Do radio receivers wear out?

Eventually, they do. There are no physical wear-out mechanisms except for moving parts in controls or switches, but a process called "component ageing" will ultimately make the receiver stop working. read more

The circuitry in a radio receiver doesn't physically wear out, no. Repeated powering-on and powering-off of any device does gently heat electronics up and cool them down, and this can, eventually, cause physical breaks in the technology - particularly in mains power supplies. read more

In consumer electronics, the terms radio and radio receiver are often used specifically for receivers designed to reproduce sound transmitted by radio broadcasting stations, historically the first mass-market commercial radio application. read more

Should you lose the digital signal for some reason (obstructing terrain, nearing the edge of the broadcast area, etc.), HD Radio technology defaults back to analog mode, similar to the way non HD Radio receivers switch from stereo to mono mode when receiving a weak signal. read more
