What is a “simplex repeater?
A “simplex repeater” is used to extend the range of low power rigs such as handhelds by storing the signal transmitted on a frequency and then retransmitting it through a more powerful or better-situated transmitter on the same frequency. According to the rules, however, such a device is not a repeater since it does not simultaneously retransmit the signals of another station and it does not retransmit the signals on a different channel or channels, as specified in the FCC’s definition of a repeater, so it can’t be operated under automatic control. If a control operator is present and controlling the device, either locally or by remote control, then it can be used. But it cannot be left unattended! On the other hand, it is not limited by the other repeater rules, such as repeater frequencies.
