Hi All,
In agreement with John & Graham, I believe that makes sense. The top part of
the band is probably the least used area so we just need to agree on a 200Hz
slot of either 503.800 to 504.000KHz with no guard band or 503.700 to
503.900KHz with a 100Hz guard band.
My WSPR beacon is now active using dial frequency 502.000KHz & 503.550KHz
data.
Looks like Andy just beat me to the announcement.

John,
Looks close to my post , just, as wspr is such a narrow mode, could move to
the band edge without problems
clear of the occasional qrss slightly lower down
With a move to vfo/exciter control, defining the wspr slot is a reasonable
concept as it will allow other 'casual'
monitor stations to be established .. and negate the number of post needed
to announce a test !
What of the beacons that used this area of the band , are they qrt or just
sleeping ?
