[digitalradio] Weebly-warbly on 80m?
Listening this morning (Monday) in the UK on 3633 kHz at around 0300 UTC, I heard a strange weebly-warbly digital signal that continued for at least 15 minutes without a break (then it sent me to sleep). The striking characteristic of the signal was that the data rate was very low (a few bits per second?), and the transition between the tones wasn't sharp -- it seemed as if each tone glided gracefully up/down to the next. At first I thought it was ROS, but I haven't heard ROS like this before. Any ideas on provenance? -- 73 Ian, G3NRW

IT WORKED !! This is part of a sinister plot to take over the world. First it puts you to sleep ... z... then I take over. BEWARE !! I assume you were on LSB? Could have been WISP on 3.5926 USB which puts the carrier on 35941 +/- a couple hundred kc. It almost sounds like a steady tone, you have to listen carefully to detect that it is not. It would also have been JT-65 on 3.576 USB, +/- a few hundred kcs. Lots of activity on JT-65 around 14.076 USB. All data modes use USB. JT-65 and WISP sound very different from each other. Time to adjust your (foil) hat. ve3bdr From: Ian Wade G3NRW Sent: Monday, August 30, 2010 5:51 AM To: digitalradio@yahoogroups.com Subject: [digitalradio] Weebly-warbly on 80m?

It was the distinctive gliding from one tone to another that made it stand out from anything I have heard before. -- 73 Ian, G3NRW
