Dreamers,
 
VLF may be difficult these times, but cert= ainly not=20 dead!
 
During the traditional fieldday = near=20 Bamberg, we raised=20 a kite at

At DK7FC in Heidelberg (170 km) we ha= rdly=20 overcame the QRN, but there is indeed a hint of yesterdays dash on the 6000=20 window 
 
To my surprise, both transmissions were cl= early=20 picked up by Paul Nicholson's "miracle loops" at 980 km, and can be se= en=20 on

Good luck to Chris for today's=20 experiment!
