I re soldered the entire board (the pins that plug into the radio were bad too) and it now works fine. A couple of the crystal pins would not reflow and I had to remove the solder and put a small wire around the crystal pin and connect to the foil to get them to resolder.

When the unit is plugged into its slot (on a Corsair) we get no response. Our next step is to test it on a network analyzer but I felt it would be worthwhile to also get inputs from people on the reflector.
