With the impending trip and uncertainty of where / how I can set up an antenna I experimented with about 10 foot of wire from a 9:1 nun up to the window and down to the wardrobe. Far from idea but it’s surprising just how far I got with no effort and 2.5W on 40m FT8:
There is one 10m hit there too but I did not transmit in earnest. But the 10m reception plot is even more impressive:
I can see how this “let’s throw a bit of wire up a tree” can become rather fun!
