      It should most likely be WIDE1-1,WIDE2-1. As it is, only the WIDE1-1 is
      having any effect and the 1-2 is just an extra 7 bytes (each path
      component is 7 bytes, regardless of actual values) in your packet header.

Unfortunately the the Manual for T2 assumes that everyone understands what all the commands do. Unfortunately only having been messing with APRS for around three months this is not true for me with some of the more obscure commands. Thanks to one and all. Keep up the good work. 73.
