160m FT8 RX with the earth-electrode "antenna"

Someone suggested I try 160m FT8. Tonight I did (it is still on) and it is amazing. It is far better than I expected with lots and lots of stations spotted. Noise floor is very low and already 4 continents spotted. A very brief CQ (2.5W) was spotted by 7 stations with best DX OZ2TF (726km). It is a good match to the FT81ND without an ATU.
