The Seker
|
|
|
|
Every day, tons of information is exchanged over the air waves. I have
|
|
found news agencies, military computers, businesses, and even hacks.
|
|
The standard method of exchange is called RTTY (Radio Teletype). It
|
|
usually is used at 66/7 words per min. Instead of using ASCII, Baudot, a 5
|
|
bit character set is more widely used. There are many variations of it in
|
|
use also.
|
|
|
|
There are many other types of transmission standards besides RTTY that are
|
|
commonly used. A few of the known:
|
|
|
|
FAX (Facsimile)
|
|
|
|
Helshcrieber- it's used to transmit pictogram-type alphabets (i.e.
|
|
Chinese, Jap, etc.) instead of the American letters.
|
|
|
|
SSTV- is similiar to Viewdata. Used for transmitting high-resolution
|
|
pictures mixed with text.
|
|
|
|
To start, you'll need to buy (card) a receiver (with a coverage of no less
|
|
than 500 kHz-30 MHz and a resolution greater than 100 Hz) and a high quality
|
|
antenna. These can usually be found at electronics stores. You will also need
|
|
to get an interface and some RTTY software for your particuliar computer. Look
|
|
in magazines like 'Amatuer Radio' or 'Ham Radio Today' for more information on
|
|
that shit. Another good place to check is a CB store.
|
|

NEWS AGENCIES-
|
|
|
|
From these you can find all sorts of crap. You may even intercept a story
|
|
being sent to the presses. They tend to operate at 66/7 words a minute (50
|
|
baud). A few of the more common 'fixed' bands they transmit over are:
|
|
|
|
at kHz:
|
|
|
|
3155-3400 3950-4063
|
|
9040-9500 12050-12330
|
|
13800-14000 15600-16360
|
|
19800-19990 25210-25550
|
|
|
|
|
|
An easy way to tell if you have located a news agency is by some lame
|
|
transmission being continuosly repeated.
|
|
|
|
i.e. 'RYRYRYRYRYRYRYRYRYRYRY' etc.
|
|
|
|
This is done so they can keep their channels opened for reception.
|
|
|
|
|
|
|
|
CONFERENCES-
|
|
|
|
Another thing I found interesting was the channels that the amatuers
|
|
congregated around. I frequently ran into people from foreign countries that
|
|
couldn't even speak English. I even ran into other hackers from all over!
|
|
A few of the more popular spots that amatuers hang out are:
|
|
|
|
at kHz:
|
|
|
|
3590 14090 21090 28090
|
|
|
|
at MHz:
|
|
|
|
432.600 433.300
|
|
|
|
at VHF/UHF:
|
|
|
|
144.600 145.300
|
|
|
|
|
|
|
|
PACKET RADIO-
|
|
|
|
A new development in radio transmission is the packet radio. From what
|
|
I've seen, it's just like digital packet switching networks, i.e. Compuserve,
|
|
Telenet, Tymnet, etc.; except slower.
|
|
In fact, Compuserve has been researching a way to transmit its services
|
|
cheaply.
