There is more than one PLL in the Omni VI. The 5.0-5.5 MHz VFO is a PLL 
system. The "Band switching oscillators" are also PLL controlled. They 
are separate PLL systems, only the RF output of the two are mixed 
together. The is no interconnected PLL control of both of those oscillators.
In the Omni VI manual, regarding the band switching crystal oscillators: 
"A PLL circuit on the Logic Board .......  sends a D.C. correction 
voltage back to the oscillator....."
