When doing VHF activations for Summits On The Air (SOTA), the radio range is dependent on the height of the summit and the surrounding terrain. The Radio Mobile website from Roger/VE2DBE is a great tool that can be used to estimate the radio range from a particular site. Repeater system owners often use tools like … Read more
Doing a simultaneous activation of a Summits On The Air (SOTA) summit and a Parks On The Air (POTA) park is becoming more common. There is a lot of crossover between the two programs. Here in Colorado, many of the SOTA peaks are in national forests or national parks, making them an ideal double activation. … Read more

I continue to learn about the file formats and various tricks for generating the logs. Some of this is not well-documented…at least I haven’t found it…so I am sharing what I’ve figured … Read more

This started before SOTA was even a thing, as I hiked in the Colorado mountains and made radio contacts just for fun. These days, we normally … Read more
Joyce/K0JJW and I have been doing combined Summits On The Air (SOTA) and Parks On The Air (POTA) activations. Most of the SOTA summits we activate are inside parks as defined by POTA. Our primary focus is using VHF/UHF from SOTA summits with POTA is being a nice addition. Although the two programs have a … Read more
