As some stated how simple you look'n for. Get input key transmitter well simple COS driving a NPN transistor for PTT and it is repeatering. Common on commerical, but not enough for ham use.
If using CTCSS then often the decoder output can be used for this for some have open collector low current outputs that can be used for this. If you want ID, remote control, timeout, tail timer, audio shaping, etc well might still be simple, but will require more. One good item to look for the Micor repeater "Squelch Gate" card. This will take rx discrementor audio, trip when the adjusted level of quiting is found and has ptt output. I think it has the proper de- emphasing audio circuit. Again how simple. 73, ron, n9ee/r --- In [email protected], "shame_you_promise" <[EMAIL PROTECTED]> wrote: > > hi im thus anybody here who knows on how to build a very simple > repeater controller with-out any programming just a verry simple > repeater controller...and also how to connect the two radio.... tnx... >
