USA 10m WSPR

W4DEX (6390km) appears to be the last USA 10m station to spot my 500mW WSPR beacon at 1806z this evening. I shall probably remain on 10m and 630m through the night but am not expecting much on 10m if I am honest. If anyone spots me on 10m WSPR that would be a bonus. On 630m (472kHz) I expect to spot, and be spotted, by several stations.
