Thanks for posting this link, I've spent at-least an hour playing around with this! Gives me something to do as I'm really ill right now with the flu. There's some weird stuff on this, if you checkout 26950 kHz FM, there's a somewhat regular pulse/beeping (tagged "pager"?). The sound can actually be heard further up and down the spectrum; you can hear it at 26850 kHz and 27000 kHz. It makes a very distinctive pattern in the waterfall too, sometimes also adds a line. I wish I could decode this

Do you know if the protocol is encrypted (probably not)? Might be interesting to see what's being transmitted. I'm fascinated by radio communications, actually I wanted to use something like GNU Radio or similar to experiment with this. No idea where to start, I have zero electrical engineering experience.

No idea, never known much about pagers other than someone I know's "beeper" going off for a hospital shift while "on call". To get started I'd suggest buying an RTL USB dongle (rtl2832u) and downloading a copy of SDRsharp (SDR#). That'll give you standard FM and AM range, picking up a HAMitUp will allow you to reach shortwave. Buy a costly HackRF if you have the coin to blow on curiosity (got mine after dabbling with RTL & a HamItUp)
