Re: [Elecraft] [K3] KREF3 External Reference Option

2010-12-24 Thread Don Wilhelm
Eugene, An external reference for the K2 would achieve nothing dynamically. The K2 stores its frequency information in EEPROM and retrieves that info during operation. The only time an accurate frequency reference would be a benefit to the K2 is during the dial calibration steps of adjusting

Great news, I have been waiting for this option ever since my K3 arrived. The method implies the phase noise of the 10MHz reference is not so important - which is useful to know. My high spec reference is 5MHz and my cheap one 10MHz. The 10MHz will have worse phase noise than the TCXO in the K3

Any news on the External Reference Option ? 73 Trevor G0KTN Original Message from Wayne N6KR dated 14 June 2010 There appears to be more demand for this than we thought, so we're looking into it again. Note that our planned external reference implementation would not req
