Re: LF: LF and VLF EbNaut

[Markus Vester <markusvester@aol.com>]

Here are the Bavarian decodes from last night's sesseion. Eb/N0 values derived from symbol error rate and carrier power were sometimes rather inconsistent so both are mentioned here. As expected, the quiet DL0AO site is generally a few dB better than mine, decoding VO1NA consistently in every single slot.

I was amazed by the early start from Canada. At this time of the year, such northerly paths are apparently close enough to darkness almost around the clock. My 100 kHz monitor shows Loran signals from East China rolling in already around midday here.
