All looks good, antenna current stable at 0.34 A. The message will be repeated 13:00:02 to 14:25:22 73, Markus From: Markus Vester Sent: Thursday, March 10, 2016 10:22 AM To: rsgb_lf_group@blacksheep
Between the two EbNaut sequences (10:45 to 13 UT), I had sent a straight uninterrupted carrier on 8270.0025 Hz. This looked clean on my own monitor (which is referenced to the same GPS as the TX), bu
An easy decode Eb/N0 = 1.7 dB, BER 34.2% and the phase pattern was -30 -30 0 0. Carrier -55.8dB in 2.5kHz after sferic blanking. Decoded with Eb/N0 = 0.0 dB, BER 36.9%, phase -30 -30 0 0, carrier -56
Hello Markus, Thanks for your transmission. Unfortunately i got no copy in both messages. The QRN levels were quite high :-( Your carriers were visible, with lower SNR though. Maybe a receive loop wo
Thanks a lot Paul, it's good to see your reliable decodes. The carrier data is helpful, and we can see that some irregularity must have occured before 12 UT. Interestingly my Loran-C monitor, which i
Paul and Markus, Nice work! Given the good phase SNR I looked for X-ray events correlated with the phase bump at ~ 11:15. There was a ~ C1 event at about 10:20, which I'm guessing is ruled out by the
Thanks for the hint Jim! Hoping to be able to blame Mother Nature rather than my own transmitter, I inspected several MSK traces in DF3LP's valuable archive http://lf-radio.de/cgi-bin/fh/show_wf.cgi?
There was a small wobble of the DHO phase at about that time - about 3 degrees peak at 10:24 - and it didn't last long. Except for that there were no other disturbances. A pity really, that might hav
