The Popular Science article with a picture of your clock radio is from 1971. And I'd love to have one of those Scott tuners with the Nixie frequency readout! |
Heathkit came out with an FM tuner featuring a Nixie-tube readout in the late 1960s-early seventies. It could be "tuned" with a ten-key (0-9) keypad on the front panel or by means of preprogrammed cards for each of the 300 FM radio channels (channel 201 was 88.1 MHz, going to channel 300, 107.9 MHz). The station's callsign could be written on the card corresponding to its frequency.
I don't know whether or not Heathkit got the idea from HH Scott; in fact, until I read this post, I did not realize the latter had a programmable FM tuner with a digital readout. My best guess, however, is the Heathkit tuner was modeled after the HH Scott design.
