[TenTec] T-kit #1252 experiences??

[Bill_Ames@hyperion.com]

Does anyone make a receiver that hears and translates audio frequencies
above 20khz into the audio spectrum?

Dave;

No you didn't waste time in HS Physics class.

Included in the 1252 kit are additional parts for conducting experiments.
One such part is a Germanium (I think) diode for just such an experiment.

Audio is audio and RF is RF. They share a range of frequencies, but the
velocities are different. An audio amp will amplify RF yes, but without a
detector (demodulator) you wouldn't hear anything except perhaps a hiss,
or did I waste a lot of time in High School physics?
