>From the K3EXREF manual Introduction: The K3EXREF option locks the K3's reference oscillator frequency to an external 10 MHz source by automatically controlling the REF CAL function. While locked to the external source, the K3's reference oscillator frequency is maintained within 2 Hz. Since the K3EXREF does not phase lock the K3's reference oscillator, the external 10 MHz source has no impact on the K3's phase noise performance. For best performance we recommend your K3 be equipped with the KTCXO3-1 high stability (0.5 ppm typ.) reference oscillator.
73, Ron AC7AC I've been following the thread on using a 10 mHZ external reference and the prospect seems both affordable and at least initially fun BUT I'd like to ask is it really a practical improvement over Elecraft's available KTCXO3 internal 1ppm reference? Or is this just a way to achieve more accuracy at less cost than the KTCXO3 ? Isn't the K3S better served with its own oscillator? What am I missing here?
