Depends on a few things... do you want the repeater to key on received voice/speaker volume level detection or from a logic level change like a carrier squelch or CTCSS (PL) detection logic?
Voice audio detection can work OK if you consider the key up delay in the repeat path, but using two voice triggered circuits each direction for a bi-directional repeater doesn't work so well. s. > "gervais" <ve2...@...> wrote: > > Hi all > i am looking a COR board that i could use between 2 walkie-talkie that would > be used here as a replacement for my regular repeater in case of accident. > i have seen this many years ago,an amateur built his own repeater with 2 > talkie's,simple and efficient. > So maybe someone know where i could find such a board,,,controler what ever > you call it,no need for queue,,,just a simple repeater. > > thanks > Gervais ve2ckn >
