Strange Signals
While scanning the 25 meter SWBC band, I noticed some strange signals
between 1830 and 1930 UTC. Sounded like time pulses every other second when compared to WWV. Strong in both AM and USB, only barely audible in LSB or lower sync. Incredible range of // oddball frequencies: 11098.5, 11220.7, 11342.1, 11587.1, 11648.1, 11709.2, 11892.5, 11953.5, 12105 (underneath WTWW), 12136.6, 12190.1, 12228.2, 12442.1, 12503, 12533.6, 12686.3. I finally gave up, so there are probably more. Some frequencies might be off by 100 Hertz, since i was using an old Sony ICF-2010. Also, some were incredibly strong, others sounded further away. Any ideas? Mike, Louisville, KY |

Did you record the signals Mike ?

Any ideas? Mike, Louisville, KY Maybe a harmonic of a CODAR buoy? Fading could be due to time of day conditions. -- http://bit.ly/g2PCII- Hide quoted text - - Show quoted text - CODAR has more of a ping to it than these pulses had. Mike |

Did you record the signals Mike? Nope, I sure wish I had. I'll have to look for them on another day. After thinking about it, I'm leaning toward some sort of telemetry. Mike |

Any ideas? Mike, Louisville, KY Turn your microwave off. :-) 1. With really good propagation, some of the various shortwave maritime surveillance radars might be showing up for far away. 2. I'm getting a bunch of crap on the higher bands these days, but it's local. The last time I tracked down this particular crud, my closest guess was either an ultrasonic rodent repeller or some construction equipment battery charger. Didn't feel like knocking on doors and asking my neighbors if they had a bad rat problem. I remember reading some ads for pest repellers where they bragged about the extra added electromagnetic radiation feature. 3. It's that season when your neighbors are draping their eaves with well lit interference antennas. Mark Zenier Googleproofaddress(account:mzenier provider:eskimo domain:com) |
