[time-nuts] Power Supply Questions
Does the power source for just a GPS module matter that much? Most that I've seen just use a cheap wallwort and a lm-whatever 5v regulator chip... nothing fancy. My second question is what do you guys think about Acopian power supplies? I picked up a couple 24v linear gold box models with good regulation and low ripple for super cheap on eBay (model A24MT210 if you want to look it up). I figure it has to be better for my GPSDO than the cheap switching PSU I have been using.

Jason Wall warts do (as other supplies with high transformer primary secondary capacitance) have the unfortunate capability of coupling high amplitude transients on the mains from the primary to the secondary. The cure is simple: a non polar capacitor with an appropriate value (several hundred nF to 1uF or so) connected across the secondary - often omitted to save money. An AC traszorb connected across the secondary can also be used.
