Okay, here’s a quick three‑phase plan, and I’ll try not to lose track of the deadlines this time: Phase one – rummage through the backroom and pull out every crystal set, ferrite core, and that dusty old radio transformer we never used; phase two – wire the crystals into the fort’s existing power rails, solder those loose connections, and mount a small, low‑power crystal oscillator on the command console; phase three – crank up the transmitter, run a quick loop‑back test to check latency, tweak the crystal tuning, and if everything stays quiet, we’ve got a solid perimeter signal. Just remember to double‑check the power rating, or those crystals will go out of whack faster than a busted clockwork.
