Ovenized crystal oscillator frequency stability

E. Schrama @ ejo60.wordpress.com uses an Arduino and a DCF77 time signal receiver to test the stability of an ovenized crystal oscillator running at 1 MHz. In this experiment I will use an Arduino and a DCF77 time signal radio receiver to measure the stability of an ovenized crystal...
