The interesting thing about the Miller example is that if you click on the link that goes to his page, the OCXO that he shows is just a simple, cheap Temex(?) part. I bought 5 or 6 of these, or something that looks very much like them, for about $20 each not long ago from a UK seller. Nothing special about it. Tom, was this graph taken with his Isotemp 10.0 MHz OCXO, or the cheaper one? What was your reference... one of the masers? -- john, KE5FX _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
