Modern radios have *zero* VFOs in the classic sense. But if you're willing 
to grant that a fixed frequency oscillator and a tunable synthesizer is 
equivalent to a VFO, then surely every full-duplex satellite transceiver 
has at least two. And if you're controlling the radio in full-duplex mode 
for satellites (this is AMSAT-BB after all) then you have to deal with both.
