An inefficient speaker wire magnetic loop for 7 - 28 MHz

My magnetic loop videos have always been popular so here's another. It's made from thick speaker cable. It's good in that all the connections are soldered but poor in that the wire won't be as good as solid copper. But the loop is quite light and portable. 

Here I try it on various frequencies between 7 and 28 MHz from both home and away. SSB was unsuccessful but digital modes worked, including a JS8 contact made on 28 MHz when the loop was indoors.
