26995khz FM mode digital

[SCPD]

I found this signal enclosed as a audio link to let you hear the signal I heard here in Oklahoma City. It directs to a audio clip sharing site called Clyp.

I searched on google 29.995mhz FM and it came up with a 29.995mhz radio kit and a picture of a remote control car in another search result. Without any previous experience hearing this type of signal I felt i should ask the community to verify.

(It was recorded with HDSDR and the timing between bursts are actually farther apart. HDSDR records bursts when squelch is on seems faster than actual timing of the signals heard)

I recorded the actual signal in the waterfall in HDSDR but file to big for RR forums.

26995 or 29995?

26.995 is often used by radio control, but it's also used by short range paging systems, often the restaurant pagers.
the audio clip you provided sounds like a paging system.

Yes 26.995mhz

I recorded the RF in HDSDR here is the wav file. 100mb in size. Not compressed.

Put the file in HDSDR's MyDocuments folder.

When loading into HDSDR make sure you tune it to 026.995.000 on the bottom where it says TUNE not the LO. Use FM mode.

The file reads 27175khz. That is because I center the dial on 27.185 with a 10khz offset. 027.175.000 is the LO. HDSDR always uses LO frequency when it labels a file it records.

Stop your radio before playing the file or HDSDR throws an access violation.
