Voice of America (VOA): A Brief Overview and Historical Context

Voice of America (VOA) 1st Day Cover - RF CafeVoice of America (VOA) is a U.S. government-funded international multimedia agency that provides news, information, and cultural programming to audiences outside the United States. It is part of the U.S. Agency for Global Media (USAGM), an independent agency of the U.S. government. VOA was established in 1942 during World War II with the aim of countering Nazi propaganda and promoting American values and policies abroad. It initially broadcast in German, and later expanded to other languages. Today, VOA broadcasts in more than 40 languages, including English, targeting a global audience. VOA operates through radio, television, and digital platforms, reaching millions of people worldwide. Its programming covers a wide range of topics, including news, current affairs, culture, education, and entertainment. VOA strives to provide accurate and objective reporting, offering diverse perspectives on global events and issues. As a U.S. government-funded entity, VOA is subject to the principles of the VOA Charter, which mandates that it provide accurate, objective, and comprehensive news and information. The agency aims to promote democracy, freedom of expression, and the values of a free press. It's worth noting that while VOA is funded by the U.S. government, it operates independently and maintains editorial independence. Its journalists and broadcasters are expected to adhere to professional journalistic standards and avoid promoting any particular political agenda. Overall, VOA plays a significant role in international broadcasting, providing news and information to audiences worldwide and serving as a platform for dialogue and understanding between different cultures and nations.

AI Technical Trustability Update

While working on an update to my RF Cafe Espresso Engineering Workbook project to add a couple calculators about FM sidebands (available soon). The good news is that AI provided excellent VBA code to generate a set of Bessel function plots. The bad news is when I asked for a table showing at which modulation indices sidebands 0 (carrier) through 5 vanish, none of the agents got it right. Some were really bad. The AI agents typically explain their reason and method correctly, then go on to produces bad results. Even after pointing out errors, subsequent results are still wrong. I do a lot of AI work and see this often, even with subscribing to professional versions. I ultimately generated the table myself. There is going to be a lot of inaccurate information out there based on unverified AI queries, so beware.
