Bob, Tonight I’ve been estimating your SNR* at 15-minute intervals and comparing to your SNRs from last night. For the large majority of the 15-minute intervals your SNRs were higher tonight, a

Bob, The attached plot shows some interesting aspects of the 74.54xx kHz links on Sunday night / Monday morning. Aspects that caught my attention as grabber images arrived from Henny, Hartmut and Mik
Tobias, I have been working on cancellation of power-line noise and impulsive noise, so I was interested in your comment about W1JT's new blanker. By "SVN-server" do you mean developer.berlios.de ? (
Chris, Sounds intriguing. You're near the portion of the near field referred to as the reactive field (sometimes as induction field which is less precise but pertinent here). At your 1km distance, co
Bob, This is puzzling; it doesn’t seem to be attributable to any of the usual suspects , including Dst indices, terminator, equipment. Atypical in many ways from historical trends of your signa
Bob, This is the third time that I’ve noticed Dex’s signal peaking substantially (>15dB?) starting around 0500, at approximately the same time that your signal begins a substantial fade.
Mike, I have a mix of practical, theoretical and scientific knowledge on this subject, but would not consider myself a leading expert. Judging from the questions that you listed and the proposed roug
Hello Uwe, I am on travel in a low-noise location, and will have a low-noise VLF RX set up and running by 0300 UTC Saturday (seven hours from now). I’ll plan to leave the RX running for at leas
Yes Bob, I originally attributed that noise burst around (2200?) to cultural noise local to Hartmut. Seemed too strong and broad to be a traveling wave. But your comment had me reconsidering; and I t

Bob, Dst Index hasn’t stabilized since October 30 disturbance, and if memory serves it took a bit longer (6 days?) for your signal levels to fully recover after the last 3 disturbances. I know
Did anyone switch on at ~ 1045 UT in the neighborhood of 8969.76 kHz? I don’t see anything on the VLF grabbers so I’m guessing it’s QRM or someone not too far from my Arizona locati
