[TenTec] GPS and Ten Tec Rigs

[Carl Moreschi]

Even if you could bring the GPS 10 mhz osc into the Omni VI, this would not
fix the Omni VI frequency accuracy.  The Omni VI also uses band crystals for
each band.  The errors in these band crystals would not be corrected by the
10 mhz osc being perfect.
