What radio can do that? And what is the master oscillator consist of-
does it contain a cesium/rubidium stage?- Hide quoted text -

I keep wondering how you'd measure such a thing. *Leave it on for
several years to see if the oscillator drifts one hertz?


It might drift more that a hertz over that extended time frame,
I'm too impatient to see.
Usually check it about every other month on a boring Sunday.

Not to be too precious, but that does not sound like the best use of
one's hobby dollar to me ;-)


I don't dwell on stability to the point of obsession,
It's just one of many assets the radio has going for it.
And the hobby dollar cost, once made, is better justified
for the totality of features than any single one.
At least I'm not constantly pouring cash into the black hole of some other
hobbies. I used to be heavily into film photography g

I can't think of a good one that is.

Mine a

Guns.
PCs.
Ham and SW radio
Hifi
Cars.
Dogs.

And sooner or later, I'll be biting on an RC truck or helicopter, it's
just a matter of time. I'll go out with the friend who is into all that,
and I get hooked again. About 20 years ago, I got into it pretty heavy,
but the constant wrecking of the car I had got to be ridiculous.
They have some trucks and buggies now, electric ones, that go well over
60 MPH, and if you have the $$, you can go over 80.

If you fly, and have insane money, you can get yourself something like
these, and really fly:
