Direct about-face receiver - a demonstration

A video for those who haven't heard what a direct conversion receiver sounds like for amateur band reception. This is a tune across 40 metres with a homebrew direct conversion set. SSB and CW signals are audible. The receiver is a high dynamic range design inspired by Rick Campbell's R2. It is not single signal so you will hear the audio image when tuning across a transmission. The antenna was a half wave dipole and the test was done from a noisy suburban location.
