Quote: "In theory, digital tuners should not go out of alignment, although I owned one in the early 1980s that did malfunction."

i used to have a very good tuner: Technics ST-G7, and it happened one time i phoned the CBC to tell them their FM transmitter was slowly slipping off frequency.
they asked "how do you know that?"
i said: my tuner is a Technics STG7.
they said: ah, ok.
