Wow! Nice work all. Jim AA5BW Hi Paul, VLF, That's amazing! A 'SMS' via VLF over ~ 25 wavelengths distance on the 36 km band, from a fixed antenna, in less than a day and without stacking! Again i th
Thanks Louis, I hadn’t realized it’s the semicentennial of that great storm; in the long run much good came directly/indirectly from subsequent research, including space weather instrumen
Paul, Thanks for your reply below. In available time I'm trying to verify that FDTD can be helpful for the ULF tests (and vice versa, that the ULF experimental results can validate FDTD for ULF). So
Stefan, Yes, working on a 1E-1 to 1E1 Hz plot now. Very interested in what FDTD thinks 1E-1 to 1E0 kHz looks like. Guessing 1E-1 to 1E0 Hz will be smooth but even in that case it's hard to guess at w
Stefan, Great news, exciting! 73, Jim AA5BW Congrats Stefan! No doubt you will soon get past the near zone with Paul's help. Amazing. 73 Joe VO1NA Attachment: SNR vs Range aa.png Description: PNG ima
Warren, Dixon plans to be on; and EclipseMob.org organizers would appreciate: (a) additional well-controlled LF and VLF transmitter signals before/during/after the eclipse and (b) any before/during/a
Unofficial EclipseMob update: Dixon will warm up starting ~ 06:45 Pacific Time, ramping ERP to ~ 1-2 kW at 55.500 kHz and ~ 3-4 kW at 135.950 kHz by 07:30 Pacific Time, broadcasting MSK 101010..., un
Thanks Joe, Lots of receivers listening. 73, Jim AA5BW Transmitting a carrier on 137.777 kHz +- a few ppb 4 Amps to the 10x100m RL for the next 1.5 days or until something fails. 73 Joe VO1NA On Sat,
Hello Joe, Data from some key eclipse receivers is being processed; using data from good receivers in Kansas and Delaware, analysts did not find your 18:00 UT 137.777 kHz signal on their first try us
Joe, Thanks, we will try one-minute integration; were the westward detections of your 137 kHz signal generally comparatively close to your QTH? Nighttime only? 73, Jim AA5BW Hi Jim, I can only guess
Joe, Thanks! Signals from your QTH to receivers on the other side of the eclipse path will have a broad peak in time, which accommodates long integration times. Based on your comments below, we'll st
