Key stages include a germanium diode mixer, 20 MHz crystal controlled local oscillator (I actually used 10 MHz crystals and doubled) and a beat frequency oscillator using a 3.58 MHz variable frequency ceramic resonator oscillator (used on 7 MHz harmonic). Video includes demonstration and circuit description. A full article appears in 'Amateur Radio' June 2013.
