Thank you Dave (and others who corrected me in private), you are correct I did make a mistake, the 5ppm / 1ppm ( 5E-6 / 1E-6) is relative to the oscillator's frequency, 49.380 MHz, so the actual expected frequency error (tolerance / stability) is as Dave gave above. -Michael, VE3TIX _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
