TAP No. 47 - Radar Detectors, CB Info

Reprints a news feature on the booming radar-detector market (the ‘Fuzzbuster’ and similar devices), covering their patchwork legality across states, the ongoing arms race between detector makers and police radar, and commentary from Fuzzbuster inventor Dale Smith framing the devices as a check on a ‘police state.’

“Depravo" mentioned the use of single frequency (SF) tones

LETTERS FROM READERS
Dear TAP,
Hopefully, devices such as this one and others even more advanced
will help to close the technology gap again in the never-ending battle
with these "blue-belled" fuckers.
It is a matter of increasing concern the growing number of
felony convictions which are being passed on to really "regular"
folks these days. Such truly trivial items such as mere possession
of an encoding device, blasting caps, night viewing equipment, and on
and on... they might as well lock everyone up and get it over with!
‘The dirty fuckers and their "Grand" juries are causing thousands
to lose their rights to possess guns, vote, they are not even allowed
to associate with other "felons".
Did you know that simply selling
three rifles within a 90 day period is a federal felony rap? 1 have
heard of individuals who were “out of favor" with the government be
approached by Alcohol and Tax agents posing as interested gun buyers
and having made the required minimum "purchase" then busted the poor
and unsuspecting victim. This has happened to those with leanings
both left and right - it looks as if Nixon-menia is still with us!
Such a legacy as this should make us all aware that after all, 1984
isn't really all that far away now.
As a former design engineer for the Bell System, am in a position
to know how really fucked up their attitude toward the public they
"serve" really is. Publications such as TAP mst be supported and
not allowed to go under. Not all of us are into the circuitry end of
things - how about those of you who really make the system talk?
Lists of country codes and foreign senders should be updated yearly,
the system is in a state of constant flux. The U. N. Bookstore in
New York will sell copies of the ITT Green
Book. Get the volume on
“Signalling and Switching" to be brought up to date. Ever wonder
what those strange tones are when you place foreign calls? This
book will tell you!
Inquiries regarding these circuits may be made by the placing
of an ad in the “personal” column of the Seattle Post Intelligencer.
Mention my name, leave telephone number or address.
Gentlemen, keep up the good work. There is more at stake in this
than you may suspect.
Milo Fonebill
Your past couple newletters have indicated an urgent need for
new material - well, let me lay one on you! Here enclosed are plans
for two different units, one a combination blue/red, and the other
red only. They are fully automatic, and programmable.
Liberal use of COSMOS integrated circuit techniques precludes
even the need for an off/on switch, since the standby power on these
is for all practical purposes, 0. ‘These are usually built in layers,
and it results in a very vloume efficient device (sec illustration
of hand-held unit). ‘Three layers consist of front panel with keyboard,
memory and logic board, and tone oscillator/amplifier. It is my |
feeling that the construction of an advanced unit of this type is
best managed by individuals with a fair amount of electronic experience.
For this reason, no effort was made to include pin numbers, exact
layout instructions, etc. It is felt that the procurement of RCA's
COSMOS Handbook or its equivalent should be made prior to planning
or constructing your own unit, and all details may be found there.
In actual operation, the blue/red unit is very simple and straight-
forward. One need only key in the entire evening's "activities" prior
to leaving for a booth (you wouldn't use your own, would you?). The
actual number of telephone numbers which can be stored and sequenced
through are dependant on many factors; however, a total of 64 key-
strokes are possible. Foreign sender codes, area codes, local numbers
may be mixed in any suitable order.
In examining the schematic, you
will see that the memory will shift each new MF combination out with
every clock pulse, thus enabling the proper oscillator combination,
Detection is made of KP or KP2, which when sensed, halts the sequence,
waiting for another push of the "run" button to continue. Numbers
are re-circulated, and may be recalled by sequencing through the stored
combinations.
The tone pair bursts are 50 ms in duration with 50
of silence in-between. KP and KP2 are 100 as in agreement with ITT
specification.
T£ you have experienced difficulty in penetrating exchanges
which are employing the new "Message Format Discriminators", you will
really love using this - the calls sail through every time, while the
manual units faill The feature which is most appealing to those of us
who are using these is the fact that the units are very compact and
easily concealed, pre-programmed so that there is no need for hauling
a big "box" out in public view cach time you "dial". Although both
units in the illustrations contain built-in speakers, there is also
Provision for remote jacks, so that a tiny speaker or headphone unit
may be easily palmed. With this unit, it was a simple matter to place
a call to Moscow, using the central desk of the BIT without raising

the bank to pay the bills and rent on their hole
in the wall! If you think us writers and workers
here are getting payed, you're full of shit!
I'm waiting for the word on whether to write
this column or not, but figured I'd write it up
any way just in case.
I was supposed to give a modification for
CBs using the type of synthesizer explained in
my last column, but while thinking about it, I
figured out an easier way to do the entire syntha
series, that is if there is still something to
write it fort???
-
The mod, will come after all the synthas are
looked at. So, this second type of synthesizer is
used in 23 channel radios manufactured by Sharp,
fTeaberry, Courier, Pearce Simpson, and probably
others.
Again there are six main crystals used in
oth the transmit and receive modes. They happen
to be, 23.290IiHz used for channels 1-4, 23, 340MH2
used for channels 5-8, 23.390!Hz for channels9-12,
23.440lHz for channels 13-16, 23.490IHz for channels
17-20, and 23. 540ilHz for channels 21-23.
Tn these radios there are.another four crystals
that are used in both modes,:+ Channels 1,5,9,13,17)
and 21 use the 14,950MHz crystal - Channels 2,6,10,
14,18,and 22 use the 14,960lHz crystal - Channels
3,7,11,15, and 19 use the 14,970liHz crystal - and
channels 4,8,12,16,20, and 23 use the 14,990IHa
crystal.
.
When -the radio is in the tranamit mode on,
say channel five, the 23, 340tlHz and 14,950MHz
erystals are added in the synthesizer mixer to
produce a 38.290ilHz output. Wext the ist IF
frequency of 11,275iii2 is subtracted from the above
38,290:Hz to give a frequency of 27.015liHz, channel
five. The procedure continues all the way from
1 through 23.
*.
The receive mode works the same way, even
though a 11.730Miz ‘crystal is thrown in somewhere.
This has to do with heterodyning in order to
produce the 455kHz 2nd IF frequency, but don't
worry about it. Just remember, in order to check
your receiver's frequencies the frequency of the
1st local oscillator equals the sum of both main
crystals ( the two crystals that are used for one
channel in both modes ) plus 11.275IfHz.
But forget
it, since this-is all constant and in doing mod-
igications they always stay the same. ‘hewl!tt!
ven though all this chit is probably boring
to read, Hon't sweat it. I've got some goodies
planned for future issues (I hopel!!!?) of TAP.
If any of you out there would like info on
any type of CBs or equipment just drop me a card
along with a long stamped self-addressed envelope,
and I'd be glad to send you back manufacturer's
pamphlets or whatever.
Member, send any info, questions, comments,
money, requests for info, money tor

be a bastard and pull
a cliff
hanger on ya by telling ya that
in our next issue, we'll tell
ya
where ya can LEGALLY by a Blue Box! How's THAT fer balls?!
I couldn't end the year without thanking Stan & Duff fer making
this one of the most expensive but far fuckin out summers that
T've ever had! Thankx again, ya burn-outs!
