Nothing compared to the 'Fog from Frog'
covering that end of the band ....?
wspr never was any use on 500 due to long tx times
and high local ground wave propagation , someone
should take a look at the 5 meg system and
take note , one short pulse , job done ..

Subject: LF: 500kHz WSPR
Some time ago some USA WSPR TX stations moved from 503.9kHz on 501.1kHz to
avoid RX blocking of local WSPR RX station., This allowed both USA
stations (listening on 503.9) and European stations (listening on 501.1)
to copy WSPR DX without RX blocking by local TX stations .
But I noticed that in the following time more and more USA WSPR RX
stations moved down to 501.1kHz too. And as a result some (at least one)
European WSPR TX station moved down to 501.1kHz too (to be copied by the
USA WSPR RX stations that moved down) and is now blocking the Europeans
listening here.
So it seems that the RX blocking problem is back :-(
I guess this was not the goal ...
