[Boatanchors] trying to identify a signal on 13.450 Mhz varying to13.400 Mhz

[K0DAN]

I did some listening 8 Oct. 2009 around 2330Z. I'm in the central USA.

I could hear the signal best using AM detector, and it is pretty broadband, 
transmitting between approx 13.378 and 13.606. It is rich in extra 
modulation around 13.342, and it's hard to hear the musical notes if you're 
listening in USB or SSB. Turn to AM and you'll hear flute-like noises.

>From the central USA, using a 10-el log periodic antenna at 75' I heard 
strongest signals (S9) pointing towards the southwest...I can hear the 
signal if point to Alaska and over the north pole, but these north paths are 
3+ S-units down. Signal disappears if I point south, southeast, east, 
reappears when I point northeast & north. Best signal definitely towards 
west/southwest.

I doubt these signals are RF ID...if you listen to the music & rhythm, it is 
a very constant and periodic scanning, such as WEFAX, possibly a radar, etc. 
I also listened around 6.7 Mhz +/_ and could not hear similar signals...also 
doubt these are harmonics.

Interesting....keep us posted!
