Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peaks in an effort to communicate with other radio amateurs across the state and around world. Join in on the fun on the first full weekend in August and see how many of the mountaintop stations you can contact. The prime operating hours are on Sunday August 2nd from 9 AM to noon local time (1500 to 1800 UTC), but activity can occur throughout the weekend.
Now including Summits On the Air (SOTA), which adds over 1700 potential summits! If you aren’t up to climbing a 14er, there are many other summits to choose from (with a wide variety of difficulty). See the W0C SOTA web page at w0c-sota.org
Radio operators who plan to activate a summit should set an “Alert” on the SOTAwatch.org web site.

Frequencies used during the event
Activity can occur on any amateur band including HF and VHF. The 2m fm band plan uses a “primary frequency and move up” approach. The 2m fm primary frequency is 147.42 MHz. At the beginning of the event, operators should try calling on 147.42 MHz. As activity increases on that frequency, move on up the band using the 30 kHz steps. Don’t just hang out on 147.42 MHz…move up! The next standard simplex frequency up from 147.42 MHz is 147.45 MHz, followed by 147.48, 147.51, 147.54 MHz.
