Program these now. In a major earthquake, many repeaters lose power. This list is priority-ordered: start local with your county ARES repeater, step down to wide-coverage machines, then simplex. Listen before you transmit — don't add to congestion when a disaster strikes.

🌊 SoCal Earthquake Response — Step by Step
  • Listen first. After a quake, monitor your priority frequencies before transmitting. Avoid adding to congestion.
  • Start local → work outward. Try your county ARES/RACES repeater first. If active, check in with your call and location. If silent, try the next repeater down your list.
  • Repeaters down? Go simplex. Switch to 146.520 MHz. It's the universal meeting point when infrastructure fails.
  • APRS for "I'm OK" messages. 144.390 MHz. Even one position beacon tells the network you're safe without tying up a voice frequency.
  • HF is the ultimate fallback. If all local VHF/UHF infrastructure is gone, 3.992 LSB (night) or 7.192 LSB (day) reaches the entire state.
  • Solar-powered sites last longer. CARA (Catalina) repeaters run on solar and have the best chance of surviving extended grid outages. Prioritize them for longer-duration events.
  • Join ARES now — don't wait for a disaster. Your county ARES group will give you the exact current channel assignments and keep you in the loop. arrl.org/ares

Why simplex matters: In a major earthquake, repeaters can lose power or be damaged. Simplex frequencies work with any HT, require zero infrastructure, and are the universal fallback for every ham. Always program 146.520 first.

📻 Simplex Best Practices for SoCal Hams
  • Listen before transmitting. In the LA Basin especially, 146.520 can have ongoing QSOs you can only hear one side of due to terrain. Always listen for 10–15 seconds first.
  • Keep 146.520 for calling only. Make contact, then move to a working frequency like 146.550 or 146.535 for longer QSOs.
  • Program simplex AND repeaters. Alternate between simplex and your local repeater channels so you can quickly switch based on conditions.
  • Simplex range varies by terrain. In flat areas like the Coachella Valley or OC, HT-to-HT simplex can reach 10+ miles. In hilly LA, it might be 1–2 miles. A mobile antenna dramatically improves range.
  • SOTA & hiking. Use 146.580 (adventure frequency) for summit activations. Announce your freq on 146.520 first, then move.

🎙️ Net Etiquette — Quick Tips
  • Listen first. Before checking in, listen for 30 seconds to understand the format — directed or roundtable.
  • Full callsign clearly. Use phonetics if conditions are poor: "Kilo Echo 6 Mike Golf Bravo."
  • Keep check-ins brief. Most nets want: callsign, name, location. Save the long QSO for after the net.
  • Emergency traffic always goes first. Announce it immediately when NCS asks — it jumps to the head of the line.
  • ARES/RACES nets welcome listeners. Even if not enrolled, monitoring EmComm nets keeps you current on procedures.
🎉
Welcome to the hobby! Ham radio has been around over 100 years and Southern California has one of the most active ham communities anywhere. You picked a great time and place to get licensed.

You don't need to spend a lot to get started. Most new hams in SoCal start with a handheld transceiver (HT) that covers 2m and 70cm — the two most active bands locally.

RadioPrice RangeWhy It's Good for Beginners
Baofeng UV-5R / UV-82$25–$35Cheapest way to get on the air. Covers 2m and 70cm. Programming can be tricky — use CHIRP software (free). Popular, lots of online help available. Not the best audio quality but works fine for local nets and repeaters.
Yaesu FT-60R~$130Big step up in quality, durability, and audio. Easy to program manually. Very popular in SoCal EmComm — trusted by ARES/RACES operators. Great first "real" HT.
Yaesu FT-65R~$90Compact dual-band HT, waterproof, excellent audio. Great mid-range option if the FT-60R is out of budget.
Kenwood TH-D75A~$550Premium HT with built-in APRS, D-STAR, and a receiver covering almost everything. Not for most beginners — but worth knowing about when you're ready to upgrade.

The easiest way to program most HTs is with CHIRP — free open-source software that works on Windows, Mac, and Linux. Connect your radio via a programming cable and import channels directly.

📻 First 5 Channels to Program
  • 146.520 MHz simplex — National emergency calling. No PL tone. This is channel 1 in every SoCal ham's radio.
  • 146.385 + PL 146.2 — Keller Peak (KE6TZG) — The IE EmComm repeater. Wide coverage, very active, great for getting your first QSOs.
  • 446.000 MHz simplex — National 70cm emergency simplex. No PL tone.
  • 144.390 MHz — APRS — Set this as a receive-only channel so your radio can hear APRS traffic in your area.
  • Your county ARES/RACES repeater — Find yours in the Regions section of this site and add it to your radio now, before you ever need it.
🎙️ How to Check Into a Net (Your First QSO)
  • Tune to the frequency and listen for 30 seconds. Make sure it's not in use before transmitting anything.
  • When NCS asks for check-ins, press PTT and say just your callsign clearly: "Kilo Echo 6 Mike Golf Bravo"
  • NCS will acknowledge you and ask for your name and location: "My name is [your name], I'm in [your city], 73!"
  • That's it — you did it! Your first net check-in is the hardest part. It gets easier every time.
  • Best nets for beginners: Conejo Valley ARC Newbie Net (Sun 7PM, 147.885 −), CARA Net at Nine (daily 9AM, 147.090), and GOTA Hams Net (nightly 7:30PM, 449.160 −).

A local club is the fastest way to learn, meet other hams, and get access to club repeaters and equipment. Most clubs are free or very low cost to join. Find one near you:

Technician gets you on VHF/UHF. General class opens up HF (shortwave) — suddenly you can talk to hams across the US and worldwide. Most Technicians upgrade to General within a year. It's worth it!

🚨
ARES (Amateur Radio Emergency Service) is a volunteer organization of licensed hams who provide communications support during disasters and public events. In earthquake-prone SoCal, ARES operators are invaluable. You can join with any license class — Technician is perfectly fine to start. Contact your county Emergency Coordinator through arrl.org/ares.
⚠️
These are EmComm frequencies. Monitor before transmitting. During a disaster, listen first — check in only when you have something useful to report or when net control asks for check-ins.

📻
ARES
Amateur Radio Emergency Service

An ARRL program. Volunteer hams who provide emergency communications support for public agencies, hospitals, Red Cross, and other served agencies. Open to any licensed ham. Organized by county with an Emergency Coordinator (EC) in charge. No government affiliation — purely volunteer.

🏛️
RACES
Radio Amateur Civil Emergency Service

A government program administered by FEMA. Hams who are registered with their local government (city, county, or state) to provide communications during declared emergencies. Only activated during official declarations. In many SoCal counties, ARES and RACES members are the same people operating under different authorities depending on the situation.

🎙️ Getting Involved — Step by Step
  • Any license class can join ARES. Technician, General, and Extra are all welcome. You don't need HF privileges to be a valuable EmComm operator in your county.
  • Find your county EC. Use the ARRL's ARES section directory to find your county Emergency Coordinator. They're the point of contact for joining your local group.
  • Complete ICS training. Most SoCal ARES groups require ICS-100 and ICS-700 (free online through FEMA at training.fema.gov). Some also require ICS-200 and IS-800.
  • Check into the weekly ARES net. Each county has a weekly net — find yours in the Net Directory and start checking in. This is how you get to know the team.
  • Get RACES registered. Once you're active with ARES, your county EC can help you register with RACES through your county Office of Emergency Services.
  • Have your go-kit ready. A portable station with at least 12 hours of battery backup is the minimum. HT + spare battery, your ARES/RACES ID, and a copy of the county frequency plan.
