Hi,
I have built a FM transmitter. When I connect it to the computer speaker, and power it up, I hear it in my radio. And by turning the variable capacitor, the frequency changes.
On my frequency counter, DVM13MFC2 from Velleman, the frequency shown is from 30-55MHz, according to the turning on the capacitor.
The question is: Why do I hear it on the radio? Does the radio pick up the 2nd harmonic or something? I'm a little bit in the wild here...
I'm aware of the law and regulations in the 88 - 108 MHz FM range.
