There are lots of ways you can unintentionally affect a device like an LPRO. For instance, suppose the internal power supply dissipates a different amount of heat depending on the input supply voltage. This could cause the oven to momentarily shift its internal temperature a small amount... which may show up as a frequency shift. Or suppose the current change due to changing input voltage causes a magnetic disturbance that shifts frequency?
We're time-nuts. We are trying to get more from these devices than the manufacturer ever intended. -Chuck Harris Marco IK1ODO -2 wrote:
Eric, the power supply quality is not critical. The LPRO (like most other Rb's) has an internal switching power supply, so the wide tolerance in the primary power source voltage. I found other Rb's to be quite sensitive to vibrations, but when they are in a box, with a decent PS (I use an universal portable PC PS, the variety that may be programmed by means of a resistor in a plug) and an heat sink they are happy.
