The audio clip you posted sounds like either a paging system or a trunked radio channel to me.

Motorola eh? If I buy a MotoTRBO radio is there any way I can use it to "receive only" like a scanner or does that TRBO system use a combination of 500,000 possible privacy codes? I know it's not encryption but I am under the understanding that it's a flavor of CDMA with some kind of code that is set by the end users when they set up the system.

It is becoming quite popular here in Ontario from some public services and even one fire dept so far.

Looks like Toronto and area is all going 700mhz P25 with probably encryption in a couple of years by the way which is terrible news for us who work in news
