Enclosure
MoonLanding • 04/29/2015 at 23:08 • 0 comments

Purchased on Ebay a nice extruded aluminum enclosure, and mounted the (also ebay) ISOTEMP OCXO (10MHz). The mounting is free-floating: simply foam surrounding the crystal - tight enough for it to not shift or move around. Foam is glued to the enclosure with Gorilla PU style glue.

You probably already found this, but a quick google led me to this: http://www.isotemp.com/wp-content/uploads/2011/06/Legacy134-10.pdf

The really good news is that this appears to be voltage-trimmable OCXO, meaning that you could turn it into a GPSDO if you wanted.

Are you sure? yes | no
