W3PGA Repeater Shutdown Controller
Our repeater shutdown board. Our control link is on 70 CM simplex. The HT is a Kenwood set to our control frequency the audio is fed to the DTMF decoder board. The green pc board is an 8 channel DTMF decoder and relay unit. The smaller board above is the relay circuit for 2m and 70 CM relays to shutdown each repeater individualy with the proper DTMF Code. Once the proper code is received for a band the relay system switches the AC Off hence shutting down the Repeater. The proper code sent turns it back on. There are different codes for each repeater.
Our battery backup will run both repeaters for approx 24 hours.
