Out past the last cell tower, “comms” stops being an app and turns back into seamanship. The gear’s only half the story; the rest is where you mount it, how you feed it clean power, and what you do when salt, vibration, and an overdue crimp decide to have their say.
I’ve seen fine radios made mute by a tired battery, a green connector, or one clever splitter that became a single point of failure. If you build your communications like you build your ground tackle—layers, backups, and a bit of suspicion—you’ll sleep better and waste less time talking to yourself.
