Ham Radio for Preppers: Why It's the Foundation

Why Everything Else Fails

In a significant emergency, communication infrastructure fails in a predictable sequence:

Cell networks: Overloaded within minutes of a major event. Cell towers lose power within hours unless on emergency generators. The 2011 Japan earthquake and tsunami knocked out 14,000 cell towers. After Hurricane Katrina, the Gulf Coast had essentially no cell service for days.

Internet: Depends on cell towers, cable infrastructure, and data centers with generator backup. Goes down as cell networks fail. Also dependent on ISP infrastructure that may be physically destroyed.

Commercial radio stations: Typically small-staffed, generator-backed, may evacuate and leave automated emergency broadcast running. Receive-only for listeners — no way to transmit your situation.

Landlines: More robust than cell, but most homes no longer have them. Those that do depend on telephone company infrastructure that may also be damaged.

FRS/GMRS/MURS walkie-talkies: Limited range (0.5-5 miles), cannot reach emergency services or distant family, no repeater infrastructure.

Ham radio is different because it's decentralized. Your antenna and radio are your infrastructure. You don't need a working cell tower, a data center, or anyone else's equipment.

What Ham Radio Provides

Local communication (VHF/UHF — Technician license): A handheld radio (HT) with a nearby repeater can reach 10-100 miles. Repeaters are typically on high ground with emergency power backup. Many are activated specifically for emergency communication. You can:

• Reach local emergency nets
• Communicate with family members if they also have HTs programmed with the same repeaters
• Check in with neighborhood nets to coordinate local mutual aid
• Receive and relay information to those without radio access

Regional and national communication (HF — General license): HF (high-frequency) radio bounces signals off the ionosphere, allowing communication at distances of hundreds to thousands of miles without any infrastructure. You can:

• Communicate with family in other states directly
• Reach distant emergency nets
• Receive international news and status information
• Participate in Winlink (email via radio) and other digital modes
• Contact anyone worldwide who is listening on the calling frequency

Emergency networks: ARES (Amateur Radio Emergency Service) and RACES (Radio Amateur Civil Emergency Service) are nationwide organizations of licensed hams trained specifically for emergency communication. After every major disaster in the US, ARES teams are activated and serve as the communication backbone for relief organizations, hospitals, and emergency management when conventional systems are down.

Being licensed and participating in ARES gives you a trained team to connect with, practice opportunities, and integration with official emergency management.

What You Need to Get Started

The minimum kit:

1. License — Technician class. Study free at hamstudy.org. Exam fee ~$15 from volunteer examiners (VEs). Takes most people 10-20 hours of study.

2. Handheld radio (HT) — A handheld VHF/UHF transceiver for local communication.

   • Budget: Baofeng UV-5R ($25-30, capable but poor quality)
   • Better entry: Yaesu FT-60R ($120-130, mil-spec durability)
   • Dual-band standard: Kenwood TH-D74A ($500, full featured with APRS, excellent receiver)

3. Programming — Radios need to be programmed with local repeater frequencies. CHIRP is free software that handles most radio models. radioreference.com has your local repeater lists. See the CHIRP programming article.

4. Basic antenna — The rubber "duck" antenna included with HTs is marginal. A replacement antenna (NMO or SMA connector depending on your radio) improves range significantly. The Diamond SRH77CA ($15-20) is a standard upgrade.

The complete budget kit:

• UV-5R: $25
• License: $15
• CHIRP programming (free) with local repeaters loaded
• Replacement antenna: $15
• Total: $55

A serious starter kit:

• Yaesu FT-60R: $130
• License: $15
• Programming cable + CHIRP: $10
• Nagoya NA-701 antenna: $15
• AA battery case (backup power): $8
• Total: $178

Frequency Fundamentals

2 meters (144-148 MHz): The primary VHF band for local emergency communication. Most repeaters, APRS, and local nets operate here. Your HT is likely 2-meter capable.

70 centimeters (420-450 MHz): Secondary UHF band. Good for linking into repeaters. Many dual-band radios cover both 2m and 70cm.

National calling frequencies: Monitored by hams nationwide.

• 2m simplex: 146.520 MHz
• 70cm simplex: 446.000 MHz These are where you call to reach anyone listening locally without a repeater.

HF bands (General license required):

• 40 meters (7 MHz): Best for continental communication, especially evening and night. Primary emergency traffic band.
• 80 meters (3.5 MHz): Regional communication, excellent at night
• 20 meters (14 MHz): International communication when propagation allows

Programming Before an Emergency

A radio that isn't programmed with local repeaters before an emergency is nearly useless. Load the following:

1. Local repeaters (from repeaterbook.com — filter by your county and distance)
2. National calling frequencies (146.520 and 446.000 MHz simplex)
3. NOAA weather frequencies (162.400-162.550 MHz)
4. Local ARES/RACES net frequencies (ask your local amateur radio club)
5. Statewide emergency simplex frequencies (check your state's emergency plan — typically 155.340 MHz for interoperability)

See the CHIRP programming article for the full walkthrough.

The Next Step: Practice

Owning a ham radio and being prepared to use it in an emergency are different things. Join your local ARRL-affiliated radio club. Participate in weekly nets (on-air meetings). Take part in emergency communication drills.

ARRL's Emergency Communication training materials (EC-001 through EC-016) cover emergency communication procedures, net protocol, ICS integration, and more. Free online at arrl.org.

The operators who make a difference when disaster strikes didn't buy a radio, put it in a drawer, and pull it out when things went wrong. They practiced.
