Compared to a switching (switch mode) power supply, why may a linear power supply be preferred?

Switching power supplies (switch-mode power supplies) operate by rapidly turning current on and off at very high frequencies to regulate voltage. This high-frequency switching can generate significant radio frequency interference (RFI) or "hash" noise, which can easily be picked up by sensitive amateur radio receivers, raising the noise floor and masking weak signals. Linear power supplies, on the other hand, step down voltage using a large, heavy transformer and regulate it by dissipating excess voltage as heat. Because they do not use high-frequency switching circuits, they generate virtually no radio frequency noise. While linear power supplies are noticeably heavier, bulkier, and less electrically efficient than switching supplies, their completely quiet RF nature makes them highly desirable for amateur radio operators prioritizing a clean receiving environment.
