472kHz WSPR

For the last hour or so I've been on 472kHz WSPR using just the feeder up to my VHF/UHF beam. Part of the run is along the ground and the antenna is only about 6m AGL. So far, no-one has yet spotted me but I have spotted DK7FC (669km) 7 times so far and M0PPP (182km) 3 times. As usual, I am using my homebrew tranverter. ERP is very low milliwatts with this inefficient antenna.

I may leave WSPR running on 472kHz overnight to see what happens. Tomorrow I will try another "feeder" antenna. This is my first MF "outing" for many months.

UPDATE 2210: DK7FC and M0PPP spotted more times and now F1AFJ (607km) has just been seen.
