UHF Mobile Phone Technology and You

UHF MOBILE PHONE TECHNOLOGY AND YOU



ME, YOU, AND THE REPEATER
~~~~~~~~~~~~~~~~~~~~~~~~~
  What you will be accessing is the repeaters in your local area.  Most large
cities have at very least 5, and some have upwards of 15.  Now each repeater
usually is accessable throughout the city, although they get better reception
in certain areas.  Soo, once you estabish the region that works best for you,
that will be the target repeater.  Now, when you dial the repeater, you will
get another tone, much like a PBX, where you are supposed to enter the extension
of the mobile phone you wish to reach.  Remember that each repeater is
independant, so you will need to program yourself on all the ones you wish to
use.  Also, choose one as your base channel, usually the one that is in the
region you will be around the most, and program this one for ringing capab-
ilities.  One of the real benifits of this is you can set up multiple extentions
on each repeater, and have tons of phone numbers and extensions.
  You can also access the voice paging feature, and capture a voice mail box.
This is accomplished by simply assigning yourself a 5-tone pager id, and then
finding the phone number of the VMB that corresponds to it.  This is especially
nice when you don't necessarily want people to realize where you are, or when
you want to call screen losers.


HACKING THE ZETRON
~~~~~~~~~~~~~~~~~~
  Here's the big joke of this... The 'hacking' process.  The admin extension
is usually 7 digits, and usually starts with 000.  Now that's still quite a
few possibilities, right?  Nope, the shitty designers of this system made it
so when you enter a incorrect number it gives you that wrong tone.  So say
the password is 0004311, when you call up, you enter 0, no tone?  Enter 0 again.
Still no tone?  Enter 0 a third time.  No tone again.  Now enter 0 a fourth
time.  Ding-dong... Wrong tone.  Now just repeat the first three, and try 1
for the fourth, and so on.  Basic.  And once you're in, there are no other
passwords... Boy these people sure are security concious.


THE SUPREME MENU
~~~~~~~~~~~~~~~~
  Here's a 'flow-chart' of the menu structure for most Zetron-series repeaters.
I include the main and sub-menus, and also all the possible selections for each
command.  Now remember, the system is hot-key, and you can type '!' anywhere
in it to get back to the main menu.  It's formatted a little past 80 columns
since it is more useful printed and I wanted it even-looking.  Here we go...

** End of list **


IMPORTANT COMMANDS TO KNOW
~~~~~~~~~~~~~~~~~~~~~~~~~~

  Ok, Now I'll discuss some of the more necessary commands, and what they do.
Most of the others are pretty easy to figure out, or are not necessary.  The
only really useful area is in the TOLL RESTRICT, TELCO CONTROL, and menus.
  The system is usually split into two different systems, although on MOST they
only use one of them.  So, what you want to do is configure the [2] settings
for you, and leave the [1] settings untouched (so they are not aware of the
usage.
  You will want to change the following in the TOLL RESTRICT menu:

                4. Max toll digits 2 = 20               (Amount of numbers)
                5. 1st digit restrict 2 (chrs) =        (Non-allowed first digit)
                6. 2nd digit restrict 2 (chrs) =        (Non-allowed second digit)

    This will allow you to call oversears or special numbers with no hassle.
    Next in the TELCO CONTROL menu:

                2. Call limit timer-2 (*min) = 99       (The Maximum call time)
                4. Channel ringouts-2 = 9               (Number of rings before
                                                         giving up)

    This will configure your phone to allow 99 minutes per call, and let you
    ring someone nine times.
  Make sure not to edit anything within the STATION ID menu, since this will
bring the FCC down on the operators head, and we don't want the repeater to
get shut down.
  Also, if you were wondering what they do if they find out that you're in the
system, well, that's easy.  They disable the phone modem and enable the packet
one, so only people with HAM setups are able to call up and alter information.
This is a little extreme, but most of the time it will happen if you're billing
an enormous amount of calls to it, or taking up a massive amount of airtime
(and neglecting to cover it up).


VIEWING USER INFORMATION
~~~~~~~~~~~~~~~~~~~~~~~~
  This is one of the nicer and more useful functions of the system, this way
you can get a complete listing of all the repeater users, and what services
they have available.
  Here's a list of the most common (and most important abbreviations used in
the user list...

    A = Privacy           B = User enabled        C = * to Answer
    D = # to disconnect   E = DTMF thru           F = Number of ringouts mode
    K = Call timer mode   P = Mobile-to-phone     Q = Phone-to-mobile
            R = Mobile-to-Mobile        U = Toll mode

  PRIVACY means whenever you speak, the repeater will transmit a beeping sound,
so anyone listening will only be able to hear the person you call.  USER ENABLED
is self explanitory, * TO ANSWER means you will only need to dial '*' to answer
calls, instead of '*' plus your ANI.  # to disconnect is the same an answer, but
to cancel a call.  DTMF thru means the repeater will allow DTMF tones to be
transmitted.  NUMBER OF RINGOUTS MODE is which phone callout mode you have (set
this to [2], your custom callout setting).  P,Q,and R all pretty much are the
same, allowing users to call from on to the other.  TOLL MODE is another you
set to [2], altering from the default toll settings.
  Ok, and now here's what the user printout looks like.  USR is the actual user
number, the letters A-X correspond to the above list, ANI is the extension
number, RX is the recieve tone, TX is the transmit tone, TYPE is the type of
paging service, and PAGE is their 5 tone sub-audible...

** End of list **

  The ANI is what people calling you need to dial (i.e. your extension), and
the number you need to dial in order to make calls out.  The best way to use
this is to just piggy-back someones existing account.  They definantly won't
complain when they get all the wonderful features, and then that also leaves
a very obvious (and innocent) scapegoat... My favorite kind.
  The tone userlist is a little different than the mobile users...  This is
mainly for pagers that happen to be using the same repeater, although that is
highly uncommon.  Here it is...

  There has never been any configured on any of the systems I've been on, so
I can't really tell you too much about the configuration information, although
that would lead me to believe that the feature isn't very exciting.


THE CALLER LOG... THE ENEMY
~~~~~~~~~~~~~~~~~~~~~~~~~~~
  Unfortunantly, as with everything in life, there's always a snag... The
caller log, although in this case it just takes a little extra effort to trick
the ever present enemy.  Every space means there were some accounts inbetween
the used accounts that are deactivated.  Here's what the log looks like...

        CALLER LOG FOR xxx-xxxx (xxxxxxxxx)

  On the surface this may appear to be fairly useless, but there is something
to be feared here.  Many of the companies take it upon themselves to total the
time used, and then divide by the number of accesses.  Now what this tells them
is the average call length... And if you're making 45 minute calls, this is
going to boost the call time just a LITTLE past 3 minutes, then all they do is
the same thing on a user by user basis and wala, they know whose account you're
on.
  It only takes a little bit of extra effort to cancel this out though.  Just
place a shitload of small calls, like 10 secs, and one of those for every 2 or
3 minutes you've used on your long call.  This safely masks your using of the
system, as long as you aren't calling Alliance or making LD calls.
  It is true that you can zero this list in the accounting menu, and that's
another way you can get around it, although this alerts them as to there is
either someone else on the system (and they're trying to hid something), or that
there is some sort of problem with the system, and they either try to fix what
is not wrong, or give up and write off the problem (and this is what you hope).
  For those who wish to have all the reference, here's the Tone Dispatch Log...

FREQUENCIES
~~~~~~~~~~~
  Here's the technical description of the frequencies they use:

                405-425, 440-460, 450-470 (in 12.5kHz steps)

  Now since this even though this isn't dual-synchronis, is does use two
freqencies per channel.  Now, is the first frequency was 405.000kHz, the sister
frequency would be 405.900kHz.  Pretty basic, eh?  The second frequency (your
transmit one) is always 0.900 kHz above the recieve.  Usually you can call up
your local mobile phone company and find out their repeater frequencies... Hell,
several have faxed me complete listings and their effective range, I sure do
love companies with great customer service!
  The tones which are used by the repeaters (both audible and subaudible) are
FCC regulated, so they are a standard... Meaning the repeaters tone 13 will
be the same as the Yaesu's tone 13.  For more information on the tones, simply
go to your local library and see what the government has regulated for your
area.


CAN YOU SAY... YAESU?
~~~~~~~~~~~~~~~~~~~~~
  Now there are many different manufactures of UHF phones out there, but the
one I would recommend over Motorola and Maxon would be Yaesu.  They started
out as a pro equiptment dealer only, selling some of the best HAM radio gear
around, then about 2 years ago they entered into the commercial market.  Now
they heave several handheld units available, but I would recommend above all
the others the FTH-7008.  It sells for around $500 (but who's paying? (Refer to
Carding, My Way series)), and has a Priority Channel, Scan, Hi/Lo Power settings,
Auto-Squelch, and 15 channels (not crystals, but synthesis).  Now, you will also
need the FTT-4DT (make SURE it's the 4DT not just the 4, because otherwise it
won't work).  Now the FTT-4DT is a DTMF pad which goes on the unit between the
battery and the body, you can easily do the instilation yourself, and the unit
runs around $280.
  Now what this gives you above and beyond the keypad is a squelch which will
only turn off when it recieves a certain 2-tone combination or a 5-tone sub-
audible.  These are used to make the unit either ring for an incoming call, or
to respond when a page comes through.
  Now here's the beauty of Yaesu.  Your dealer can AND WILL sell you the
software and hardware necessary to program it yourself.  It runs around $80
and is for the IBM XT or better.  This drives the FCC CRAZY and gives you TOTAL
power... Now all you need to do is hack into the repeater and wala... Phone
service.


USES AND ABUSES
~~~~~~~~~~~~~~~
  Now here's the payoff... Not only can you make calls out, long distance or
otherwise, and not have to worry about being billed or located, but you can
recieve calls in an almost totally secure way.  Now you must keep in mind that
this is only half duplex, so the modem is out of the picture, but for voice
communication, from anywhere in you city and most likely ajacent cities, this
is the best thing since sliced bread!  Now you can assign yourself as many
different extensions as you want, and I would recommmend changing them fairly
frequently.  Also try to be away from home and/or on the move when calling,
since this will reduce the chances of being located if they should somehow
become suspicious.  About the only way they will is if you do bill long distance
numbers to the Repeater, or if you dominate the airtime on it.
  Once a month the owner of the repeater goes out on sight and gets a usage
log.  Usually calls are limited to 3 minutes, so the average call is 2 minutes.
Now, if you're dominating the system, the average call is going to be quite
alot more than 3 mins, and he's going to know something strange is going on.
Of course, all he can do is change the password, and we all know how 'secure'
that is... hehe.
  Now there are also companies (real bastard ones, who deserve to be fucked)
that run mobile like it was cellular, and charge minutely.  Now these guys are
EASY to fuck with, since you can create yourself an account, take it off the
minutely billing cycle, and just don't make LD calls, only recieve calls... Wala
now you have a RADICAL phone, which will most likely never be discovered (mine
hasn't been for close to 4 months, and boy is it nice!).
  Now one note on this... Usually it isn't the cops who deal with this, it's
the FCC, and believe it or not, they actually do get the job done fairly well.
But this by no means says it's dangerous... On the offical Vindicator Danger
scale this only rates a 3... And even lower if you're cautious.
