LF EbNaut & Markus,

There is a definite post sunset opening to Europe from the NA East Coast.

I have modified my station to overlay a 10 minute CW ID (off-on CW modulation at 20 wpm) on the EbNaut message stream.  Will be interested to see what effect it has on decodes.  Am still transmitting a 5 character text message as before.

Tnx es 73,

Rob - K3RWR

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.
