In case you found the title confusing, these are intercepts of pager text messages sent on 9/11 (possibly leaked from some US goverment agency?). There's no explanation of what geographical area or what network providers are covered.
- blantonl 17y agoThere is readily available software that allows you to intercept pager communications. The two protocols mostly used by the paging companies are FLEX and POCSAG, and the nationwide paging networks all operate(d) on the 929-931 Mhz band. The two most prominent intercept applications are: - POCFLEX, a DOS based software package that requires a 4-level FSK interface to the scanner - PDW, a windows based software package that uses a soundcard to recover the pager text from the scanner baseband. You can download both packages here: http://www.discriminator.nl/software/index-en.html http://www.discriminator.nl/software/index-en.html Most likely someone setup a few radios and archived all pager texts from the different major nationwide paging networks, and then consolidated the data into one set of files.
- yters 17y agois this common practice? why would someone collect all this info at this point in time?
- Kadin 17y agoI suspect, although I don't know of anyone doing this myself, that there are people doing this all the time, just as a hobby or for the hell of it. The equipment required is minimal and so are the storage requirements, so you could easily log everything. Even in 2001 it wouldn't have been cost-prohibitive. There are probably people sitting on years worth of data, just because that's a hobby for them. 9/11 is probably one of the only dates that's of interest to the general public.
