  • do they still make pagers ?? I use to have one yrs ago before cell phones..a smaller screwdriver might be a good idea..i can't read what is printed on the chips zoom in

  • demod baby demod LOL

  • God what a flash back! Its almost sends shiver down my back. Yes that chip stored the "CAP Code" and most pagers allowed for the service providers to password protect them so other paging companies would not reprogram pagers formally from there company but we found ways to hack the eprom discover the passwords and reprogram them anyway.

  • wait how many mhz?

  • Really good video.. thank you!

  • ahh ur a turnoff

  • I tried this with a pager once myself.

    I live in the UK where POCSAG is the most common protocol - unfortunately for hackers this means the pager's radio only turns on when it hears its unique ID broadcast (probably as a battery saving measure).

    Neat video, and fab ideas on your site.

  • @lawzalexander But wouldn't the receiver have to be on all the time for the unit to hears it's ID? I'm not sure how any pager or data radio can operate otherwise.

  • Comment removed

  • With most pagers the RF receiver is activated briefly every second or two to save power. If the pager detects the long POCSAG preamble (square wave) followed by the start of its unique capcode then it listens for the whole message. Otherwise it just shuts off to save power until the next carrier is sent.

    If the pager didn't have this feature it would be receiving the whole of every POCSAG broadcast, which on a busy paging network would drain battery power further.

  • Girl, you are cool ... LUV U !!!

  • very interesting

    looking forward to see more such videos

  • @usename80

  • Very nice tut. Properly explained in an easy to understand manner. Thanks. Been looking for some reverse engineering projects.
