472kHz WSPR RX

About 5 minutes ago I QSYed to 472kHz WSPR RX. Already 3 stations spotted with best DX  LA8AV (1035km). It is still quite light here.

UPDATE 1608z: Now 4 different stations spotted on this band this afternoon.

UPDATE 2053z: 11 different stations spotted this evening on 472kHz WSPR RX.

472kHz WSPR analysis by PA1B

Bert, PA1B, has done some analysis of my 472kHz WSPR to see how little power (ERP) would be needed to be still copied. Of course, this assumes reception is not external noise limited.
