Electronics enthusiasts are discussing how buck converters switch a MOSFET at high frequency, generating RF noise whose harmonics can fall directly inside amateur radio bands. The conversation covers searching for switching regulators whose frequencies avoid these bands, noting that low-frequency alternatives require larger and more expensive components.
