The New Ham Radio License Rules 2024

The New Ham Radio License Rules 2024


In the world of amateur radio, changes to licensing can stir up a mix of excitement and confusion. On the 21st of February 2024, the UK licensing authority made significant updates to the radio amateur license conditions. While some operators are pleased with the changes, others are finding themselves navigating through new territory.

Prefix Confusion

In the UK, call signs are structured with prefixes that indicate the location within the United Kingdom. For example, GM for Scotland, GI for Northern Ireland, GW for Wales, and G for England. Under the new licensing conditions, operators are no longer required to use their prefixes. This means that an operator based in Scotland with a call sign of GM3ZZZ could now simply sign themselves as G3ZZZ, eliminating one character from their call sign.

While this change may seem advantageous for English operators who have shorter call signs, it can lead to confusion, especially during contests or when looking up call signs in databases. Missing prefixes could potentially label operators as pirates or cause discrepancies in call books and online databases.

Suffix Innovations

Additionally, the new license conditions allow for more flexibility in suffixes. While traditional suffixes like /A for alternative address, /P for portable, /M for mobile, /MM for Maritime Mobile, and /AM for aeronautical mobile were common, operators can now use a wider range of suffixes of their choice.

While some operators may opt for creative suffixes like /DG for down the garden or /IP for in the park, the possibilities for inventing unique call signs are endless. However, this freedom in suffix selection could potentially lead to confusion and misunderstandings on the airwaves.

Power Limitations

One of the notable changes in the new licensing conditions is the increase in power limitations. Foundation license holders saw an increase from 10 watts to 25 watts, intermediate license holders from 50 watts to 100 watts, and full license holders from 400 watts to 1,000 watts.

Interestingly, the power delivered to the antenna is what determines compliance with the power limitations. This means that factors like antenna efficiency and feedline losses can impact the effective power output. Operators may find themselves able to legally run higher power levels based on the losses in their setup.


As amateur radio operators adapt to the new license conditions, there are bound to be discussions, ponderings, and perhaps a few challenges along the way. Whether it's navigating through prefix changes, exploring innovative suffix options, or optimizing power delivery to antennas, the evolving landscape of ham radio licensing offers both opportunities and complexities.

While the changes may bring about some initial confusion, they also present an opportunity for operators to explore new aspects of the hobby and enhance their radio experiences. As operators embrace these changes, they contribute to the dynamic and diverse community of amateur radio enthusiasts.
