Universal HAMrepeater controller.
Based on STM32 bluepill adrduino board. It basically connects two base VHF or UHF radios.
Controller makes a 3 second TX tail with short beep in the end after each transmition, to understand that repeater is available, and message forwarded. Every 15 minutes Controller sends on air CALLSIGN of repeater or QTH locator by morse code. Schematics https://github.com/diygoodies/REPControll/blob/master/Schematics/REPControll.pdf
