No the Ten Tec radios prior to the Omni V and Paragons
all use a permeability tuned VFO. Mechanically it is
just a "slug" of ferrite material with a thread in the
inside of it, the VFO knob then simply turns a
threaded rod that is inside of the slug and makes it
move in and out of a coil. So short of physically
locking the knob itself from turning there is no
simple way to do it "electrically".
