Sorry, pressed "send" too soon by accident!

Dear Graham, LF Group,

As the European allocation looks to be wider than the Uk, are we expecting the UK 3 Khz allocation to remain as is, if and when the band is formalised ?, in which case loosing 200 hz may not be the most sensible option ...

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.

Cheers, Jim Moritz
