QSYed to 630m WSPR

At about 1950z, I QSYed to 630m WSPR RX. A couple of stations immediately copied with several more shortly afterwards.

UPDATE 2044z: Already 6 unique stations spotted with best DX EA5DOM (1525km).

UPDATE 2214z: 10 uniques so far tonight. For a little while I have gone QRT to let my shack PC batteries charge. Later, I'll run the shack PCs from batteries again, so I have a lower noise floor.
