It's good to get these reports. Many thanks. The daytime sig is visible on your spectrogram though it dips about 1600 ut. Another transmission has been added at 0900 for further entertainment. 73 Joe
Hello Joe, What are the details/parameters of that transmission? I will give it a try now! The antenna was switched back to EW before 9 UTC. I'm late but i will get you! 73, Stefan Am 09.01.2018 22:1
Hi Stefan, Glad to hear that your tree is charged. I've added a morning transmission: Daily, 0900 and 2100 utc, 16K21A, CRC-8, one character, 544 symbols, 1 minute each, 8270.0075 Hz, 0.25A, 30 watts
Hello Joe, I got decodes from your daytime message after 1 day already (when using the optimum list length). It was not so clear, two possible characters were thrown out but one of them was stronger.
Hi Stefan, Sorry, we have to keep trying. The decode was not correct, unfortunately. It seems we lost the mains again some time again today. SL was restarted 2040 ut tonight and the aerial is radiati
Joe Please verify the new EbNaut start time was 2140 UT. Previous post to Stefan had 2040 UT as start time. Tnx for the signal! Jay W1VD -- Original Message -- From: <[email protected]> Reply-To: <rsgb_l
Hi Jay, The carrier resumed 2041 after the mains failure. Ebaut starts 2100 and 0900. Good Luck! Joe Joe Please verify the new EbNaut start time was 2140 UT. Previous post to Stefan had 2040 UT as st
Last three nights very poor T/A reception, noise has been high. But a good transmission - 13/14 decoded at Hawley without stacking. Todmorden (3575 km) -- 28/29 Eb/N0 +11.4 dB, S/N -26.2 dB/1Hz, phas

After a run of bad nights, the signal has come up good again. Todmorden (3575 km) -- 28/29 Eb/N0 +11.4 dB, S/N -26.2 dB/1Hz, phase -175.0 *Decoded* 29/30 Eb/N0 +13.7 dB, S/N -23.9 dB/1Hz, phase -168.
Some good overnight signals recently. Impressive signal early in the morning. The short carrier in between two EbNaut messages: http://78.46.38.217/fbins3.html#p=1516708800&b=290&s=sp&m=cardioid&w=r&

Hi Paul, VLF'ers Thank-you for the encouraging reports. The ERP has been restored to about 0.25 amps after some fiddling in the shed and shack. The EbNaut transmissions at 09 and 21 ut continue. 73 J
Latest overnight results. Bielefeld much better after repairs to receiver. Todmorden (3575 km) -- Average 28/29th to 16/17th: Eb/N0 +7.6 dB, S/N -30.0 dB/1Hz, 17 out of 20 decoded. 17/18 Eb/N0 +8.2 d
Thank-you again Paul for taking the time to compile and post these results. Stefan has suggested a longer CRC might be helpful. Should I give this a try? Have the daytime transmissions been decoded?
