pulsating sound on 4810
I'm hearing a pulsating sound on 4810Khz with AM demod. Stronger at
night, so it's not local. QTH is SF Bay Area. |

Here is a good web site to identify digital signals
click on a suspected mode and it plays the audio thru your computer http://www.wunclub.com/sounds/ And another one at URL: http://www.kb9ukd.com/digital/ And another http://rover.wiesbaden.netsurf.de/~s.../DIG_intro.htm Have fun with the mind boggling sounds -- CL -- I doubt, therefore I might be ! |

They play havoc with 60 meters. Whatever it is, it's a broadband sucker. Goes from 4785 to 4810. Sounds like two carriers getting FMed. "Swish Beep Swish Beep...".
