[SMCARA] Classroom Demonstrations

[Daniel Metcalf]

For modulation I have thought about building a couple circuits with
test pins so the students can see the carrier,
input and modulated signal for both FM and AM.

Amateur Radio has something for everyone. Even if it is just peace of
mind that no matter what happens your message will get through.
