REQ: Long Range Systems - Restuarant pagers?

[chudgoo]

I went to Panera Bread the other day and they handed me one of those pagers used to tell you when your order is ready. I immediately looked up the FCC info and found it uses 467.75MHz.

Also it seems someone has done some leg work decoding it and it looks fairly straight forward. POCSAG at 2400 baud and uses FSK. http://www.windytan.com/2013/09/the-burger-pager.html?m=1

It would be fantastic fun (once or twice anyway) to light up the whole stack.

(That said, I’ve never worked in retail/food service, but can imagine I’d be super confused if this happened on my shift... one of the commenters on the last link had a better idea. When waiting for a table, set yours off early and see what happens. Before anyone gets mad, the firmware is called “havoc”, is it not? ;)

Hahaha yes red Robin has these also I would have fun with this

POCSAG RX and TX are already done, so all that would be needed is a special POCSAG TX mode which would transmit address-only messages in a defined range ? Or maybe -50/+50 around a given address ? A friend noticed that some MMCall pagers used POCSAG also, but the messages had a text payload.

@furrtek this video explains how LRS works https://www.youtube.com/watch?v=ycLLb4eVZpI He does it on a HackRF I would love to see this implemented in Havoc (as in being able to specify the pager ID and restaurant ID)
