Box for the voltage reference circuit

Nothing special.... just boxing some stuff, here's the voltage reference IC in a box.

The board is very small and it could be lost in the shack mess so I used one IF transformer box from an old Bendix ARDF equipment for housing.

Regarding the voltage reference, it's not a voltage cell but for the nature of my measurements and calibration it's more than enough, my DVM doesn't have enough digits for measuring to the millivolt unit.

Maybe one day I could get a better DVM...
