Don,
I used to have a Century 22. As best I recall, it's a direct conversion rig but
uses a crystal mixing
scheme to get the various frequency bands. Tapping the PTO would give the
correct last three digits in
the frequency but not the correct significant digit. However, by tapping the
mixer output, you could read
the frequency directly on the counter, without an offset programmed in, since
it is a direct conversion.
