Although the regulators within the unit are designed to run within spec, I like to keep temperatures down. Lower temperatures increase reliability in the longer term. This pic shows a modification to lower the temperature of the EZKit(Digital Signal Processor) regulators
A length of ali bar 1/2" by 1/4" was fitted between one regulator and the outer case
A further piece of ali bar was drilled and tapped to get the heat from the other regulator to the top of the EZKit box, and the box lid is now 1/16" ali sheet instead of FR4 material to further help conduction.
Overall it just gets pleasantly warm to the touch rather than about 45 deg as previously.
Another thought: So I can change over from internal 10MHz to external frequency reference I am going to fit a small 5V relay by the connector - this will be operated by a rear panel switch.
