+ | ===== Mains operation ===== | ||
+ | The earliest radio telegraph equipment were operated with heater and plate batteries or were fed by fuel operated generators, later devices operated with mains power became standard. | ||
+ | The classic Swiss devices can be fed by a variety of mains voltages, usually setting the voltage selector on 220 V (or 250 V , since the nominal mains voltage is 230 V today) is the correct position. | ||
+ | |||
+ | Few sets of U.S. origin are equipped with their original mains transformer wired for 110 V, these must be operated from the mains in Switzerland (or Europe) with a 110/220 V transformer. Some of the sets were later converted by radio amateurs to the Swiss mains voltages of 220 Volt - always check the voltage before connecting to the mains outlet! |
