Joe, Sorry to hear your news, hope repairs are more obliging than Mother Nature was yesterday. 73, Jim AA5BW Sorry to report an ice storm last night. Most of the aerial is on the ground, part is stre
Hello Stefan, Most exciting to see your latest venture, near the 2kHz-4kHz 100km-1000km propagation wilderness (soon after reaching the attenuation summit* at ~ 17,000 km / 17kHz) * (signal strength
Stefan, Congratulations on new TX earth antenna league far-field records including 5170 Hz. Quite exciting, and impressive resistance values. 73, Jim AA5BW From: [email protected]
Hello Stefan, I wondered if peak voltages or peak currents from your parasitic capacitances and parasitic inductances (lab load and/or earth load) could be contributing to the current limit, via: [(a
Stefan, Excellent V, I and time-domain data, a wonderful sight. The inductance extrapolations generally fit an "AWG 18 (on surface) plus earth-loop" model*, which is very nice to see, and the time-do
In the mid 60's I wished that my receiver (BC-453/4/5) would reach 24 kHz. Still works and still wish; that much stayed the same :-) Jim AA5BW How times change. In the late 1960s I received NAA on a
Stefan and Edgar, Best compliments on your continuing fine work. I second Markus's motion, the Excel plots are most informative... and the results are exciting [including the diurnal SNR pattern for
Paul, Probably need binoculars for birds, but with your extra detector you could see your car and garage doors open/close, and catch anyone moving your aluminum tube, as long as any of these objects
Stefan, Excellent news, a great day for ULF! 1570 Hz seems like rough propagation terrain (unpredictable spatial nulls and temporal phase variations at distances less than 500 km); I wonder if the ea
