If you read my original post again or at least the topic, it says 0-12 (not
0, 12) MHz. And that would mean something in the range between 0 and 12. I
don't remember when and WHERE i said that i need 0 MHz oscilator. The only
one who talks about 0 MHz osc is you.

Perhaps English is a second language for you, but when you say 0-12 that
will be taken to mean those two frequencies and everything in between.

And of course, even if such a full range oscillator was not intended
by the original poster, I'd say there often is a big difference between
oscillators in the KHz range and those in the MHz range. Obviously,
the concept of an oscillator doesn't change, but the specific design
does.

You can use resistors and capacitors to set the frequency down near
the audio range, and do your best to avoid coils down there due
to their size, while once you get into radio frequencies, one tends to
use coils for the frequency control element.

Time after time, I see people asking questions about oscillators,
and often they are coming to radio frequencies from an audio background.
So they think in terms of just scaling some favorite audio oscillator
up to radio frequencies, when a simpler solution would be to use an LC
oscillator.

Somewhere in this thread, the 8038's more recent spawn was mentioned.
Obviously, it will work over that full range, but I'm suspicious about
how good it will be at radio frequencies, as I would about any RC
oscillator. It seems a stretch to expect it to work as well at 12MHz
as at 10KHz.
