The order would implement a 2.8 kilohertz bandwidth limitation in place of the baud rate in amateur radio bands. The 2.8 kHz limitation is consistent with the commission’s treatment of other wireless radio services, the FCC says. The current rules limit the baud rate for high-frequency amateur...
The FCC's action follows their 2023 decision to remove the baud rate limits on the 160- to 10-meter amateur bands. Those limits were replaced with a 2.8 kHz bandwidth limit - a move ARRL had long advocated for.QST: Devoted entirely to amateur radio...

Thank you for mentioning "spectrum" and better clarification regarding bands. I frequently make the mistake of lumping amateur radio all-in within the 2m/70cm while there is a whole lot more out there and some parts of the band can not have a repeater on them. (Nor would they work that...

Part 15 governs a broad range of the radio spectrum ranging from below 1 MHz to in excess of 32 GHz. It is broken into individual sections that govern the use of specific frequencies and bands. For example, section 15.249 covers the 902-928 MHz band. In this frequency range a user is ...
