| Stations spotting my 2.5W to the earth-electrode "antenna" in the ground on 160m FT8 overnight |
In all, I was spotted by 55 stations as the maps shows. 73 stations were spotted on RX. The furthermost on TX was OH6BG (1716km).
My theory is this works as a loop in the ground, so that the efficiency should decrease as the skin depth goes down, so I would expect it to be poorer on 160m than 630m. Also, I was using FT8 which is some 10dB poorer than WSPR. Overall, very pleasing.
This begs the question - what is it like on 80m FT8? If the match is OK, I shall probably try this tonight!
This is experimentation I can still do! At some point I must try my 2200m (136 kHz) beacon on QRSS. I think it can do QRSS. It is over 10 years since I last used QRSS.

Will try to rx you on 80m this evening. We might even try to make a contact. I got a pretty good and sensitive system on 80m. 73, Bas PE4BAS
Hi Bas -Thank you for the 80m FT8 QSO this evening. 73s Roger G3XBM
