18.0 is the crystal you need. Covers 18.000 to 18.200 including all of
18.068 to 18.168 MHz. With direct dial frequency read out. The actual
crystal frequency is (18.000 - 3.155) / 2 or 10577.5 KHz. If you can't
find one in stock at Burghardt, Surplus Sales of Nebraska, or from
someone on this list, International Crystal Mfg Co of Oklahoma City is a
reliable source. Not inexpensive but known to be good.
