Is the WeatherStar I still being used?
I hope not! Actually, the WeatherStar I caused so much RF interference that it was quickly changed to the WeatherStar II, which itself didn't last long before the more advanced WeatherStar III was developed. Since the WeatherStar III was given the kibosh by the FCC for not being able to sound a warning tone at the beginning of every repeat of a weather warning, I think it's extraordinarily unlikely that there's a functioning WeatherStar I anywhere. In fact, I doubt there was a functioning WeatherStar I in use anywhere by the time the 1980s ended, if even that late.
