Minima VFO - Under the Microscope

I have been doing some troubleshooting of my Minima VFO, for some reason it is not "talking" with my Minima CPU module. My friend Jeff - KO7M as provided some suggestions for resolution that I am working on.

Just for fun, I took some Microscope Photos while reviewing the circuit and PCB layout for errors. Here are a few for your review.

The 3.3 Volt Regulator - SOT-89-3
and Its Output 0805 Filter Caps

Power Indicator with its attending limiting Resistor
The Resistor and LED are size 0603

I enjoy working under the Microscope, there are many things that otherwise we would not see.
