 I have a vid of the AM transmitter modified to use a 27mhz crystal, I used chopped audio instead of the tone, as the 13 tones just do not work. The transmitter is a Ramsey AM transmitter kit, you have to bypass the output bandpass filter to use higher freqs.
The video was to large to attach, so I just copied the audio from it. Listen at 14 seconds!
