Hello Stefan, sorry, I didn't realize that you are transmitting 'EbNaut', what ever this mean, at least a frequency shift modulation 'BPSK'. And therefore is a distance of 5mSek to less. I hope, that

Hello Roland, No problem! Good luck for your transmissions. Maybe there will be a few more VLF grabbers and even more transmitting stations soon, i hope. 73, Stefan Am 24.04.2016 22:44, schrieb Rolan

Another success. Copied 'DREAMER' at rank 3, Eb/N0 = +0.8, BER 34.5%, constant reference phase. Signal averages 16.04 dB in 54.8 uHz. A good result, considering the overnight noise. -- Paul Nicholson

Hi Paul, VLF, Wonderful! I like the long messages. The next one will be even longer. You may have noticed that there was an 'issue' again with my system. This time the power supply collapsed :-) But

Hi Paul,  Stefan I hope i have solved the problem. The antenna current with 332mA was to much. The Amplifier switched off. Now I am using 240mA. and try again. Transmission was running the last 2 hou

Paul, sorry. Even with 240mA the transistors went to hot, about 120°-130°. I finish. Perhaps you can look for the last 2 0r 3 hours. A nice evening. Roland Am 25.04.2016 um 20:04 schrieb Roland Brues
