The wires-x in the diagram above are three DR-2X C4FM repeaters. The repeaters are located in Cleburne, Mansfield (WIP) and Palmer Texas. They are linked together via WIRES-X (Texas-MRN / 04971). In addition, the WIRES-X room is bridged to an XLX reflector that is connected to the MRN network. The MRN system is fully integrated. This means, when one access point listed above receives a signal (transmission), all the other access points will repeat the same transmission. This includes both analog and digital protocols.
The DR-2X repeaters will automatically (AMS) work with both digital and analog signals. That means the repeater will function with either analog FM signals or digital C4FM signals. Whatever it hears, that is what it repeats. So, if you have a good old-fashioned FM radio, it will work perfectly fine. The beauty of the Fusion system is that if you have a Yaesu digital radio, your radio will coordinate with the repeater and will automatically switch between analog and digital. So, with your Yaesu digital radio, you can also talk to ordinary analog FM stations as well as digital. This is as close as it comes to universal compatibility between digital and analog modes of operation.
MRN tip: When using the DR-2X repeaters, the mode will need to be voice wide (VW) in order for the traffic to be received across the MRN network. The other modes (ie. FM; VW) that are available on the DR-2X repeaters will only be heard locally via RF. Voice Wide (VW) mode is unique for the MRN. Most networks will use digital narrow (DN)
