• Antifeding — An orthographic variant or secondary graphic fluctuation in Romanian for the technical term 'antifading'; a property or circuit capable of compensating for radio signal intensity fluctuations. Although modern standards recommend 'antifading', the form with 'e' survives in older engineering papers.
• Autodynes — The plural form of the noun autodină; a collection of electronic circuits or historical radio receivers based on using a single active element as both detector and local oscillator.
