Sadly no time last night for anything particularly scientific, but having observed temperatures about a dozen times last night and again this morning it looks like this:
Condx = 7.3v supply, in diecast box, in outer box, NO beads, sitting on rack.
probe temp holds at around 7C higher than ambient temp.
As the room temp in here varies between 23 - 26C depending on if lights and monitors are on - the resulting swing on the after an hour or so from power on is 30.4 - 33.8 (from observation).
Heating appears to be significantly less than with a 12v supply.
What I plan to do now is:
a) cut a polystyrene block to fit around the xtal inside the diecast box to reduce temperature changes inside the box from any convection etc
b) re-add the beads to provide thermal insulation from room changes.
..... Oh... and try and get a wire antenna up today :)
