A team working together can accomplish a Radio Coverage Survey Session in a series of one-and-a-half to two-hour periods. These short sessions enable more volunteers to participate and may be scheduled any time or day of the week. | A team working together can accomplish a Radio Coverage Survey Session in a series of one-and-a-half to two-hour periods.

PBEM recommends that rover team survey locations should be selected to form a uniform grid across the NET Service Area. A uniform grid is most easily constructed in areas where streets are arranged in a uniform rectilinear pattern. In this situation, survey locations may be places at street intersections. Where long blocks break up a uniform pattern of intersections, survey locations may be placed at specific addresses. | PBEM recommends that rover team survey locations should be selected to form a uniform grid across the NET Service Area.

In areas where streets follow elevation contour lines, survey locations may also be placed at specific street addresses or other easily identifiable locations. These locations may be where streets change directions, traverse abrupt changes in terrain, or pass by a distinguishing landmark. | |||
The distance between survey locations should be short enough to eliminate ambiguity in the radio voice quality values in a region. In general, in NET Service Areas with relativity flat terrain, survey locations may be spaced further apart than in areas where elevation changes may obstruct radio signals. Some experimentation may be required to determine the best distance between survey locations. The distance between survey locations may differ in different parts of a NET Service Area. | |||
Taking measurements at too many locations is more advisable than skipping locations and introducing uncertainty into the results. | |||
=== Survey Command Post === | |||
The Survey Command Post should be located at the Primary Incident Command Post as specified in the NET Operations Plan. However, Radio Coverage Surveys may be used to evaluate the suitability of other locations if the Primary Incident Command Post has not been established or is being evaluated for relocation. | |||
The Command Post should be staffed with at least two participants: one person acts as the Survey Radio Operator (SRO), and the other acts as a Scribe. The SRO and Scribe collaborate to decide on a Radio Voice Quality Value and other Rover Team information being recorded on the Command/Listening Post Log form by the SRO. The Scribe complete a separate log form to help collaborate on the information received. The Scribe may also check off each reported Survey Location on a copy of the reporting team’s Survey Area Map. The SRO’s log form should be considered to be the official record and the Scribe’s copy as an aid. | |||
During initial sessions, it is preferable to have the Team’s Amateur Radio Operator (ARO) be the SRO. The ARO should brief participants on effective radio protocol. Other participants should act as the SRO during later sessions to gain experience in the Incident Command Post Neighborhood Radio Operator (NRO) role. If the workload overwhelms the ARO, the NRO role may be established. The NRO would be responsible for all NET FRS/GMRS communication in the Service Area. | |||
