Nick,
Basically, what a reflex does is takes the detected output (at audio
frequencies) and passes it back through the RF amps, this time using
them as AF amps.
I think Neville had a nice one in the contest about 2 years ago.

I don't intend to use the Star Roamer in the DX contest. I agree it can't be taken seriously as a communication receiver, but it is 'cute' and interesting as a first intro into short wave.
