I was playing around with my RX350 last night when I came across a very weird signal. Unfortunately, I don't have recording capabilities, so I can't post an audio file. Anyway, the signal would begin with what sounded like Morse code than end with a weird "BRRP" sound, almost like the ringing you hear when you call somebody on the phone. I checked back in at 0600, and it had switched to 6316.0, where I found it again this morning at around 1300 or so. I've never heard this signal before. I also stumbled across numerous high-speed Morse stations:
04906.0 (at 0559)
06488.0 (at 0531)
07047.5 (at 0533)
