Ok all I think that's reasonable ?

I will add a page to the group  and post links
in other news groups  to  it, should
widen the reporting base

From the recent posts
I assume the beacon power will
represent ERP ?

I can make this statement on the page
If it all go's base over apex , there is the 'delete' key option

Are we to  adopt  502.400 Hz  USB dial frequency for WSPR ?
With  1500 Hz audio centre band tone.

RF mid band   carrier frequency of  503.900 Hz ?

With 6 hz modulation and phase continues  tone side bands and
guard band are  not a issue, the band edge is protected?

504KHz  and its sidebands are actually  x2 of the fundamental
so  should not present a problem as the 200 Hz slot is in a
close in, dead zone, there amplitude increasing lower into the band,
one of the reasons qrss and range testing takes place in this
'noisy' zone.

I will add a  note to  the uk500khz group and links in others  with
details
if
acceptable to widen the reporting base.

Tnx-

Graham
