Congrats to Glenn, who wired up a perfect "Backup Pyrotechnic System" board!
We now have a working 2m radio receiver board which sends audio to a Holtek HT9172 DTMF decoder that in turn feeds into an Atmel ATMega168 microcontroller. I just finished the firmware, and I've got it responding to our usual DTMF command set: arm, disarm, blow pyro 1, blow pyro 2. I've tested it as much as I can - we'll do more testing tomorrow.
