Thanks Markus, It is already dark and the TX is not on! Let's try a longer message, shorter symbols and more power. Will advise when QRV. 73 Joe Fewer and weaker decodes than the night before: Â VO1
Hi Paul, That's very helpful. The oscillator needs some work to improve our chances. 73 Joe Given a 3 hour VO/VK window, http://abelian.org/ebnaut/calc.php?sndb=15&snbws=92e-6&code=16K21&sp=10&L=1&nc
I was going to do it every hour, but didn't want to keep anyone waiting. Good luck Andy Joe Every half hour ??? Andy On 2 December 2015 at 21:00, <[email protected]> wrote: Hi Paul, That's very helpful.
... indicates that it takes 4.66 hours for one window. You don't need a spectrogram, just a single 3 hour spectrum. Both ends would need GPSDO and also PPS at the rx soundcard. And even then we don't
Well, that was quick! The message appeared while the progress indicator was still showing 0%. But it was quite strong at the start of the 22:00 transmission, fading below visibility (0.12Hz B/W) towa
I ran last night's signal through vtmatch. First I retrieve 14 hours of signal and mix down to baseband I/Q at 100 samples/sec. vtread -T2015-12-01_19:00,2015-12-02_09:00 /raw | vtmult -f 2777 | # 13
Hi Paul, that's an interesting plot! Presumably the carrier is not really interrupted, only the frequency seems to be slightly off. The first few spikes show a regular alternating pattern with ~180°
