Hello Dreamers, Today it feels right again, i'd like to have another exciting adventure... After the recent successes at 2970 Hz, maybe it is possible to get something through at 2470 Hz? That's the

Hello ULF friends, Now i'm sitting in the car again in the deep forest. It is silent (outside!) and the sky is clear. The TX and EbNaut message is now running: f = 2470.1 Hz Start time: 14.APR.2019

Hi Stefan, DL0AO H-field (E-W): Eb/N0 = 2.5 dB(car), 0.7 dB(sym), DL0AO E-Field: Eb/N0 = 12.0 dB(car), 10.9 dB (sym). Our file ended a couple of minutes early with the last 12 symbols missing, causin

Hello Markus, ULF, Very well. Thanks for your decodes and for sharing the night :-) Do you have an idea why the E-W cardioid result is worse than from the E field alone? Which carrier S/N do you get

Hi Stefan, > Do you have an idea why the E-W cardioid result is worse than from the E field alone? Looking at https://vlf.u01.de/VLFgrabber/vlf9.jpg we find that the noise grew much more on the earth

RR Markus, thanks. Yes, 1.65 kHz is on the list. BTW the message has been decoded from the data of IK1QFK, with > 14 dB SNR. But more later. 73, Stefan Am 15.04.2019 22:02, schrieb Markus Vester: Hi

...after some days of trying, it looks like the signal was to weak to get a decode at SQ5BPF. Maybe Paul is in the same situation. Time to tell the message, it is 'CFM'. Now it will be easier to sear

RR, thanks. Can you say something about the noise (QRM/QRN) situation relative to the recent test at 2970 Hz? Assuming equal noise conditions, the signal could be 3 dB weaker for a message decode. An
