If the TM-1 is connected to a computer running the Configuration Program, then the programs "TM-1 Status" display should change from "Disconnected" to "Connected" after a few seconds.
RECOMMENDED PATH: Throughout North America (and in many other regions) the recommended path for Mobiles or portable stations is now WIDE1-1,WIDE2-1. Fixed Stations (Homes, etc.) should normally use plain WIDE2-2 or less. This new protocol has caused the RELAY, WIDE path to become obsolete.

Recommended Path Settings for MOBILEs in North America, at least (VHF)


  • WIDE1-1,WIDE2-1 :Two hops in all directions and potential for fill-in digis. Best path for mobile use in most all areas.
  • WIDE1-1,WIDE2-2 :Three hops and potential for fill-in digis. Use only while needed if far from any mountain digis or cities.

Recommended Path Settings for FIXED stations in North America, at least (VHF)


  • WIDE2-2 :Two hops, recommended max courteous routine for most areas. Best routine from home in most areas.
  • WIDE3-3 :Three hops, only for very sparse areas far from any mountain digis or cities. Limited to one hop by many digis.
