Hi,

Working on converting an old CB to a 10 meter beacon. Obtained some
xtals in the correct range I need, but they have 3 leads instead of 2.
Are these resonators? Can I use them as direct replacement for xtals in
the CB radio? Where does the 3rd lead go?

BTW, if anyone has a schematic for a barebones 10M tx, 1W +/-, please
send a copy if you can with parts list.
Tnx!

Use an ohmeter to see if one of the leads is connected to the case
of the device. If it is, it certainly is a ground lead....
I have seen regular xtals with the third lead used as a case ground,
as well as xtal filters, which normally have a ground lead...
