The first summit I activated was a 2,400-foot hill in Virginia. 45-minute hike, 5W radio, a wire thrown over a dead branch. Made 12 contacts in 25 minutes — including two European stations who were specifically looking for me.

Walking back down with a successful activation logged, I understood why SOTA people seem borderline obsessed. It combines everything good about ham radio (challenge, achievement, propagation magic) with everything good about hiking (nature, exercise, solitude, views).

What SOTA Is

Summits on the Air — an award scheme where you earn points by making radio contacts from designated mountain summits. Each summit has a reference number and a point value based on height.

Key facts:

  • Minimum 4 contacts from the summit activation zone to count
  • Only human-powered access counts (no driving to the top)
  • Activation zone: within 25 vertical meters of the summit
  • Points range from 1 (small hills) to 10 (major peaks)
  • No repeater contacts — must be simplex or direct

How It Differs from POTA

POTA SOTA Location Parks (drive up) Summits (hike up) Minimum contacts 10 4 Access Vehicle OK Human-powered only Point system Per park Height-based per summit Physical difficulty Easy Varies (walk to mountaineering) Weight sensitivity Low Critical

POTA rewards operating time and contacts. SOTA rewards physical effort and altitude. Many hams do both.

Equipment: Weight Is Everything

Every ounce matters when you're carrying it uphill for 2 hours. My SOTA kit:

Radio: Elecraft KX2 (0.9 lbs) or IC-705 (2.2 lbs). The KX2 on peaks with serious hikes. The IC-705 when I want VHF/UHF satellite opportunities at the summit.

Antenna: End-fed half-wave wire (40m, ~53 feet). Total weight including unun and wire: 4 oz. Throw line gets it over a tree branch or I support it with a collapsible fishing pole.

Mast (when no trees): SOTABeams 6m carbon fiber pole — 10 oz. Supports a wire inverted-V above treeline where there's nothing to hang from.

Battery: KX2 internal (8 hours). Or Bioenno 3Ah (0.7 lbs) for the IC-705.

Logging: Phone + HAMRS app or pencil + paper (batteries die in cold).

Support: Throw line, coax jumper, earbuds, pen, activation log sheet.

Total radio kit weight: 2-4 lbs depending on configuration. That's on top of normal hiking gear (water, food, first aid, layers, navigation).

Planning an Activation

1. Find Your Summit

sotadata.org.uk → Summit Database → search by location. Or use SOTAMaps for a visual map.

Filter by:

  • Drive time: How far is the trailhead?
  • Hike difficulty: Elevation gain, trail length, terrain
  • Point value: Higher summits = more points (but harder hikes)
  • Previous activations: Has it been activated before? (First activations get bonus points)

Start with 1-2 point summits (low hills). My first was a well-maintained trail, 1.5 miles, 700 feet gain. Easy. Build confidence before attempting anything serious.

2. Check the Rules

  • Must operate within 25 vertical meters of the summit point
  • Must ascend under own power from the last motorized transport point
  • Final approach cannot use any motorized vehicle/lift
  • No minimum time at the summit
  • Self-spot is fine (use SOTA spotter or SMS)

3. Choose Bands and Modes

CW on 20m — highest success rate for fast activations. CW chasers monitor 14.062 MHz area constantly. SOTAwatch spots trigger instant pileups.

SSB on 20m — works well, especially weekends. More chasers available. Slightly slower rate than CW.

FT8 — works but requires a laptop (weight penalty). Save for tough propagation days.

2m FM — if your summit has line-of-sight to populated areas. Simple, fast contacts. Good for padding your contact count to 4.

4. Alert and Spot

Alert: Post on SOTAwatch (sotawatch3.sota.org.uk) 24 hours before. Chasers check alerts and plan to be on-frequency.

Spot: When you're at the summit and on the air, self-spot via:

  • SOTA Spotter app (cell service required)
  • APRS (if you have a VHF radio)
  • SMS to a friend who spots for you

Spotting is essential. Without a spot, you might call CQ for 15 minutes. With a spot, you'll have 5+ chasers within 2 minutes.

Operating from the Summit

The ideal activation flow:

  1. Arrive at summit. Set up antenna (5-10 min).
  2. Self-spot on SOTAwatch.
  3. Call: "CQ SOTA CQ SOTA [callsign] on [summit reference]"
  4. Work chasers. Exchange: signal report + summit reference.
  5. Log contacts. Minimum 4 to count.
  6. Optional: move to another band/mode for more points.
  7. Pack up. Hike down.

Most activations take 20-45 minutes of operating time. Total summit time including setup: 30-60 minutes.

Chasing (From Home)

Don't want to hike? Chase activators from your home station:

  1. Watch SOTAwatch spots page
  2. Tune to spotted activator's frequency
  3. Call them — be brief (they're cold, windblown, and have a queue)
  4. Log the contact for chaser points

Chasers earn points too. Different awards for total summits chased, unique summits, etc.

Scoring and Awards

Activator points: Based on summit height. 1-10 points per summit. Season bonus: winter activations (Dec-Mar in northern hemisphere) earn 3 extra points.

Awards:

  • Mountain Goat: 1000 activator points (the prestigious one)
  • Shack Sloth: 1000 chaser points
  • Various summit-count milestones

Mountain Goat takes years of regular activations for most people. The journey is the point.

Safety

SOTA takes you into the backcountry. This isn't a park picnic table.

  • Tell someone your plan. Summit name, expected return time.
  • Check weather. Summits create their own weather. Lightning kills people on exposed peaks.
  • Know your fitness level. Don't attempt a 4,000-foot gain hike because the summit is worth 8 points if you've never hiked more than 2 miles.
  • Carry the ten essentials. Navigation, sun protection, insulation, illumination, first aid, fire, repair, nutrition, hydration, shelter.
  • Turn back if conditions deteriorate. The summit will be there next week.

I've turned back from three planned activations due to weather. Zero regret. The radio will work fine from home.

Why SOTA Hooks People

There's a specificity to it. Not just "I operated portable" but "I carried my radio to this exact summit, set up an antenna in the wind, and made contacts that only existed because I was on that peak at that time."

Every activation is a memory tied to a place. The summit where I worked 30 stations in 20 minutes. The one where I barely got 4 contacts before a storm rolled in. The winter activation where my fingers were too cold to send CW faster than 10 WPM.

That combination of physical challenge and radio achievement is unique in the hobby.
