With possibly 3 stations active this coming weekend (Stefan, Ossi and Gerhard) close to 8.970kHz we need to avoid QRM. It could be quite hard distinguishing between stations only a fraction of a Hz apart using QRSS and DFCW.

Hello Nicolas, VLF!
Interesting! I saw traces of OE5ODL´s transmission on 8970.02Hz and FB Gerhard´s transmission ( at least +12dB S/N) below 8970Hz. It was the first time , I saw two VLF signals together. 
Todays wet and foggy weather is not problem for VLF wawes Veselý obličej

Hello Dreamers, maybe the ODL's VLF transmission but I did not have enough time because it was during my lunch raises labor. Reception in QRSS600.
 
OE5ODL could you schedule one transmission this week-end with email via RSGB to informe all.
