Radio waves telegraph receiver

Dating

18 November 1938

In September 1895 a gunshot decreed the invention of one of the first wireless transmission apparatus in the world. The first code used for transmitting information by using the electromagnetic waves was the Morse one. This device allowed the reception of radio waves in Morse code, thus sequences of lines and dots that form letters or numbers, not the human voice.

The additional indications which integrate the items of the conservation's state have the following meaning: (?) = maybe complete; M = maintenance; P = partial; R = restored; D = used for teaching; NC = not checked; X = impossible to verify.

In order to avoid that instruments' cards without the english description text of the device be directly selected, I added a special filter with which only the complete cards are shown in the menu. Anyhow all the partial english instruments' cards (with instrument's dating, dimensions, state of conservation...) can always be seen even if they haven't the english description text. To read this uncomplete cards is sufficient to click, for example, on an instrument's picture or on the word "View" of the table column called "Card" every time they appear in the other pages of this database.
