[sdiy] 3394 thanks!

[David Moylan]

In the CEM datasheet there's a note in the last paragraph of the VCO 
section that the tuning may be nonlinear at both ends of the tuning 
range and that it should be compensated for in software.

This may or may not cause you trouble, depending on what you're trying 
to achieve.
