So, if I take my nice clean 10 MHz, rig up a counter that counts to
25,000, and a suitable PROM and DAC... (or run a DDS chip)... I think
that would be a "clean and stable" 400 Hz.
Of course, for the more mechanically inclined.. what about a big
flywheel driving an alternator. You might be able to rejigger a car
alternator. I don't recall how many poles they have..you might have to
spin it pretty fast.
