I absolutely love my XG3 and have not even begun to exhaust the list of uses for it.... Reference signal source is NOT on the list.... I have had the priviledge of working with half a dozen XG3s at one time... They are not even CLOSE to precision frequency references.... often varying anywhere from 0 to 30Hz from the programmed frequency.... Of course, that is NOT their purpose....
On the other hand, using the 20 or yes, the 25 MHz signal from WWV, I can get sub 1Hz accuracy when zero beating my K3S. I happen to be fortunate to own frequency counters, external references, et al instruments to get BOTH precise frequency, and AT LEAST equally important, precise TIME syncs.... The VAST majority of filks do not.... If you only have an XG3 then you fall in that vast majority too. WWV is essential to national infrastructure. When the grid goes down and the cell towers go dark.... or the military flips the switch on the satellites, WWV should ALWAYS be there to keep the system running. 73,Clay, KY5G Sent from my Verizon, Samsung Galaxy smartphone -------- Original message --------From: Charlie T <pin...@erols.com> Date: 8/20/18 11:45 (GMT-06:00) To: elecraft@mailman.qth.net Subject: Re: [Elecraft] WWV/WWVH Closure Yeah, I'd miss them, BUT, my little Elecraft hand-held XG3 sig gen is pretty handy for that too . Also, I don't believe funding for the 60kHz sig was ever at risk and THAT's what your (antique) watch uses. 73, Charlie k3ICH -----Original Message----- From: elecraft-boun...@mailman.qth.net <elecraft-boun...@mailman.qth.net> On Behalf Of Wayne Burdick Sent: Monday, August 20, 2018 11:53 AM To: Elecraft Reflector <elecraft@mailman.qth.net> Subject: Re: [Elecraft] WWV/WWVH Closure Personal note.... Ever since I home-brewed my first receiver when I was 15, I've used WWV at multiple frequencies as a source of reliable on-air test signals. My early receivers used simple direct-conversion schemes based on JFETs (remember the MPF102?). Get the details wrong, and you'd hear WWV whether you were tuned to it or not, thanks to what I now know was IP2 (AM breakthrough). Do it right, and you'd be rewarded with those undulating time-tones: minimalist, almost musical. Something Phillip Glass would pipe into his sensory-deprevation tank. Oh, and you could set your watch to it. These days I still tune into WWV to check VFO calibration, set clocks in the field, and get an approximation of the MUF (Maximum usable frequency). When propagation is good, even the 20.000000 MHz signal soars across the aether, a faithful and tireless chronological savant. Losing it would be a tragedy, but a nerdy one, not Greek.
