There's a cosntruction article by K2AOP on page 67 for a xtal osc that
sounds appealing to me. ARRL says it couldn't measure the phase noise
because its lower than their equipment. I wish they would have stated how
low their eqpt goes as I was lead to believe they had some of the best.
Anyone have any ideas?
tnx

They can usually get down to -160, -165 dBc/Hz depending on which cheek they
hold their tongue in. I now wish, they'd get me my copy here. Don't often
see a construction article in the rag. Do they take the output from the
crystal using it as the "final" filter?

I always thought I was last on the QST delivery line. It says its a Pierce
with a gate follower buffer for output. Quite stable and constant output!
It uses 2 2N5460s. I need to find a half dozen 2N5460s so I can build at
least a couple to test receivers.. If someone finds a source please let me
know. Also it someone builds and measures the phase noise please let us
know.
tnx

Mousser has them, although they seem to be a very ordinary P channel FET.

Would 2n5461's work. IIRC they are basicly the same fet, different IDSS
maybe.

Digi has them as well, and I have some on order. Doubt there are any
surprises, but hope springs eternal. Suspect that the "Tech Correspondence"
dept didn't have the clout to get the attention of the lab. Will let you
know in about a week.
