Your signal reached the high water mark of 20 dB s/n in 28 mHz last night. Capture at 
http://www.w1vd.com/grabber.html .
Thanks to good condx (DST of -15nt and low static levels) we can put a check mark next to June!

Jay, LF,

This night i will continue with LF transmissions, same procedure.
So far the conds in EU and to 4X are excellent!
Maybe we can make it this night to W1...
