Interesting Wikipedia article, Michael. Thank you. I fully agree with the authors of the article, who claim that cable radio stations were justified only in mountainous areas with extremely poor conditions for radio signal transmission. I have one very interesting 1936 Albis V 5TRV Swiss cable radio in my collection. It can receive up to 5 radio stations while waiting for a call from a telephone exchange and provide high-quality sounding of a telephone conversation with a subscriber. But I can't demonstrate it like the necessary equipment from a telephone exchange. It is interesting that all signals were transmitted at a low frequency and in fact it is not a radio receiver but a low frequency amplifier with a telephone switch at the input.
