This popular item doesn’t seem particularly friendly for ULF-VLF; 40 to 76 turns wrapped around the home’s water main pipe, ~ 2 amps out, sweeping 1 kHz to 20 kHz every 50 milliseconds. h
Any recommendations on hardware and software for DX reception at 5kHz-20kHz? I have good antennas and preamps (< 1uV/m/root-Hz, < 1fT/root-Hz), USB audio interfaces (> 110dB DR, 192ksps), spare lapto
Mike, Yes, the fading is very interesting; this is the third night in a week in which fading differences between signals from Dex and Bob, of perhaps as much as 10 or 15dB, have been observable, and
Bob, You’ve been visible on Hartmut’s grabber for the last hour or two; I see a just-completed S4 Jim AA5BW From: [email protected] [mailto:owner-rsgb_lf_group@blacksheep
Bob, Nice signal! I watched Hartmut’s grabber tonight (thank you for the dropbox Hartmut); it was quite interesting to watch the day to night dynamics, especially between 2300 and 0300. Your si
Thanks Hartmut, I don't have an RX front end for this band yet (any recommendations?), so I appreciate being able to watch for Bob and other WG2XRS stations via your new grabber. Bob, good luck tonig
Stefan, Thank you for your findings on 630m SNR vs. time during magnetic disturbance onset. The resolution of your data and your narrative details highlight fascinating characteristics. 73, Jim AA5BW
Laurence, Great photo; hope moose doesn’t reach pot first; could that be residual ionization from Bob’s signal last night? Jim, AA5BW From: [email protected] [mailto:owne
I’ll second Mike’s motion of fascinating, including Bob’s perspective on relative SNR between captures by Hartmut, Henny and Mike. On long-term average one might expect a path loss
Congrats Bob and All, Nice work on TX and RX signals, and capture. The four contiguous callsigns are a thing of beauty, especially at the near-threshold SNR level which says something about the stabi
Bob, Mike and Joe, Am I inferring correctly that Bob's signal became visible at about 0600 UTC in Newfoundland and Hertfordshire, remained visible in Hertfordshire until about 0615 UTC, and remained
Mike, I had not yet seen your message below when I sent mine. Your message answers my question regarding the E-W path to your QTH. Do you have any thoughts on the emergence of Bob's signal at Joe's l
Interesting, the signal came up at Laurence’s QTH shortly after sunset, nighttime path between Laurence and Bob, and (based only on overland and over-water loss, not considering RX, cultural no
