Unknown data sound near golf course.

[Dispatrick]

I picked up this data noise while passing the golf course near my home.

I don't recall exactly which frequency it was listed under their license as I forgot to jot it down when I took the recording. 457.XXXX Mhz

When I drive by later I'll remind myself to make note of the frequency it was and edit the post.

Thanks!

Its 1200 baud AFSK data with 1200/2200 Hz tones.
Probably some type of SCADA.

That's very likely irrigation control or something similar.

If it's actually coming from the golf course. Otherwise it could be a lot of things.

Show up on the 9th green at nine o'clock, and see if it gets stronger then. Make sure to dress nice.

Yeah Sprinklers. I found something similar a couple years back at a couple of my local city parks. What's this Data signal I keep getting in the Evenings?

A lot of the golf courses use these sort of sustems, I use one of them as a "testing data source".

@YalekW Also said before it was some low baudrate POCSAG

The audio sample posted at the beginning of this thread is not low baud rate POCSAG.

I once had to track down some interference to the UHF Florida Turnpike repeater system and it took us all the way to a golf course in Dunedin Florida. There we found a base station transmitting data continuously with no license. In followup, found the golf course bought some system that tracked a GPS terminal on the golf carts and also permitted golfers to send emergency as well as service requests (3 martinis to hole 9) from the cart. The company (located in Texas?) that sold the equipment insisted they had some nationwide FCC license and therefore their customers (Golf Courses) did not need a license. I had to set them straight.

Actually that is not POCSAG at all.. Just some scada thingy. Probably closer to mckennas response.

The PGA may be monitoring the dress code on the course.
