This is based on a PIC microcontroller controlled ID'er, and N7KSB 10 meter QRP transmitter both found in the 2001 ARRL handbook.
I have received some excellent comments on this project, and it's ability to get out with 500mw QRP. Bill, WJ5O, says he will add me to his excellent 10 Meter beacon list, as "Intermittent". This beacon has been running almost continously through March. Who knows, maybe I'll string up a 10M antenna and leave it in continuous operation. This beacon has done over 7500 miles per watt!
While on vacation in the Carribbean, I got the chance to visit the ship's radio room. The Radio Officer allowed me to use the ship's HF receiver to listen for my beacon. Sure enough, I heard it! What a thrill!
I have reactivated by beacon, in the same configuration as the 2001 test.

Beacon Test - Feb 2001:
I ran my beacon for the weekend of Feb 23, 2001, to see how well it held up to continous operation, and see what kind of reports I would receive. Saturday evening the weather kicked up and got my antenna wet, pulling my SWR off a bit, but it still got out!
