I need to build some small tracking transmitters (using a circuit similar to
http://www.jbgizmo.com/page4.html
This circuit uses a fifth overtone crystal to get an output in the 216 to 220
MHz range. The circuit is rather finicky about the crystal and transistor...
most don't work.
Smaller and more rugged crystals are preferred. Does anybody know of a place
that can make 1 off crystals in this range for a reasonable price. Many of
usual suspects don't seem to be able to make crystals in that range.
