Allison,

You might be misunderstanding. I'm modifying a Midland 13-380 to
transmit in the 10 meter band for use as a CW beacon. The xtal is
9.4MHz to replace the transmit xtal per instructions he
http://www.4sqrp.com/resource/10m_beacon/10m_beacon.htm

Should put the freq up in the 10M beacon portion of the band if I can
hook up the 3 leads correctly and if it is indeed a proper application
for the part.

Thanks!

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!

If you can be more specific on the CB I can give a better answer.
I will assume US AM/SSB radios.

The likley case is a 10.695 crystal filter.

The second likely case is ground lead on common crystal.

IF foreign (outside usa) FM radio then a 10.7mhz crystal filer is
packaged that way. Those filters are available in 4.5nhz, 10.7, 10.8
21.4 and 45mhz commonly and there are others.
