Hi I am working on a project to interface an allstar node on a multimode digital repeater based on the MMDVM This would woould create a multimode fm,dtsar,fusion and dmr repeater system. I know some people dont like that. but on a remote site where energy and antenna deployement difficult and for place where installing multiple repeater is price prohibitive, this is a nice solution. No mode is left aside. but only one can be used at once. So in order to make this work I need to know how the cop 2 and 3 command works. I want to use the event manager to send those 2 command when one input from my URI is switching state. this will be connected to the MMDVM and it will prevent the tx or false rx when the DVMDM is taking control of the repeater. WHat happen to any audio received by the network when in disable mode? IS it still present at the URI? Does the link that are present stay connected or they disconnect? I need this so that I can figure out if it is more effective to use a pair of small relay to cut the audio lines and ptt lines when the MMDVM is active or doing it by software. thanks Pierre VE2PF
