Amateur Radio Fun in the Colorado Mountains
August 7 & 8, 2021

Amateur Radio operators from around Colorado will be climbing many of Colorado's 14,000-foot mountains and Summits On The Air (SOTA) peaks to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Join in on the fun during the annual event and see how many of the mountaintop stations you can contact. This year the event is expanded to include the entire weekend. However, many mountaintop activators will hit the trail early with the goal of being off the summits by noon due to lightning safety concerns.

The 14er event includes Summits On the Air (SOTA) peaks, which adds over 1700 summits! If you aren’t up to climbing a 14er, there are many other summits to choose from (with a wide range of difficulty). See the W0C SOTA web page at This year, we are celebrating the 10th Anniversary of SOTA in Colorado, so the 14er event is the kickoff of ten days of SOTA activations! See

Important: The recommended 2m FM frequencies have been changed to 146.58, 146.55, and 146.49 MHz, to align with the use of the North America Adventure Frequency for SOTA (146.58). The National Simplex Calling Frequency (146.52) may be used as appropriate. See the operating frequencies page.

Radio operators who plan to activate a summit should post their intent to this ham14er group by adding it to the database. It is also a great idea to post an ALERT on the SOTAwatch website.
