It sounds like some kind of digital mode. Any idea what it might be? The RF frequency I found it on, the demodulation type of the RF carrier that my radio was set on (not the modulation type of the subcarrier for the digital mode, and not necesarilly the actual modulation type transmitted by the source), and the date and time I recorded it on, are all in the filename of the WAV file I saved (and the ZIP file I used to compress the WAV file to make it small enough to fit on here and make sure that it was of the right file type for an attachment which doesn't allow WAV files). Note that the Radio Shack scanner I was using is manufactured to be permanently using FM demodulation (except when set to the aircraft band, which automatically switches the scanner to using AM demodulation) so there's no guaranty that that's the actual modulation type used by the transmitter of this signal. I also have an ICom PCR-1000 (which allows manual selection of demodulator), but it's not hooked up at the moment. But listening to it should give you a general idea of what it is if you are familiar with UHF professional digital modes. So I hope somebody on these forums can tell me what it is.
Found this strange signal on UHF
