Your First SOTA Activation: Complete Guide

Summits on the Air (SOTA) is an international amateur radio award program where operators hike to designated summits and make at least four contacts from the Activation Zone — typically within 25 vertical meters of the true summit. It's one of the fastest-growing activities in the hobby, combining real outdoor adventure with portable HF operating. This guide walks you through your first activation from planning to log submission.

Step 1: Choose Your Summit

Every qualifying SOTA summit is listed in its Association's Reference Manual (ARM) — the database of summits with point values (1–10 points based on prominence and height). Find summits in your area using SOTAmaps.org or the SOTA Goat app (iOS/Android). Each summit has a reference number like W7W/LC-001 — the format is Association/Region-Number.

For your first activation, choose a summit you can reach comfortably with a pack. A 2-mile round-trip hike with 600 feet of gain is much more enjoyable than a 10-mile epic when you're also hauling radio gear. Higher point values (8–10) require real effort — save those for after you've got the process down.

Step 2: Build Your Activation Kit

Weight is the enemy. Here's what experienced SOTA activators carry and why:

Step 3: Post an Alert (The Night Before)

Log in to SOTAwatch3 and post an Alert for your planned activation. Include your summit reference, planned start time (UTC), and operating frequencies/modes. Chasers around the world subscribe to alerts and will be waiting for you. Even a rough time estimate dramatically increases your contact rate — without an alert, you're cold-starting from zero.

Step 4: On the Summit — Operating

Set up your antenna first. An EFHW strung between two trees or supported on a mast at 15–20 feet works well. Connect your radio, check SWR (aim for under 2:1), and self-spot via the app with your exact frequency.

Calling CQ SOTA

Standard CQ call on SSB: "CQ SOTA, CQ SOTA, this is [callsign], [callsign], [callsign], calling CQ Summits on the Air and standing by." On CW: CQ SOTA DE [CALL] K. Once spotted, you'll often have a pileup within 60 seconds — especially on 20m where European chasers are frequent.

The Exchange

SOTA exchanges are brief: callsign, signal report, summit reference. Example: "W7XYZ, you're 59, summit reference Whiskey Seven Whiskey stroke Lima Charlie Zero Zero One." Log it and move on. During a busy pileup, keep exchanges under 30 seconds. Chasers are experienced — they know the drill.

If You Can't Get 4 Contacts

Try a different band. 2m FM simplex often works near populated areas — call CQ on 146.520 MHz (national simplex calling frequency). Many activators carry a lightweight dual-band HT as a backup for exactly this situation. A single 2m FM contact counts the same as a 20m SSB contact.

Step 5: Submit Your Log

After the hike, log in to SOTAdata.org.uk and submit your activation log. You'll need: summit reference, date, UTC times, callsign of each chased station, band, mode, and signal reports. The SOTA Goat app can submit directly. Points credit to your account, and cross-matched contacts credit the chaser's account simultaneously.

Key SOTA Resources

• SOTA.org.uk — Program home, Association Reference Manuals, rules
• SOTAwatch3 — Alerts, spots, real-time activator tracking
• SOTAmaps.org — Interactive summit finder with trail overlays
• SOTAdata — Log submission and score tracking
• HAMRS App — Mobile logging app with SOTA template

Choosing Your Operating Mode: SSB, CW, or FT8 from a Summit

SSB remains the fastest way to pile up four contacts quickly. Call CQ on 14.285 MHz (20m phone) or 7.285 MHz (40m phone), post your spot on SOTAwatch, and chasers who follow alerts will answer within seconds. A typical SSB activation with a good spot nets 10–20 contacts in under 30 minutes.

CW (Morse code) activations appeal to experienced operators because the CW sub-bands are less congested, CW signals propagate further at the same power level, and many chasers specifically prefer CW contacts for their logs. If you're comfortable above 15 WPM, try 14.060 MHz (20m CW) or 7.030 MHz (40m CW). CW activations often produce more contacts with DX stations, particularly European chasers.

FT8 from a summit requires a laptop or tablet with WSJT-X and a time source (GPS dongle or cell signal for clock sync), but it's increasingly popular for remote activations where voice contacts are difficult due to antenna limitations. The Elecraft KX2 and KX3 both support digital mode operation via their USB ports with minimal additional hardware.

Understanding Summit Point Values

SOTA summits earn activators points based on height and topographic prominence. The scale runs 1 to 10 points:

• 1 point: Summits between 150m and 249m of topographic prominence (or above 150m ASL in flat regions). Easy hikes, good for first activations.
• 2 points: 250–499m prominence. Still accessible but a real hike.
• 4 points: 500–749m. Serious terrain, typically requiring trail experience.
• 6 points: 750–999m. Full-day hikes or multi-pitch scrambles in many regions.
• 8 points: 1,000–1,249m. Technical terrain possible depending on region.
• 10 points: 1,250m+ of prominence. Winter operation earns 3 bonus points on all summits above 1,000m ASL.

Working Summit-to-Summit (S2S)

A Summit-to-Summit contact — where both the activating station and the chaser are also on a SOTA summit simultaneously — earns the activator an additional S2S point separate from the summit activation points. S2S contacts are logged separately and award both operators bonus points. Monitor SOTAwatch alerts to see who else is active on summits the same day. On a busy SOTA weekend, calling CQ on simplex VHF (147.540 MHz or your regional SOTA simplex calling frequency) can connect you with other summit operators you'd never find on HF.

Winter Activations: Bonus Points and Extra Preparation

Any summit above 1,000m ASL that you activate between December 1 and March 31 (in the Northern Hemisphere) earns 3 bonus points on top of the standard point value. A 10-point winter summit earns 13 points — significant for operators chasing Shack Sloth or Mountain Goat award levels. However, winter activations require serious preparation beyond what a summer hike demands. Cold kills batteries faster — LiFePO4 chemistry handles cold better than lithium polymer but still loses significant capacity below 0°C. Protect batteries by keeping them inside your jacket until you operate. Bring chemical hand warmers for the battery and your hands. Wet weather gear, microspikes, and trekking poles are essential depending on the summit.

Logging Tools and App Recommendations

The SOTA Goat app (iOS, ~$5) is the most popular logging and spotting tool for iOS users. It handles logging, self-spotting to SOTAwatch, and direct log submission to SOTAdata, all from one interface. For Android, HAMRS is free, works offline, and has a dedicated SOTA logging template that captures all required fields. Paper logging remains the most reliable backup — waterproof notebook and a pencil (not pen — ink freezes) are standard kit for serious activators.

Log the following for each contact: UTC time, callsign, band (e.g., 20m), mode (SSB, CW, FM), and signal report given and received. Summit reference and date are logged once per activation, not per contact. Upload to SOTAdata within 24 hours while the contacts are fresh and your memory is reliable.
