[TenTec] Dumb Omni VI question regarding split A/B

[Peter Bertini]

This is an early Omni VI. I cannot lock A or B VFO individual. If I lock
one, they both are locked. I have tried various combinations of locking A
first, then going to spit, going to split first, and trying to lock one
VFO. I can't lock one without ending up with both locked.

Do I need to upgrade my software, or does my Omni VI have a problem??
