Sorry, pressed "send" too soon by accident!

As I understand it, there are not yet any formal Europe-wide proposals, just 
what individual regulators have allocated on a case-by-case basis. I think 
G, EI, and ON have all allocated 501 - 504. The DL beacons and OK0EMW are 
licenced to use spot frequencies around 505kHz. Gus SM6BHZ would be able to 
use 504.0 - 504.1kHz.

But the main thing is whether we over here should transmit around 504kHz as 
we are now, or shift to near 501kHz to share a common WSPR segment with the 
US. On one hand, keeping to near 504k would have the advantage of no strong 
signals in band for those trying to receive US stations. But on the other 
hand, it might mean we get QRMed by "general comms" US stations for those 
trying to receive us, and anyone wanting to receive both US and EU stations 
would need two receivers/soundcards, etc.
