Bill's Re-Born 1993 ColorBurst Michigan Mighty Mite

So far we've sent out 9 of these color burst 3.579 MHz crystals. It occurred to me that I should make sure these particular rocks work with the Michigan Mighty Mite design we've been advocating. So today -- still in something of a turkey-induced haze -- I pulled out the surviving remnants of the MMM that I built back in 1993. That one had been for 40, so I rewound the coil for 80 using the data from this MMM site: http://www.qsl.net/wb5ude/kc6wdk/transmitter.html

I was hoping that this rig might oscillate even without the variable capacitor, but mine did not. Once the cap was placed in the circuit, the oscillations began. It sounds pretty good on my Drake 2B.

I have not yet wound the secondary (antenna) coil but (as I suspected) the oscillator works fine without it.

So, no excuses folks. These cheap junk box crystals work. Time to build one of these things and join the ranks of hams who have homebrewed a transmitter (and, of course, The ColorBurst Liberation Army).
