Hi, I also have a very strong carrier here in Holland on 4623.5 kHz (S9+). The buzzer transmits in full USB nowadays so I don't know if this is related. Check for a live feed of the buzzer http://uvb-76.blogspot.com/ Cheers, Ary On Wed, 29 Sep 2010 22:06:03 +0200, you wrote: >Visit http://mailman.qth.net/mailman/listinfo/spooks to unsubscribe from this >list > > >4622,5kHz is 10 to 20dB stronger than 4625kHz UVB-76 sig here in NE France / >WWL JN29 >JRC NRD545 + 10m LW >no idea of what it is, strong carrier... >Fabien > >Le 29 sept. 2010 à 21:46, Kevin Elliott a écrit : > >> >> Visit http://mailman.qth.net/mailman/listinfo/spooks to unsubscribe from >> this list >> >> Hey folks, >> >> I know there's been a lot of activity on 4.625 over the last couple of weeks >> since UVB-76 went down (possibly for maintenance).
