Hi Paul, VLF, That's amazing! A 'SMS' via VLF over ~ 25 wavelengths distance on the 36 km band, from a fixed antenna, in less than a day and without stacking! Again i think back to 2010 :-) Such a re
Wow! Nice work all. Jim AA5BW Hi Paul, VLF, That's amazing! A 'SMS' via VLF over ~ 25 wavelengths distance on the 36 km band, from a fixed antenna, in less than a day and without stacking! Again i th
You made a good choice of symbol duration. The error map is at http://abelian.org/vlf/tmp/170525e.png We might do as well or better with a daytime slot 05:00 to 21:00 to avoid the night noise and two
Hi VLF It is going to be hard to keep this rate of achievemts ;-) Congratulations to all the team involved. Really motivating experiments Indeed harder than EME !! First man used bands revisited with
Still no decode. The correlation peaks at 20.44 dB in 12.6 uHz with offsets +2058 seconds and +0.1 Hz so it looks like the settings are correct. I'm using the sample rate 0.5143924/sec from the WAV i
Hi Markus, Paul, It was a long transmission with relatively short symbols. Apart from the accuracy that is required for the timing there is also a higher requirement for the accuracy of the frequency
