What is Ham Radio Freedom? They share benefits of digital radio communications in providing increased range, improved sound quality and advanced security capabilities. In such a system, when one repeater is keyed-up by receiving a signal, all the other repeaters in the network are also activated and will transmit the same signal.

Many repeaters are located on hilltops or on tall buildings as the higher location increases their coverage area, sometimes referred to as the radio horizonor "footprint". LID refers to a poor operator radio methods usually from improper training from other Amateurs or exposure to different types of operation such as CB radio.

Amateur radio repeater
Repeating signals across widely separated frequency bands allows for simple filters to be used to allow one antenna to be used for both transmit and receive at the same time. They share benefits of digital radio communications in providing increased range, improved sound quality and advanced security capabilities. This avoids the use of complex duplexers to achieve the required rejection for same band repeating. Mixed-Mode Kenwood DMR repeaters can be configured to operate in Mixed-Mode which allows the repeater to switch automatically between analogue and digital, depending on what signal has been received.
