A Tale of Two Radios: CommRadio CTX-10 vs. Elecraft KX2
By Thomas Witherspoon K4SWL

A longtime ham and shortwave listener who enjoys taking his hobby into the field, Thomas was intrigued by two seemingly different transceivers that also appeared to have a lot in common. Which would be better for his purposes and why? Both offer low-power and battery-operated portability, but with a totally different design approach. Thomas examines the pros and cons of the CommRadio CTX-10 and the Elecraft KX2, not the least of which in the monetary component.

The Trailblazers of Commercial Radio Manufacturing in the 1920s

  • Karl WA8NVW:

    MATT –
    Time to adjust your glasses or motivate the Amateur Radio.com proofreader?? The teaser line for this e-issue reads “Stories you’ll find in our May, 2018 issue: ” which seems to be about 21 months behind the calendar.
    Seriously though, the mag cover photo correctly shows February, 2020 issue, and your article index is intriguing.

  • Thank you, Karl! Fixed!
