Hi ya'll, I've got a mystery signal I've been unable to identify as of yet. Unfortunately, I've only got the audio recording to work from now.

Picked up in San Diego county area on 447.3225MHz, bandwidth of approx. 6k.
Based on the audio, I think it's a 4-tone FSK, but my ears aren't that great so I'm not certain.

I've scanned SigIDWiki but nothing quit fits the sample I have. I've also tried a dPMR decoder, but either the clip is too short for the decoder to work or it's not dPMR.
Attached are a waterfall screenshot and a link to the audio sample.

Audio: https://totally-not.a-sketchy.site/2gQq2PF.wav

Even just the name of the protocol would be a help, thanks!

on SigIDWiki I see where you upload a signal, there is a list of them, but where is the feedback from people on each signal on their guess? thanks
