LF,
Regarding my WSPR settings, the power is not a correct evaluation at the
moment. My Tx power is about 5 watts but the ERP will be very much lower &
as I have not calculated it as yet I have just inserted -27dB.
When I make the calculation I will insert the correct figure.
Cheers,
Gary - G4WGT.

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 ?

Is there some sort of unofficial bandplan on this band?
Oh no!
Please let's not get into this again....
At the moment there is no bandplan, but general concensus would
indicate "beacons at the band edges - real QSOs in the middle".
The current WSPR activity around 503.5 (502.0 dial) seems reasonable,
although moving up a few hundred Hz wouldn't hurt, say to 502.3 dial
which gives a 200Hz window at 503.7 - 503.9
There are often CW mode beacons near the bottom of the band - GI4DPE,
GW3UEP and others, and it's convenient to have them there - it allows
monitoring them and SK6RUD concurrently.
That's just my view on how things have evolved.
"Real Man's CW" seems to live around 502.63
