Wow! Paul, do these results meet your standard criteria for confirmation? 73, Jim AA5BW http://abelian.org/vlf/tmp/170828a.gif That's two daytime signals, 25th and 26th 10:00 to 20:00, combined coher
Congratulations Markus, 73, Jim AA5BW 11.6 dB S/N in Todmorden, http://abelian.org/vlf/tmp/170905a.gif That's -78.6 dB in 2.5 kHz, after sferic blanking. 1028km, a record distance for this band I thi
Markus, I'm very sorry to hear of your loss, and will remember Gizmo. The loyalty and unique empathy of our small friends is a gift that lives on. 73 Jim Markus, Very sorry to hear of your loss. Some
Joe, Did you try the "[0] Interpolated PPS signal" option? ("Sampling Rate Detector" window, "Scope Option" drop-down menu) 73, Jim AA5BW Paul Markus and Group, Thanks Paul for the reports. The radia
Stefan, The attached doesn't show noise vs frequency vs season/distance very well, but examples include: a) Colorado data seem to suggest less reduction in noise as frequency decreases from 9k Hz to
Hello Paul, I'm guessing that you've considered all of the below but just in case: Erratic power supply startup related to the comparatively high source resistance of long wires and associated connec
Hello Paul, Based on the those additional details, it might be worth a quick check of the voltage-loop stability margin: if for example your load draws 50 ma, briefly add a 390 ohm 2W resistor across
Hello Paul, By noise from light do you mean shot noise from the average solar flux? I tried a quick calculation yielding < 1 nV/rt-Hz, and I guessed that your noise voltage density is more than 10x t
Based on Marcus' request for all-day carrier at 17470.1000 Hz and Paul's report of -38.55 dB in 1Hz in Forest, Virginia, I'll keep a SpecLab window open at 17470.1000. I installed a receiver with GPS
Repeating (with apologies) and adding to (see last paragraph: wondering about Forest/Arlington raw data correlation) a recent message on this perhaps more appropriate thread: Based on Marcus' request
Paul, Receiver is at 38.915547, -77.124948 8 hours raw data ~ 11 GB if I calculated correctly. OK to use raw data from SpecLab running in Windows? No need for EbNaut? Which program do you want to use
Stefan and Paul, All up and running per details of your suggestions, thank you. Started 192 ksps .wav file at 1500 UT. Spectrogram integration time ~ 12 hours, centered at 17470.1000 Hz Antenna beari
15 seconds initial download to Firefox here, quick hour/date scrolling thereafter. Looks/works great! 73, Jim AA5BW Yes, same here. It just takes a few minutes until everything works as expected. Run
Amazing; congratulations to Dex on T/A message length record and excellent signal, and Paul and all others on great set of receiver decodes. Among the coverage spans, (Hawley, TX, upstream, all overl
Congratulations W4DEX, IK1QFK, Paul and all others on the new record; fine work, and inspiring. 73, Jim AA5BW --Original Message-- From: [email protected] [mailto:owner-rsgb_lf_group
