Well looks like the soldering approach is not going to work. Before you 
jump all over me please note that I am very good at that sort of thing. 
I even went so far as to remove the old solder, etc. I've traced out 
really all I can do with my limited test equipment. So guess it is to 
Ten-Tec. I suppose they will want me to send the entire transceiver and 
not just the two boards?

Sad way to start the new year. :(

Thanks to all for their suggestions.
