630m (472kHz)

Around 1830z I returned to 630m (472kHz ) WSPR. Initially I used the PC on batteries but it is now on mains power. On battery power the noise floor is low and best RX DX was LA8AV (1035km) in JO59 square. I am hopeful of reaching Norway again on TX tonight (5mW ERP, earth-electrodes).  It would be great to break the 1000km barrier on 630m TX this season, as I have yet to do so this year.

In past years, I reached Finland, which is much further. Another absentee this year is EA5DOM who was regularly copied last season on 630m WSPR. Maybe he is using a different mode or is on 137kHz?

See http://wsprnet.org/drupal/wsprnet/spots putting in "g3xbm" to see what is being spotted.

UPDATE 2000z: So far, only G4FTC (123km) is able to be spotted in my S8 noise  "fog" when I use the SMPSU on the shack PC.

UPDATE 2028z: Yet again, my best spot on 472kHz TX so far this evening is by PA0RDT (243km).

UPDATE 2104z: Still not been spotted further than Holland so far this evening on 630m WSPR TX.
