Today, January 13, 2026, marks Public Radio Broadcasting Day. While digital media evolves, radio remains a uniquely reliable lifeline, reaching listeners where the internet cannot. To celebrate, we are highlighting a favorite for enthusiasts and professionals alike: the NEW 2025 United States Frequency Allocations: The Radio Spectrum Poster.
Available through the Government Publishing Office U.S. Government Bookstore, this best-selling poster is the definitive visual guide to our nation’s airwaves. It transforms the invisible infrastructure of communication into a clear, color-coded map.
The poster utilizes color codes to illustrate the parts of the radio spectrum allocated to various types of radio services, including amateur (ham) radio, commercial radio, television broadcasting, radio navigation, mobile, satellite, and others. Essential facts about the poster include the following:
- The definitive and most current official copy of the 2025 US Radio Spectrum Frequency Allocations, crucial for regulatory adherence and operational planning.
- Substantial size for optimal readability: 39″ x 27″ (inches).
- Expertly printed using fade-resistant, premium archival inks on high-grade 100 lb. premium matte paper. This ensures vibrant colors, crisp detail, and long-term durability.
- Proudly Made in the USA.
- Unframed, offering flexibility for the buyer to customize their display.
For those who want to dive deeper into the rules of the road, the Manual of Regulations and Procedures for Federal Radio Frequency Management is also available to explain the “how” behind the map.

As a strong fan of radio and having written about radio history, I question your statement “The first commercial radio station was KDKA in Pittsburgh, Pennsylvania, which began broadcasting in 1920.” It was the first LICENSED station on the air regularly. WWJ in Detroit was the first station to go on the air and broadcast regularly, but didn’t have the license at first. See my blog posting: https://kensintrospect.wordpress.com/2020/08/19/happy-birthday-radio-100-years-of-broadcasting-history. Thanks for your site, I enjoy it.
