SOTA: Summits on the Air and Amateur Radio Licensing

Summits on the Air (SOTA) is an international amateur radio program that encourages operators to carry radio equipment to designated mountain summits and make contacts from the summit. SOTA combines the physical challenge of mountaineering with the technical challenge of operating a radio station in a remote, exposed environment. The program has attracted a passionate global following since its establishment in 2002.

How SOTA Works

SOTA designates specific mountain summits in each country based on prominence and point value. Higher, more prominent summits earn more points. To score a valid activation, the operator must:

• Be physically on the summit (within a defined "activation zone" near the top)
• Make at least four contacts with other stations
• Not use a vehicle-mounted power source at the summit
• Log and submit the activation to the SOTA database

Equipment Challenges

SOTA operations require portable, lightweight equipment that can be carried in a hiking pack to the summit. Popular SOTA setups include:

• QRP (low-power) transceivers like the Elecraft KX2, Xiegu X6100, or Mountain Topper
• Lightweight wire antennas (EFHW — End Fed Half Wave — is very popular for SOTA)
• Small lithium batteries to minimize weight

License Requirements

SOTA uses HF bands extensively — 40 and 20 meters are the most popular for reaching chasers nationwide. This requires a General class license or higher. Some operators do VHF/UHF SOTA, which requires only Technician class, but the contact count and range are more limited without HF access.

SOTA Awards

SOTA tracks points for both activators (who go to summits) and chasers (who contact them from home). Points accumulate, and awards are given at milestone levels — Mountain Goat for activators who accumulate 1,000 points, Shack Sloth for chasers who accumulate 1,000 points. The dual structure of activating and chasing makes SOTA engaging year-round regardless of whether you are physically able to hike.
