Hi all, It's time for a new EbNaut transmission. Another attempt to get a decode from IK0VVE or IZ7SLZ and of course also for anyone else who is interested :-) f = 8270.100000 Hz Start time: Thursday

Good decode here as well. This transmission came just in time for me to test a different setup, using samplerate lock to DCF77 rather than 1pps. I'm using a cheap Delock USB sound dongle with VIA VT1
Thanks Markus, Jacek and Eddie for the decodes. I'm planning a new message for tonite but still need some time to build up a new PC into the VLF TX system. The old one has 512 MB RAM, the new one has
Here, Eb/N0 = 16.2 dB. 26.73 dB in 34.7 uHz. Here in E-field I get carrier S/N: 20.79 dB in 34.7 uHz. I'm impressed with your E-field reception Eddie, it's always a dB or two better than mine. I coul
Hi Paul, Maybe it's worth to play with alternative E field antennas and compare them to the one you have? Eddie is using one of the small active antennas. In some situations they can give better resu
... since 0:35 UTC, a plain carrier is running on 8270.005 Hz. I'm going to run it for the night. Maybe someone can see it on a spectrogram. The new PC works perfect with the GPS module it seems so f
Looks good, the "glitch rate" on wald5 seems to have gone down from 4 .. 6 per hour to less than 1 per hour. Also a nice peak here in my DCF77-locked 31 uHz instance (attached), as well 477 and 63 uH
As well as these special cables, dont forget (if you are in the UK) to replace your 13A flat-pin mains plugs and sockets with the good old 5A round-pin ones. Some years ago there was a heated corresp
If you look at my Grabber, don't panic Mr Mainwaring. Dropbox seized up at around 19:45 last night. I didn't touch Dropbox, although I am working on replacing it due to them changing my account facil
DR friends, there's a weak trace on my grabber... quite strong sirocco wind at the moment is shaking my loop antenna and noise is increased. EbNaut SL session is running, too. 73, Max IK0VVE ________
My Grab upload is now changed, a slim version has been performing OK on test so my normal page http://www.g3zjo.talktalk.net/vlfgrabber.htm is now showing current 424uHz and 47uHz at VLF1 and VLF2. L
Hi Eddie, I see you can even see me in 424 uHz. You must have a very good antenna design ;-) I'm also impressed by your results over that 742 km path, http://no.nonsense.ee/qth/map.html?qth=IO92NG&fr

Good decode again. The signal was strong enough to produce a visible haze around 8270.1 Hz on my grabber. The EbNaut phase dots (referenced to DCF77) seem to show a small step upward around sunrise ~

Hi Eddie, Markus, Thanks for the decodes, your results are very good. Hopefully the message can be decoded by Alex too. Rain caused the aborting of the early transmission. Tonite i want to try 10 ch
