Building my first serious go-kit for ARES deployments and looking for input on what's actually essential vs nice-to-have. A go kit is a portable, self-contained communication system designed for rapid deployment during emergencies, disasters, or field operations. When power is lost, cellular networks fail, or communication systems become overloaded, a properly prepared go kit allows you to establish reliable radio contact immediately. So far I've got a Yaesu FT-891, LiFePO4 battery pack, and basic hand tools. What am I missing that could bite me in a real deployment?

Missing small components can prevent communication entirely, so a complete packing list is essential. Radio equipment should include your primary transceiver, a backup handheld radio, microphone or headset, programming cable, and spare fuses. Don't forget coax adapters and a basic antenna analyzer if you can swing it - field antenna work always throws curveballs.

Use pouches—radios in one, power in another—for quick deployment. Seal electronics in zip-lock bags; test for water resistance per IPX4 standards if applicable. Also learned the hard way to include a headlamp with red filters - you'll be working in the dark more than you think!

One thing that saved me during Harvey - an inventory of the kit. Laminate a checklist and tape it inside the lid. When you're stressed and tired, you'll forget what you packed. Also consider tape and tools, spare batteries, headphones, flashlights of some sort, cell phone chargers, and a multimeter. Other items that won't fit in a bag but may be needed include a generator, a working surface like a small folding table, a chair, and some type of shelter.
