If I understand the schematics on Jon Smicks site correctly, here
Figure 3 seems to be the audio modulated transmitter, the kind we could use to broadcast with.
the only difference seems to be in the modulation section. No modulation section, you’ve got a beacon. With a modulation section (which apparently can be something as simple as a transformer, though I guess that’s not ideal) you’re broadcasting.
I agree that adding a shortwave side would be a blast, and the antenna situation is totally different, which would add to the fun.
Do the electronics guys you know have any suggestions for us?
