I updated the breadboard from earlier today....

I hooked up the LM386 to the SA612, removed the 7.030 rock, and replaced the rock with the signal generator. I am now able to hear lots of signals from CW to Shortwave. Since I don't (yet) have a bandpass filter I am hearing a lot of spectrum.

Short Audio Clip (The audio is rough, but there are only 13 parts on the breadboard.)

I will need to model some filters for the project. That might be the next experiment.
