More radio projects. I was actually looking for a longwave receiver, but there's various stuff here.

Neat "sampling" antenna for lower frequencies that uses a length of circuit board as a whip with a simple amplifier connected directly to it.

Simple, sort-of-cardioid directional antenna.
Yup, that's about the simplest 2m dipole you can make -- no balun, even. Built one out of 1960s-vintage Rediffusion catenary wire. It works.

A very pretty quad 2m/70cm antenna -- and some interesting mods to PMR radios.
