Hi Dave,
The short answer is NO !
There are two types of FE5680's. The older style used an ANALOG
approach to controlling the Rb. The newer version changed the circuitry
so that frequency control was done with a DDS device by means of sending
a digital word to the DDS and thus changes frequency. The digital
version does not permit any ANALOG control.
Bert's board is for the newer style DIGITAL version.
