No I had not and that solved the problem. Thank you! The README.md file I found in the Arduino library said this about that #define and so I assumed it would default to Serial:

_The remaining variables are rarely used, but we list them here for completeness._

_#### Changing debug output_

_`#define LMIC_PRINTF_TO SerialLikeObject`_

_This variable should be set to the name of a `Serial`-like object, used for printing messages. If not defined, `Serial`_  
_is assumed._
