[TenTec] Century 22 Question

[jones_winston at bellsouth.net]

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.
