60m FT8 RX

With 2 North Americans and 1 Caribbean as well as loads of Europeans spotted on 60m FT8 in the last day I have reached some conclusions.

1. The earth-electrode "antenna" in the ground works at 60m, but it is much more effective at lower frequencies.
2. My 60m noise floor with this "antenna" is pretty low, although I am in no great hurry to return to this band.
