Artificial Radio Intelligence

In preparation for my upcoming article on “The Best Portable Shortwave Radios for 2025,” I asked Microsoft Copilot AI to consider a list of radios I’ve not personally used. It responded and in is confusion added a radio I didn’t ask about, the Tecsun PL-990.

Caution: sometimes Copilot is flat wrong (like saying the PL-990 has air band or that the C Crane Skywave SSB 2 has no antenna jack). Copilot found a number of mistakes when I asked it to fact check its own output. Below are its revised versions. Independent verification of the AI content is always prudent.
