Cecil, One thing at a time. The static test with a DVM was quick enough to prove that one should not be using the internal DC measurement as an accurate indication of anything truly vital, other than to say that there is a voltage present from the power supply. The O-Scope test is a little more involved, thus is being saved for this weekend. I will be using a digital storage scope so that I may capture a bit of data. This horse only drinks on the weekends ;) Thank you, Mike W5CUL

You need a better power supply or a lot of work on cleaning that one up. I keep mentioning that to test the power supply you need a dynamic test not a steady state test because how the power supply reacts to change can be many times worse than the wiring drop, but it seems that the people testing are bent on doing static test which are rather useless in the long run. Forget DVM's they are too slow to see what is going on you need an oscilloscope. You can take a horse to water but .....
