Again, I just read it somewhere on here, that may have been posted from a few years back. I’m not on here enough to read enough through outdated posts. So again, before ordering double check to see if this LINKED SYSTEM is accepting SIMPLEX. That’s all I really know, I just own duplexed repeaters, never played with SIMPLEX repeater systems, other than peer to peer and group communications. Don’t Quote Me on RULES lol, I’m NOT up to date yet! Good Luck[emoji1303]
