Strange Signals

[thadood]

Ive recently stumbled across a group of 900mhz frequencies that seem to be using encryption of some sort. the frequencies are some where in or around Matagorda county texas and i couldnt find any database information on them.

926.04375
931.0625
929.5125
929.0625
929.5875
929.7375
929.8625
929.6125
929.6625
929.6125
931.5125
931.8625
931.86875
931.8875

Ive included a sound sample of the stream, if any one can identify what this is i would greatly appreciate it.

That's paging, lol.. Pocsag and FLEX......

 

[thadood]

what are those paging systems typically used for and in what application?
depending, but on other frequencies in the list the patterns are way different , still some simularities but definatly never the same

They are the pagers you see people carrying around.

Can thier signals be decoded into numbers and text ?

 

[SkipSanders]

Just like cellphones (same law), it's illegal to decode common carrier paging. Unlike encrypted voice comms, it's POSSIBLE, but not legal.

Can thier signals be decoded into numbers and text ?

It's very easy to do. Illegal in the US, but easy none the less.

Its against the law here in the US but...... if you would like to study paging decoders for "academic purposes" then Google is your friend...

Winflex, poc32, PDW, among others....

2.16 is the most recent version of PDW AFAIK, and is my favorite.......for amateur use/testing only, of course.
