I dont know how much accuracy you need, but if no more than 1 ppm or so, find a Leader 823s frequency counter (S model is 1 ppm) cheap on ebay. Its internal clock is 10 mHz and it will put that signal out via a back panel BNC. You can zero beat it to WWV first to get it within a few Hertz or better. Mine holds to much better than .5 ppm.
Other counters may have the same, I dont kniw, but this works for me.
