How to make a cheap "pager scanner"

[mdmde123]

Pretty impressive

Great video!

[Frit0Pie]

freakin awesome!!! i wonder if this works on cell phones a text messages? hmmmm.

Hot and smart Juanita your killer geek chick! Thanks for the flash back old school hack! I worked on millions of pagers and remember when the first RIM pager hit the market now matured to BlackBerry mobile... 512 baud and 2-tone whoo hooo! This is a cool hack but you can simply use a scanner IF port and have the ability to scan many different paging frequencies specific to your local services.. Still props for the cheap pager hack!

Where can i get a 10 $ Pager ???????????

I just find some for 50 € (from Germany) or more :-S

[TheMCMXXL2]

@TheLion092 Take a old Hauppauge WinTV with analog receiver, they cover the frequency range. No need for any hardware.

Smart and hot perfict combination! :)

How often do you see the code "612"?

[linagee]

??????? IT'S IN CLEARTEXT? hahahaha. no way.

[godofwar691]

what does this type of computer tech does this classify as. i want to learn about this stuff so what classes do i look for etc ? plz can someone give me some incite on this

You still can't beat good old-fashioned serial ports for hacking and experimenting.

The advantage is that you can build RS232 interfaces from discreet components, whereas with USB you tend to need intelligent PICs.

Never could quite get my head around the USB protocols.

OR, just use a cheapie police scanner you found at a yard sale for 50 cents and hook it up to the audio in!

[purplemutantas]

Very cool! Hooray for Hacking! You rock Lady Ada!

I use my pager for emergency responce and I have a poor signal at my home. Some times I do not get the pages I need. Is their a way to boost my pager signal???

[Rohkus]

So when you hack the pager network you can see all private data on there. So... private numbers and such?

[marcan42]

USB serial ports are too slow. They can transfer data fine but they have a high command latency. Reading the flow control lines requires a command each time, and the USB frame period is 1ms, so at most you're going to be able to poll the CTS lines 1000 to 500 times per second.

Basically, USB serial ports are fine for standard USB uses (transfer data) as long as you can tolerate somewhat higher latency, but they're quite useless for bitbanging unless your data rate is very slow.

[Simiload]

@marcan42 its very slow ;)

[ballader1]

@marcan42 That's why you should use USB 2.0 instead of normal USB

[marcan42]

@ballader1 Good luck finding USB 2.0 (High-Speed) serial port chips.

[ballader1]

@marcan42 I already have :-)

[marcan42]

@ballader1 Which chip? The only one that I know of is the FT2232H, which is, quite frankly, overkill.

[ballader1]

@marcan42 exactly that lol

[kd8bxp]

I am interested in the legalities of this? FLEX is a closed protocol so wouldn't the software be doing something that is illegal by decoding a closed and encoded transmission?

[ytdxt]

I think the software itsself is not illegal if the protocol has been reverse-engineered acording clean room rules.

Decoding other peoples pager messages definetly is more problematic.

[frank26080115]

I've never used the hardware flow control pins on my FT232RL, but I've always assumed that they'll function exactly like a real serial port. Do they not?

[ytdxt]

If you want to do it right you should use a microcontroller to do the low-level stuff.

btw.: You also can use a radio scanner with discriminator outout to decode FSK-Data with your soundcard.

[norriszd]

@ytdxt Can you elaborate more on this?
