Yes, Happy New Year to everybody. May the happiness always surround us, like the radio waves that we love to receive! [Non-text portions of this message have...
Hello, I am listening to the meteor radar of the Air Force available here; http://spaceweatherradio.com/ There are some abnormalities at time that seem larger...
... Thomas, (Very nice. I didn't know this meteor radar was here. :-) I'm watching the meteor radar now using SpecLab. Just saw a group of 5 or 6 evenly spaced...
FYI, http://www.spacew.com/ has posted this notice concerning upcoming solar activity: "Latest Geomagnetic and Auroral Activity Updated: 01:50 UTC 31 December...
Hi John there is another day to go but this looks like a bit of a damp squib. The max Kp from Boulder was 3 and the Dst barely dipped to -15nT, though there...
... Alan, Thanks for the update. Has anyone tried the Proplab 3.0 software which is sold on the spacew site? It is claimed to do ionospheric raytracing. I...
Hi John, I have had a friend model the ionosphere for LF and provide me some data, but I think it works on electron densities up to the F-region. As I ...
John, whistler propagation modelling would mean solving magnetohydrodynamic equations in the plasmasphere/ionosphere. Basic for that are again charge carrier...
... Ernst, I'm still wading through Chap 3 of the Helliwell book (1965). I have a degree in physics, but it's still hard for "outsiders" to grasp because he...
John, sorry there are only abstracts available from this workshop. I have done some calculations based on Appletons equation trying to model the terminator...
... I've just discovered FDTD (finite difference time domain) recently myself. It seems to be great for finding local exceptions to the otherwise linear...
Has anyone tried this device? I'm having trouble installing one on two machines here, both XP SP3 (even when reverted to SP2), but it installed immediately on...
Hello All, Is it possible to use a potted plant as an amplifier of vlf/elf/other natural activity which can then be logged by a computer? Where I have seen...
For what it's worth, the Quadrantid meteor shower will be peaking on January 3, 2009 centered around 1250 UT. Activity could come some hours before or after...
Hello Tom I don't believe you are too far off here, I am not really sure but I remember when I was in engineering class the professor had a strange hobby that...
Hearing about whistlers quickly went out with my portable. But sorry no whistlers within 10 mins. Only few tweeks and very cold fingers now - so quickly...
... on ... scroll ... I have been playing the Air Force meteor surveillance radar feed that Tom Olenio found (http://spaceweatherradio.com/). I put some ...
... Just saw (and heard) a big, long S-4 whistler on the Todmorden feed. Also am seeing very strong tweeks with curious faint pre-cursor and post-cursor images...
Same here now Ernst - occasional tweeks, but no whistlers in 52°07'N 8°25'E . The signal from the receiver (standing in the snow-covered meadow) sounds...
I listened to the Bielefeld feed for a few minutes. Didn't hear any whistlers. No tweeks either, which strange because the Todmorden tweeks are very strong,...

Some very nice long whistlers coming in, but a long wait between each. I've activated some extra stereo pairs for a trial. http://abelian.org/vlf -- Paul...
Paul, The "stereo combo" section is missing. Did you comment it out, or maybe there's some syntax glitch. [Nice to see all six live feeds active at once]...

And Sheffield has gone silent again - Mark? -- Paul Nicholson --...
... We're receiving the Sheffield link here in Florida (@2137Z). The Stereo Combo section has returned with one stereo pair: Sheffield/Bielefeld. John/AF4EX...
Hello, I've been messing about with my rx as you can tell, trying to get rid of intermod which I have, adding more lowpass filter. Then the blooming snapping...
