[ARC5] Oscillator Stability and Old-Time gear. (Was OT: Hally Instability)

[Dennis Monticelli]

Glen,

Not only would your suggestion result in a better appreciation of just how
far the state-of-the-art has progressed, it would develop an appreciation
of how much op skill mattered in terms of having successful QSOs.  6 mo of
old school "training" would make them into better ops.
