Historical radios

In the rooms of the Schatzalp you will find ‘historical radios, and there is a story behind them as well!

Biennophone Minitel 43 NB

 

The hotel Schatzalp wanted to enable its guests to receive radio broadcasts in the rooms more than 50 years ago. At that time, however, the operation of a radio was not easy, and the radio reception of stations in mountainous areas was a matter of luck. In 1931, however, the telephone claim was introduced in Switzerland. This allowed the radio reception of six transmitters of acceptable quality over the telephone line.

The suitable for telephone radio devices were quite simple and easy to use:

  • On / Off button
  • Volume control
  • 6 buttons for 6 radio station

At the Schatzalp 3 ‘generations’ of these devices are still in use. The oldest still run with radio tubes, the others with transistors. Our showpiece is the device Biennophone Minitel 43 NB pictured above, which was introduced by the Swiss PTT in 1981 for the 50th anniversary of the telephone round-table. In the meantime it is one of the classics and is mentioned in articles about the history of the radio.

Unfortunately, in the year 1998 the telephone claim was discontinued with the introduction of ISDN, as the harmonics of the ISDN disturbed the signals of the telephone rounding. We would have had to replace all devices with new FM radios. Fortunately, we found a company that made us a device that transformed the FM signals of six transmitters into the conventional telegraph signal. This allows the historical devices to continue to be used today.
 
From the end of 2008, the digital radio DAB will be introduced in Switzerland, which will eventually replace FM. So we are again challenged: The goal is to be able to continue operating our historic radios in the ‘DAB and Internet age’.
