Aspiring radio amateurs in the United Kingdom preparing for their licensing examinations can utilize this resource, which offers mock exam questions covering the Foundation, Intermediate, and Advanced license levels. The site provides access to question pools, including associated images, designed for use with _Moodle_ learning management systems requiring PHP and MySQL. These question sets are available for non-commercial deployment by UK amateur radio clubs and organizations, facilitating local training initiatives. The original online mock test service ceased operations in August 2018 due to maintenance overhead. The current iteration serves as a repository, allowing other organizations to download the question databases. This approach enables broader access to the exam preparation material, supporting the UK amateur radio community in achieving licensing qualifications. The resource does not offer direct online testing but directs users to other sites, such as _Radio Tutor_, that implement these question banks.

One hundred and fifty words per minute (WPM) is a configurable speed setting in this online Morse code translator, which facilitates bidirectional conversion between plain text and **Continuous Wave (CW)**. Users can input text to generate corresponding Morse code, or enter Morse code using dots and dashes to receive a text translation. The tool supports various alphabets, including Latin, Cyrillic, Ukrainian, Hebrew, and Arabic, broadening its utility for international communication. The platform offers multiple output methods for the generated Morse code, including audible playback, visual flashing, and device vibration. Advanced configuration options allow for precise control over the sound's pitch (frequency), volume, and overall speed, including a **Farnsworth speed** setting. This flexibility enables users to customize the learning or communication experience to their specific needs. Additional features include the ability to save the generated Morse code audio as a WAV file and to create shareable links for messages, which can be sent with or without the accompanying text. The interface is entirely web-based, built with HTML5 and JavaScript, ensuring broad compatibility across modern browsers.
