Circuit design by Ray Ring
The audio is playing through headphones here, so you can’t hear the excellent signal quality
I didn’t have the OpAmp called for in the circuit, so I built this audio amplifier designed by Dean Segovis: http://hackaweek.com/hacks/?p=131
The antenna was a piece of wire about 30 feet long.
An air variable capacitor was used for tuning.
More to come…
