I would like to install one in my new K3, but as far as I can tell, it is not yet being offered for sale.
I have long had an interest in the precise measurement of time and frequency, and have several 10 MHz reference oscillators. (The only time that I participated in the ARRL FMT, I was limited by ionospheric doppler, making a better measurement on the West Coast station than from W1AW on the east coast.) 73, Jim K7KK Saint Helens, Oregon, USA "Remember, Ignorance is the Mother of Adventure!" -- Hagar the Horrible ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
