It was all trashed and recycled parts, except for the 13.560MHz crystal, that was provided by Fearless Fred. (A very nice donation, indeed!) However, I'm not using that anytime soon. Why??? The 22M Beacon freaks went apeschytt on me. Even Glenn Hauser e-mailed to me that it was a bad idea for me to use this mW AM TX. So, O.F.W... However, it was a neat and fun experiment, for a while. So, what's next? An old idea, coming of new, again. A Layman's, Plug & Play, AM Carrier-Current, Medium Wave, Transmitter. And, we have several existing choice ideas to build prototypes from. Stay tuned!!!!!! (Literally.)

You get very many more miles-per-watt with a CW signal than you will with AM. Another thing to consider is the fact that an AM signal typically takes up about 3 to 6 khz of bandwidth. That being said, what the heck, give it a try. My guess is you'll need a lot more than 2mw to be heard much beyond your backyard.
Experimentation is a good thing. 8)
