Tiny magnetic loop does 7 and 10 MHz WSPR https://stream.echo6.co/videos/watch/2f230bef-3c1e-477e-acac-ce97dd18bad4 The SummerLoop works well for SSB operating on 28 & 50 MHz. It can resonate on lower frequencies with a larger capacitor but isn't very efficient. Still, that doesn't stop it being useful as a small WSPR antenna. In this video I add a compression trimmer and use it for WSPR transmissions on 7 and 10 MHz.
