Reply to "ZW-C Problem"

Well, I am as far from an expert as you can get. But I am a long time ham radio guy and have worked on vintage ham gear for 25 years. It's a very different animal from what we are dealing with today on a layout with modern electronics. So whatever experience I have may be worth exactly what you are paying for it--nothing! But here is what I would say about your readings: Fine, good, no problem. Your readings are well within the tolerances of the components and gear you are using. Please proceed to run your trains and enjoy them. 

The subtext for me is that electronics is not as exact a science as the engineers would have us believe. Just because your meters will indicate down to 1/10th of a volt doesn't mean that makes any difference to the operation of your equipment. It RARELY does. I know nothing about modern digital electronics and the very idea that an oscilloscope will show waveforms up into the Ghz region astounds me. But my daily hobby work has no use for that level of exactitude, nor indeed do I have any signals in the Ghz region to measure! 

So my free advice (again disclaimer, worth every penny you are payng....) is to ignore your voltage variations and go ahead with what you were doing. All will almost certainly be well.
