10 MHz Rubidium FE-5680A

As a 10 MHz reference for microwave transverters, I've found the "barefoot" FE-5680A to be unsuitable for microwave transverters due to low-level audio-frequency phase modulation on the output. To use the FE-5680A with a microwave transverter it is necessary to "clean up" its output by locking another crystal oscillator to it as described below.
