Unknown signal at 900 Mhz (Geauga County)

Hi,

I am new to the site, so I apologize if this is in the wrong discussion board. I am located in Geauga County, Ohio and came across an unknown signal at 931.337.500 Mhz. A waterfall of the signal is below. The bandwith of the signal is about 15Khz and it has a digital'ish sound to it. When active, the signal is pretty short (about 1-4 seconds) and it comes at irregular, but still pretty routine, intervals.

Does anyone have any suggestions / clue as to what this signal may be? Thanks for any help!

It's a paging base station. Probably FLEX or POCSAG. They are on several frequency ranges between 929-932 MHz and also on other VHF and UHF bands.

931.3375 is American Messaging pagers, they have transmitters all over Ohio:

Data format is mostly FLEX, with a little POCSAG

Thanks for the help! That's what I was thinking when I was researching that frequency, but the waterfall didn't look like FLEX/POCSAG so I was unsure. I will give that a try. Thank you!
