- Tapping Long Distance Calls
- FNF of Group 42

- This phile appeared first on the Group 42 BBS in 1987, then again in the
- Group 42 publication of Hacking, Cracking, Phun and Games -- FNF
-
- A satellite dish can be lots of phun watching all that shit, but few people
- know it can also be used as a wiretapping device. All you need is your
- basic home satellite system, also know as TVRO or televison receive only.
- What you need to do is turn to the AT&T satellite known as Telstar 301.
- You'll notice between channel 20 and 23 you will see a blank screen as if
- there was a station there. You won't hear anything except maybe an
- occasional garbled sound.
-
- This blank screen contains 12 MHz of phone calls, each phone call takes up
- only about 3.5KHz of this bandwidth so quite a few calls can be packed on
- one of these birds. What you do to listen in to these calls is the
- following. Take a genral coverage shortwave receiver and hook it's antenna
- to the video out of the TVRO receiver. Make sure your satellite receiver
- is either on channel 21 or 22. Set your shortwave reciever on lower side
- band (LSB) or turn the BFO on. You will now be able to tune between 1.6Mhz
- and 7.5Mhz picking up more calls to Hawaii, Puerto Rico, Alaska, and the
- Caribbean than you ever though possible. Who would have dreamed there
- would have been that many phone calls to listen to?
-
- About every 3 1/2 Kilohertz there is a phone conversation. If you do not
- hear a phone converstation you will hear a trunk idle, a continuous 2600hz,
- tone. Since these are inband analog trunks you can acutally listen for a
- click and a string of MF tones followed by a ring!
-
- For frequencies above 4.1 MHz, it is best to switch to upper side band.
- Also you can tune in Channel 8 of telstar 301, this seems to be US Sprint
- service form the mainland to Hawaii. Sprint Codes can be gotten
- successfully by listening to the calls.
-
- Telstar 301 can be found at 96W on the satellite dish. Spacenet 2, which
- is located at 69W is all US Sprint. Domestic calles as well as overseas
- calls can be monitored. Other intresting satelites are ASC1 at 128W, Westar
- 2 at 79 W, and Comstar D4 at 76W. On these, simply tune across until you
- hit a blank channel that looks like it's carrying a signal. Then tune the
- shortwave receiver anywhere between 1.6 and 7.5 Mhz. If the conversation
- doesn't straighten up swith to LSB or USB on the shortwave.
