How does the FCC define a repeater?.
A repeater station is an amateur station that simultaneously retransmits the transmission of another amateur station on a different channel or channels [97.3(a)(39)]. Only repeaters, some types of auxiliary stations, and space stations may automatically retransmit the radio signals of other amateur stations [97.113(f)]. Holding your mic in front of the loudspeaker of a receiver so you can retransit the signals of another station is not “automatic,” so this is not “repeater” operation.
