Colorado 14er Event – Now With SOTA!

Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. The prime operating hours on August 5th are from approximately 9 AM to noon local time (1500 to 1800 UTC), but activity may occur at other times during the day.

New this year: Summits On the Air (SOTA)  activity, which adds 1700 additional potential 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 W0 SOTA web page for details.

Radio operators that plan to activate a summit should register their name and intended peak at the ham14er Yahoo! group.  To subscribe to the event mailing list, visit the yahoo groups site at . Also, be sure to check out the event information at

Frequencies used during the event
Activity can occur on any amateur band including HF and VHF. The 2M FM band plan uses a “calling frequency and move up” approach. The 2M FM calling 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, operators should move up the frequency using the standard channel spacing used in Colorado (15 kHz). Don’t just hang out on 147.42 MHz…move up! The next standard simplex frequency up from 147.42 MHz is 147.435 MHz, followed by 147.45, 147.465, 147.480, 147.495, 147.51, 147.525, 147.54, 147.555, 147.57 MHz.

Don’t just hang out on 147.42 MHz…move up and share the band.
