RFellow aims to provide practical RF engineering tools in a browser. Accessibility testing is ongoing, particularly for complex interactive charts.
Our engineering target is WCAG 2.2 Level AA. That is a goal, not a statement that RFellow currently conforms to the standard or has received accessibility certification. Applicable accessibility requirements depend on the service and jurisdiction. Independent keyboard, contrast, zoom and assistive-technology review is still required before public release.
Use Tab and Shift+Tab to navigate controls, Enter or Space to activate buttons, and browser zoom to enlarge content. RFellow offers light and dark themes and a display-size preference. Some graph interactions may also use the pointer, wheel or arrow keys. Support can vary between browsers and assistive technologies.
Cartesian and Smith charts convey information visually. Text markers and readings, selectable S-parameters and CSV export offer partial alternatives, but do not yet reproduce every interactive plot operation for screen-reader users. These limitations remain open review items.
Use Contact & Feedback to describe an inaccessible page, control or result. If helpful, mention your browser, device, assistive technology and the task you were trying to complete. Contact submissions are disabled in this development preview until secure delivery is configured. A working contact route or separately verified accessible alternative is required before publication.
RFellow is currently a web-based service without published visitor facilities. If additional physical services or support channels are introduced, their accessibility arrangements will be described here.
This draft was prepared on October 31, 2026. Before publishing, the site operator must review its accuracy, confirm the responsible contact details, record actual accessibility testing and update this statement when barriers are fixed.
