TX Debug Steps?

W8SWG
 

I have been running my uBitX very successfully using WSJT-X for about a week and now all of a sudden I cannot make any contacts at all.  I am still receiving perfectly I do not seem to be getting out even with close contacts.  The indicator says that it is transmitting and the heat sinks warm up but still no contact.

I am a noob and have almost nothing in test equipment except for a VOM.  Anyone have any suggestions?
