DTMF Radio Record Simplex Repeater Controller SR-112

The SR-112 is a multi-function voice recorder device that connects to virtually any handheld, base, or mobile radio. It features exceptional voice recording quality and higher capacity than any other comparable device on the market. Simplex Repeater: A simplex repeater records incoming transmissions and retransmits them on the same frequency. This has the effect of doubling the time required to transmit a message, but while a traditional repeater typically costs thousands of dollars and might be semi-portable at best, a simplex repeater can be set up with a single handheld radio and operated from batteries. This makes it perfect for disaster response, home or campground use, and any place where radio range needs to be extended but the cost and complexity of a traditional repeater can't be justified.
