The AM/MW band will be abandoned in next 20 years due extensive use of inverters in cars and buildings.

Vote: No

Abandoned in the next 20 years is too strong. AM/MW use will likely keep shrinking, but full abandonment is unlikely. Interference from inverters, EVs, solar systems, LED drivers, and switching power supplies is a real problem. It raises the noise floor and hurts reception, especially in dense urban areas. But spectrum does not disappear just because listening becomes harder. AM/MW still has unique strengths: very large coverage area, low receiver cost, and usefulness in emergencies when cellular or internet access is degraded. Governments, regulators, public broadcasters, and niche operators often keep legacy bands alive for resilience reasons. Also, abandonment would require coordinated action by many countries, broadcasters, receiver makers, and regulators. That kind of global shutdown is slow and uneven. More likely is a continued decline, reduced commercial importance, and survival in selective regions and use cases rather than total abandonment.

While electromagnetic interference (EMI) from inverters in electric vehicles and modern buildings poses a significant challenge to AM/MW radio reception, the band will not be abandoned in the next 20 years for several compelling reasons. First, AM radio remains a critical backbone of emergency alert systems (EAS). Government agencies, such as FEMA in the United States, rely heavily on the AM band's unique long-range signal propagation to broadcast life-saving information during major disasters when cellular and internet networks fail. Second, significant political and regulatory pushback has already materialized to protect the band. For example, bipartisan legislation like the 'AM Radio for Every Vehicle Act' demonstrates a strong governmental will to mandate AM receivers in new cars. Instead of abandoning the band, manufacturers are being pressured to implement better EMI shielding and noise-filtering technologies. Finally, AM radio still serves millions of listeners globally, particularly in rural and remote communities where FM and cellular signals simply cannot reach. Because of its irreplaceable role in public safety and rural connectivity, the AM/MW band will be preserved rather than abandoned.

AM/MW radio has persisted for over a century despite waves of electronic interference from TVs, computers, and cell phones. Inverters in EVs and solar systems do generate EMI in the AM band, but this is not new or insurmountable. Strict regulations like FCC Part 15 and CISPR 25 mandate EMI limits for inverters and vehicles, with manufacturers required to use shielding, filters, and ferrite cores to suppress noise. Modern inverters are far better than early models. AM remains vital for emergency alerts (e.g., US EAS), long-range propagation, and niche audiences like sports/talk radio. Recent NHTSA rules forced automakers to retain AM tuners despite EV interference complaints. No credible forecasts predict abandonment; instead, innovations like noise-cancellation receivers and digital overlays (HD Radio) address issues. Full abandonment in 20 years is speculative hype, ignoring regulatory and practical resilience.

The premise that AM/MW will be abandoned specifically due to inverter noise is overly simplistic, and the conclusion that it will happen within 20 years is unlikely for several reasons. First, while inverter noise is a real problem for AM reception (particularly in EVs and near solar installations), the radio industry and automotive manufacturers are actively developing noise mitigation techniques, including better shielding, filtering, and digital signal processing. BMW famously dropped AM from EVs but later reversed course under regulatory pressure. Second, multiple countries have actually enshrined AM radio protection into law. The US passed the AM Radio for Every Vehicle Act with strong bipartisan support, mandating AM radio in new cars. This shows strong political will to preserve the band. Third, AM/MW serves a critical role in emergency broadcasting. It has unique propagation characteristics—covering vast areas with a single transmitter and penetrating buildings—that make it irreplaceable for disaster communications. Governments worldwide recognize this strategic value. Fourth, while some countries are transitioning to DAB or DAB+, this is happening alongside AM, not because of inverter interference, but due to bandwidth and audio quality considerations. Even so, complete AM abandonment within 20 years would require a globally coordinated spectrum reallocation, which is extremely unlikely given the diverse needs of different nations. Finally, the installed base of AM receivers worldwide is enormous, particularly in developing countries where AM remains a primary information source. The infrastructure and regulatory inertia alone make a 20-year abandonment timeline implausible.

Final Summary

The AI Roundtable reached a swift and unanimous consensus, firmly rejecting the idea that AM radio's death is imminent due to inverter noise. While GPT-5.4 and Grok 4.1 Fast focused on technical mitigation and regulatory inertia, Gemini 3.1 Pro and Claude Opus 4.6 highlighted the band's existential importance to national security and emergency communications.
