Ok, thanks for looking. Tonight the signal will be at least 6dB stronger than Saturday so maybe there will be a trace. The transmitter is on since 19:18 and I will try to stay on until 00:00. -- Pa
Many thanks Markus and Domenico. I'm really pleased with that. I make that about 2022 km. A distance record for me! Maybe that is the farthest EbNaut on MF so far? My callsign decodes with Eb/N0 = -0
Hi Paul, again congratulations becouse i got some more better decodes. Here the results by playing only with nominals time & frequency offsets: UT Eb/N0 sym Eb/N0 carr Rank 2045 NIL 2100 5.1
Hi Paul, for your analisys, in this folder there are .wav files recordered during the EbNaut test of yesterday night: https://www.dropbox.com/sh/9c3nnw40nyb5pqc/AABZ6oPxpAY4IwuWFmebMSfba?dl=0 These a
Dear friends, in the Paul's 21.15 decode (screenshot of my previous mail) i made a mistake in entering the time offsets. I wrongly used comma instead of dot to separate decimal value. So decode for
Well Done! The photon flux is on: 477.7 kHz, EbNaut parameters as before (10 chars 8K19A 752 1-second symbols starting on the half hours UT) Hope you have better luck if you want to try again, Markus
Good luck Joe. I've held the MF record for 24 hours, that's long enough - over to you now. Thanks I downloaded all the .wav and have been playing with the decoder and looking at the in-between carri
... watching again since 20 UT. Unfortunately the frequency is currently affected by a 200 Hz wide slow-Hell test transmission, but this will hopefully not last all night. All the best, Markus (DF6NM
I wrote the other day about seeing a transient that I thought was bouncing off the primary center. Now after dismantling and measuring a few things I find that transient was reflecting from the LPF w
Consider using a Tee input low-pass filter, so the PA sees a series inductor first, rather than a shunt C A shunt C input will give large current spikes when hit with the square wave from a voltage m
Hear, hear, Alan. And can you imagine the mess they will create if they get their mitts on Openreach! 73 de pat g4gvw Alan G3NYK Will close down at 01:00 with the last EbNaut at 00:40 and tomorrow I'
Congratulations Joe and Markus! A new record, I make that 4555 km and with a dB or two to spare. That's really is a milestone for coherent at MF. I wonder if the propagation would stand longer symbol
Hi Markus and thank-you for your patience and coaching. I was only there to put your ideas into practice. I feel bad for making Paul's record so short lived, but very grateful for his software and gu
No worries, I have a lot of satisfaction from seeing the software doing its job and being used to push the limits. It will be interesting to see if 2 second symbols decode near 3dB better than 1 sec
Hello Joe, Propagation was excellent last night, albeit with deep fading. See attachment. The background noise was increased due to static rain, visible as green horizontal bands. Easy aural copy. 73
