Interesting writeup!

Today I learned about TCXO.

If anyone else are curious, that component cost about $2 per piece.

Yea! Useful if you need precise timing under temp swings. I use them for UAS LoRa radios. Def more expensive than a normal XO!

It's also something you want to look for if you're buying an SDR. Getting one with a TCXO will eliminate frequency drift, and the better-made SDRs will also have little or no need for frequency correction.

But cheaper than OCXO and far less power consumption too. Also (much) less stable.

Compensating for the temperature will never be as accurate as actually controlling it (O is for ovenized). I keep reading about chip scale atomic clocks coming down in price but I've yet to see them as the oscillator in anything mass produced.

When 2G started being decommissioned ebay was suddenly flooded with super cheap rubidium frequency standards from parted out base stations.

I'd love to have some.

Also cheap OCXOs.
