630m band WSPR

Neighbourstation PA1SDB Peter requested a couple of times if I could do some receive tests on 630m. He recently started to transmit on 630m with a Raspberry Pi. I didn't have much time for radio last couple of weeks but yesterday evening I managed to set the FT-817 on WSPR 474,2KHz and attached the loop only to the center of the PL connector. After some fiddling I managed to receive some WSPR stations.

Best "DX"was EA5DOM over more then 1700km. Peter also requested for a OPERA test. So I will probabely try this evening or in the weekend.

Some pictures of Peter's setup can be found on his QRZ page. Additional pictures of the antenna system he uses below.
