LF: Re: US 500-kHz band plan

["James Moritz" <james.moritz@btopenworld.com>]

Dear LF Group,

So, as far as trans-atlantic band-plans are concerned: It appears that there 
isn't actually a common frequency range that all stations on both sides of 
the Atlantic could use for WSPR beacons or anything else, so the shared WSPR 
segment is really a non-starter. There is nothing actually preventing use of 
the 501.0 - 501.2kHz range in cooperation with WD2XSH stations should they 
wish to, but there does not seem to be any great advantage to using this 
frequency from the point of view of other US stations, for whom 
split-frequency working would be a necessity in any mode.  Since the UK 
allocations are currently experimental, and the long-term form of the band 
may change, it would seem sensible to continue with ad-hoc frequency 
arrangements as we have at the moment.
Cheers, Jim Moritz
