GPS Locked Variable Frequency Reference

This page refers to my GPS referenced variable frequency RF oscillator published in the Sep/Oct 2018 issue of QEX. All updates since publication are here.

This project can generate any frequency between 500 kHz and 40 MHz with an accuracy approaching one part in 109, for example 0.01 Hz at 10 MHz. Total parts cost is about $150.00.
