Update: Yaesu back on the air

Citizen Jed helped me find an Elmer willing to do the surface-mount work on my Yaesu. After some email exchanges, he inspired me to go back through the relevant circuits, and that reminded me of some work I had done in the power supply.  It had developed an intermittent between the transformer and the rectifier.

The power supply was not putting out DC.  When I went back in, I found that joint had broken again. 

I cleaned up some soldering on the aftermarket RC battery pack also. 

We're back in business.
