WWV and BPM China and... something else? on 10 MHz, 4/27/2010 @ 0828 UTC

WWV (Fort Collins, Colorado) and what I believe is BPM (Xi'an, China) as well as a second time signal beep I don't recognize heard alongside the other two. Recieved on 10 MHz using a CountyComm GP-4L (aka Degen DE202) pocket radio with about 10 feet of wire clipped to the whip antenna, location Williamsburg, Virginia, USA. April 27, 2010 beginning from 0828 UTC.

BPM (the higher pitched of the two beeps) and the other station faded out after a bit, and later on I almost completely lost WWV, but then WWVH came in much more clearly before fading out leaving only what sounded for all the world like a ticking clock or pocket watch buried in a swamp of noise. (i.e. two ticks per second, rather then just one like with WWV/WWVH... more of a "tick-tock tick-tock" sound, and not a beep sound like BPM)

Sadly, I didn't get that on tape as I was falling asleep by that point, and it was also pretty far down in the noise. No idea what that one was, perhaps a European time signal station? I see a lot of conflicting information online as to who else currently uses 10 MHz. ATA in India seems to no longer be in operation, and JJY in Japan doesn't use 10MHz anymore... maybe LOL in Argentina?

Hi, i sometime get Observatorio Nacional (Brazil) on 10MHz mixed with WWV or BPM (depending on conditions / time of day of course). They have a second tick and a ten second beep. Also Russian RWM from 9996 is breaking in when that one is very strong. I have never heard LOL, unfortunately...Thanks for this video, very nice. 73
