Reception integrity should be greater than 90%. If reception integrity is lower
than 90% suspect a damaged antenna. If the antenna is known to be good,
suspect a failed radio. Swap in a known good radio, and retest. If integrity is

setup. For example, is the rover within line of sight of the base or repeater?
