Unknown dasher 2025.16 kHz
« on: September 29, 2012, 1221 UTC »
I have what appears to be a dasher that is not on my list of beacons.  It looks like it has been on continuously since I first saw it about 40 minutes ago, but it has faded to undetectable a few times in that time.

1125 UTC    2025.16 kHz   0.9 sec spacing (67 dash/min), dashes about 0.16 long

Is this one that has been around for a while but I just missed?

09/30/2012  0200z signal above the noise floor.

I strongly suspect this is in the southwest of the US someplace, I would say probably in the California High Desert or right around there.  While I did not hear this beacon during daylight hours it came up out of the noise pretty much as soon as the sun went down.  And since I was hearing it slightly after sunrise this morning I don't think it can be much east or west of me.

(edit)  Faded out about 1345z, right about local sunrise.

Ahhh, the dusk to dawn would explain why it comes out of the noise so quick at sundown and goes away so sharply after sunrise.  I was thinking that was an awefully sharp rise out of the noise and now I know it is just turning on and off ;)
