Re: John and Mike
"Thanks." John rubbed uncomfortably at the back of his neck. He didn't like thinking of his mother being dead. She'd been his world for most of his life, except for those three years she was in confinement. But, he knew he had to face that possibility and just prepare himself to do what she'd given her life to raise him toward.
Leaning against the wall, he crossed his arms while he thought about using radios as the switch. "It could work. We'd only need a handful of multi-channel handsets to take with us, one for each house. Get a number of smaller receptors for the actual triggers. It's not that hard to reprogram them to enough different channels with enough space between we're not accidentally detonating the explosives for the house next door." It wasn't as elegant as the more computerized options he could program into the phones. But, Westen had a good point about the possibility of jammers.
"We could set them up on timers," he suggested. "If we reverse them like you suggest, we only need to wait until each unit is far enough from the outermost blast zone. Set all the layers for a given house to the same frequency, but only one triggers an immediate explosion. Set up simple watch timers for the other layers at separate intervals. As long as they're somewhere within the blastzones, it doesn't matter if they're caught by the first, second or third layer. At worst, they get separated by the blasts. At best, we blow them to hell along with the houses and evidence.
"No, thanks." He raised his mostly untouched soda. "I'm fine for right now. If I don't go back out soon and get some of the barbeque, Savannah may barbeque me," he added with a chuckle.
