Low Power Radio on YouTube

Some of our fellow experimenters have taken the time to post their experiences on YouTube – awesome! I found several that seemed to merit a share, and many more are likely there or soon to be added.
Anyone from here thinking about a vid?

|Basic component flow chart and how to get set up. Basic operation with what you get in your order to more serious studio info for later expansion. Installation is not as difficult if you review the instructions carefully and plan accordingly.|

|Here you see how our system sounds on the road. In the winter your peak transmitting window is limited but you see here late in the afternoon our unit breaks through the noise.|
|In the late 50’s two young friends built and ran their own low power AM broadcast band radio station. The Voice of America doccumented this venture. This is that documentary.|
|In this breadboard project I have the 555 running at about 600KHz and putting an audio signal on pin 5 and an antenna on pin 3, it becomes an AM transmitter.|
