Paul and Markus, Nice work! Given the good phase SNR I looked for X-ray events correlated with the phase bump at ~ 11:15. There was a ~ C1 event at about 10:20, which I'm guessing is ruled out by the
"... thinking about the costs and merits of kites and balloons." Kite/balloon = helikite, which provides interesting low-cost options for stable one-man deployment and operation, especially if a pick
Markus, Nice signal! A question perhaps for Paul or yourself follows: At ~0.22 fT (estimated from Paul’s spectrogram) I expected to see >> 10dB SNR in 278uHz. 10dB SNR is off scale so I looked
Paul, Thanks for the excellent and definitive insights. I will enjoy running the trials that you suggested (30-minute Speclab trial running now with 3kHz bandpass, hum filter, blanker, and test signa
Stefan, Nice work, I think of 510 km at 6.47 kHz as a new frontier in part because modal (Hollingworth) effects are so sensitive to (everything?) at distances and frequencies in that neighborhood. LW
Stefan, Congrats on the ULF/QRP innovation and result! I'm sure that your interest is in pushing the range but since your remote site is 3.5km away I thought I'd mention something interesting about r
Congrats Markus! Could that 20dB increase be mostly from ERP? If so then I would be able to detect here overnight at 5 - 10 ft/rt-Hz. Jim AA5BW Huge signal, over 20dB stronger than normal here in Tod
Wolf, Thank you, I will capture per your suggestion some images (and rms measurements) of jitter between the Thunderbolt E and other GPSDOs at four or five time intervals in case this information is
Wolf, Thank you, that is great news (10us pulse compatibility, and 25ns standard deviation). I have an E-MU 0202 so I will use the (192kHz centroid 4x interpolated windowed-sync-filtered) setup that
Stefan, Nicely done, efficient design for your high-quality winding. 73, Jim AA5BW From: [email protected] [mailto:[email protected]] On Behalf Of DK7FC Sent: Monday
