This has definitely been on before, but as we approach sunspot maximum (and beyond) a timely reminder is in order.
This works remarkably well and can be made very inexpensively, yet will bring in stations across the world most days. It may be built "dead bug" or, if you are really keen, as a simple PCB. As I have said before, it would make a great club project on a PCB. The circuit is simple, so a single sided PCB should be straightforward. It means the "big rig" is free yet 10m FT8 may be monitored.
