Aside from being in the 80 meter ham band (which could stir up a posse) there was something vaguely familiar about this frequency back in the cobwebs of my mind. Then it hit me, the old NTSC TV color burst frequency was 3.579545 MHz and there were always plenty of those crystals around to build an 80 meter QRP CW transmitter with. A little tweaking of the crystal frequency and there it is. Hmmm....
