[ARC5] TCS 50-Ohm Matching Configurations.

[Tim]

Could the TCS output network components and various antenna/load
combinations be modeled with SPICE?  Then various interface networks be
tested and optimized for max power transfer/efficiency?  Been a  long time
since I could do that, and I no longer have access to the software.

I think the "solution" is in the math...no?
