If T/A is of interest it seems like a three frequency slot system would be
benificial.
slot 1) EU beacons (not attempting a QSO)
slot 2) USA beacons (not attempting a QSO)
slot 3) EU/USA stations attempting a QSO on the same frequency (for
convenience in digital modes)
Slots 1 and 2 should not be combined as 'local' interference will preclude
reception of T/A. A similar three slot system could be used for cw, although
operating 'split' on cw is less of a problem than on the digital modes.
The WD2XSH bandplan eats up large chunks of spectrum by unnecessarily
handing out frequency allocations to all stations. Past performance within
the XSH group has shown that some never got on the air and many others
haven't been on the air in years. Only a very few stations are regularly
active. We would be better served by an 'open' frequency slot system as
outlined above. It doesn't appear the WE2XGR station will be following the
XSH band plan as currently laid out.

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.
