The 8719 can use either the 11.1125 crystal, with pin 10 grounded. This setup is found in Uniden-made SSB CB radios like the 5-pin Uniden Washington, Cobra 142GTL, Realistic TRC490 and a few others.

Or it can use the 11.325 crystal with pin 10 left unconnected. This was used in SSB CB models that had a second IF frequency of 455 kHz for AM only, the so-called "dual conversion" models like the Cobra 148,2000, Uniden Madison and others.

The MB8734 can use only the 11.325 crystal.
