Just goofing around with the scanner again, and randomly searching in the 408-409MHz range, I came across two frequencies that I didn't recognize. One might just be an ambient humming sound due to reception, but I'm not sure. The other one, 409.7375MHz, sounds like some kind of trunked control channel (motorboat sound) mixed in with some kind of pulsing beep. The static is bad enough that squelch kicks it, but always at fixed intervals, so I've got a sense this isn't just static, but a transmitter turning on/off to transmit whatever this is.
Thoughts? Files are linked below in MP3. 44100khz, 16bit, Mono original source; non-discriminator derived. I did a quick search on the FCC's sites for all freqs in this range, but nothing turned up.
