My 10m and 6m WSPR stations have now been closed down. I have turned on my 630m (472kHz) RX kit on for the evening and overnight, this time I am RX only with the preamp. My antenna is again the earth-electrodes in the ground. My view overall is the preamp helps with weak signals but most stations are not too weak! In theory it would be good to have some very weak stations active on 472kHz WSPR. Really, I should give OPERA another try.
My 630m (472kHz) RX was turned on about 1945z.
