UPDATE 1424z: 451 stations have now spotted my 10W with UA9MA (4630km) being the furthermost to the east. On 20m FT8 RX 420 stations spotted so far.
Stations spotting my 10W FT8 to the tiny loop on 20m today |
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

There have been Es openings in Europe on 10m and 6m, but nothing yet to suggest my 10mW ERP 8m WSPR would be copied. This is the power that ...

I think this is amazing! It makes you wonder about the theory of mag loops that it all depends on wire/loop diameter and getting connection and conductor losses down compared to radiation resistance. I wonder sometimes about this particular loop having an unbalanced ground that 'could' bring to resonance the rig/computer and wiring ground. I guess to verify that this is not the case, an experiment attaching a ground wire that is laid out in the room to rig ground should be performed. If you have to re-tune the loop to bring it back to a low SWR after doing this then it is possibly due to this loops unbalanced ground. If not, there is something missing in our understanding of small loops and conductor losses. I actually hope it is the later. Jay, W5OLF
