160m FT8 RX (not)

Yet again, I was going to be monitoring 160m FT8 RX overnight. As WSPRnet was working, I QSYed back down to 472kHz (630m) WSPR RX

Once again, all 160m and 630m reception was on the earth-electrode "antenna" in the ground. With this antenna my noise floor is S0 on 160m and 630m. At 160m and 630m, I think this acts as a loop, with best reception E-W. It works well on 160m TX too with the best DX over 1000km with 2.5W from the FT817ND. On 160m the match is excellent.
