On the same page, look for "Link to Map of NCSHP Troop layout" and click on the link to show the troop layout. Download the map for future reference because listed on that map are the old (but still in partial use) conventional system frequencies. Just match the color of the counties in your troop section to the color chart in the lower left corner. The "station" frequency is station to car and the other frequency is car back to station. You will need both frequencies for the full communication.
