VA3LK is Q5 here day and night in Helena, Alabama USA. I'm certain that 
quiet a few East Coast
Lowfers would be happy to look for European QRSS signals, esp. with longer 
dot lengths. There
are several stations on the East Coast that are well equipped for the effort.

I suggest cross-posting a request on the "Lowfer List" which can be done by 
e-mailing
a message to:

lowfer@qth.net

Good luck to all involved in the effort!
