You can also put the NHRC2 repeater controller in Simplex mode.
If you have the ISD sound chip installed, when the controller is in simplex
mode it will record the last 20 seconds of audio, then when the carrier is
gone, it will key the transmitter and replay it.

of their simplex repeater was to fill local coverage holes. The

Good Day,
We are using simplex radio (using single frequency for transmit and
receive) and we would like to build a repeater. We would appreciate it

The RS, as others have suggested, did just as you want and yes they
have not made them for a number of years. Every once in a while do
see on ebay.
I've used a version of the ISD voice R/P IC for similar

ISD14xx series
