For SOTA (Summits on the Air): Ultra-lightweight gear is essential. Consider the Elecraft KX2 or Mountain Topper for minimal weight. I'm torn between these two for upcoming activations. The IC-705 has all-mode capability and built-in battery, but the KX2 is lighter and has that legendary Elecraft receiver.

Has anyone done back-to-back comparisons on actual summits? For some remote summits, it can be a challenge to get enough radio contacts (4) to qualify for the SOTA points. Using HF can be a big help in generating contacts. Which radio gives you better odds of making those crucial 4 contacts?

I've used both extensively. The LiFePO₄ battery performance under load has been excellent running multiple radios, including high-powered HF rigs. The KX2's receiver is noticeably better in crowded band conditions, but the IC-705's VHF/UHF capability gives you more options on difficult summits.

Weight is everything on long hikes to summits. I switched from IC-705 to KX2 last year and saved about 8 ounces in my pack. VHF/UHF is a good match for SOTA (Height Above Average Terrain). However, for some remote summits, it can be a challenge to get enough radio contacts (4) to qualify. The KX2's CW capability really shines for weak signal work.

As someone new to SOTA, I appreciate this discussion! Still learning about the point values based on elevation and scoring systems for both activators and chasers. Are there any other ultra-lightweight options worth considering for us QRP folks?
