[sdiy] Semi OT.. Toyocom TCO,scillator!

[karl dalen]

If you open up a typical canned TCO crystal, inside
soldered onto the ceramic substrate is a chip
6532a (i asume is a crystal driver) but are TCO's
temperature compensated by such a chip by varicap!
yes/no?

Or have i mixed it up with TCXO,s?
(VCOs, OCXOs, VCXOs, TCXOs, VCTCXOs, DROs, many to chose from).

I had the idea to heat up the TCO to get a better PPM from it!
Isnt actually so that a TCO without x init is simply a plain
un temp compensated crystal with its driver?
