Hi VLF, I'm back from LF for a while and built up my large VLF coil which was used on 2970 Hz in the beginning of the year. Actually it is under maintenance, one of the six stacks has to be replaced.
VLF, After nearly 8 days the carrier is still on the air without an interruption, despite occasional thunderstorms :-) It looks like the SNR is suffering by summer QRN, as expected. The stable carrie
Yes the signal is definitely making it to Amberg! This is a fine result of mutual collaboration: Stefan DK7FC erecting the transmit facility and posing the low frequency challenge, the DL0AO team (sp

Hi Markus, VLF, The carrier is quite stable now. The QRN has been a bit lower today and yesterday. Maybe the worst days regarding QRN are over now? I'm curious to try sending an EbNaut message but no
Here's the best I've got so far, using the daytime signal http://abelian.org/vlf/tmp/170808a.gif Not a significant signal but we could take it as a hint that something is there. This is H-field only,
Hi Paul, Thanks for the image and efforts. And for the advice on vlfrx tools. It will take some time to apply all that. Without the E field (on your side) we may loose a few dB these days i guess. Se
I'm measuring about 0.016 fT daytime, 0.045 fT nighttime. Daytime signal phase leads the night phase by about 67 degrees. Combining and normalising day/night signals and excluding the terminator peri

I made a change today, now the difference is worse, 0.22 dB. This is typical, two steps forward and one step backwards. If I didn't have two independent receivers running side by side, I wouldn't be
