and frequencies converters designed or marketed for use with scanning
receivers, must also be incapable of converting digital cellular transmissions to
analog voice audio.
(b) Scanning receivers, and frequency converters designed or marketed
for use with scanning receivers, that are manufactured exclusively for, and
marketed exclusively to, entities described in 18 U.S.C. Section 2512 (2) are not
subject to the requirements of paragraph (a).
