Neighborhood Teams to Neighborhood Leaders (and Neighborhood Leaders
to Section Leaders)

Communications between Neighborhood Teams and the Neighborhood Leader, and if a Section is established, between Neighborhood Leaders and Section Leaders, should use Family Radio Service (FRS) or General Mobile Radio Service (GMRS) radios owned by the individual team members.

FRS Radios are low powered UHF radios with a “line of sight” range. GMRS Radios have slightly higher power, but generally require line of sight. If you have difficulty contacting your Neighborhood Leader, try moving to higher ground or at least to a different location. Moving as little as 6 ft may make a dramatic difference in signal clarity.
