You can get the foundation with 2x 1hr visits to a local club. They absolutely don’t want you to do this, they really want you to join but it’s possible.
I got my foundation in 2015, 10watts even in a solar minimum Like just now is plenty.
I have a wire fan dipole strung up around inside my loft and i can do everything i want to on 40m band or above.
I’ve had untold hours of fun with gnu radio and a hackrf.
