47    <p>It is astonishing to see the incredible pace at which the development of
48       broadcasting systems took place. Beginning with very simple devices using
49       crystals for demodulation the technology matured very fast and resulted
50       in the design and development of high performance transmitters and receivers
51       employing super heterodyning and the like.
52       This paved the way from simple crystal receivers which required special
53       skills to operate to everyday radios which were easy to operate and soon
54       could be found in nearly every household. A process which took a mere 15
55       years from its first steps to near perfection.
56       This development is reflected in the appearance of the devices as well. While
57       the first receivers were of a very technical design, later devices turned into
58       wonderful pieces of furniture, fitting neatly into the average household and
59       denying the fact that the receiver itself was a rather complicated piece of
60       equipment. This page shows some selected examples from the collection of the
61       museum which contains about 150 different receivers.

64<!--
65      <p>The short time between the moderate launch of broadcasting in the early 1920s and its perfection is amazing. The era of broadcasting began in Germany in 1923, at first with very limited reception quality. 15 years later the quality of reception was almost perfect. At the beginning the apparatures had a very technical design (exactly like today), but since the 30s the radio apparatures changed to partially attractive pieces of furniture. Chosen examples from the museum-holding (150 pieces) for both kinds are shown on this page.</p>

70          <p class="bildtext">Receiver made by Signalbau Huth (model E72):
71            This is an example of a cheap
72            receiver made in 1928. It was one of the first models which could
73            be connected to the mains thus eliminating the bulky anode batteries
74            requires by previous generations of receivers.
75            The sound quality of this receiver is quite limited and the horn
76            loudspeaker makes for a sound which one would expect from a tin can.</p>

81         <p class="bildtext">Wealthy people could afford a <b>Telefunken W9</b>
82           (shown in the picture on the left) which was available during the
83           same time frame. Equipped with an Acrophon loudspeaker it featured
84           a rich sound although with very limited bass. In addition to this
85           the receiver was quite sensible and could even receive stations
86           far away while the cheap model above was limited to the reception
87           of local broadcast stations.</p>

91      <p>The following pictures show some receivers of outstanding design
92         and outstanding technical properties. Apart from these the
93         museum's collection contains a lot of different receivers
94         covering all stages of the development of public radio
95         broadcasting.
96         These receivers include crystal radios, battery powered receivers
97         from the 1920s, a 'Luxus Super' (1930s) as well as the first postwar
98         receiver equipped with motorized search functionality and remote
99         control by cable, the SABA Freiburg 3D. The sound of this receiver
100         is so rich and impressive that even young people are faszinated and
101         admire this 50 year old technical miracle.</p>
102
103<!--
104      <p>The next two pictures show two apparatures that point out themselves optically and also technically, but the picture gallery could be continued without stopping.
105      <br />Many other curiosities can be admired in the museum, an audio experience is possible in every epoch: detectors, batterie-receivers (1920s), "Luxus-Super" (1930s) and at the end the first postwar receivers with motor-channel search and cable-remote control: SABA Freiburg 3D. The sound of this milestone with 5 built-in loudspeakers is so impressing that even CD-spoiled kids would stand wondering in front of this nearly 50-years old apparature.
106      <br />All in all you see how broadcasting was two or three generations ago and how fast the aparatures developed.</p>

124            1956 and shown above, is another outstanding piece of equipment.
125            It is a so called "Kofferradio" so it can be carried around and
126            it features even an integrated recordplayer - forseeing the
127            development of modern multipurpose receiver/CD-player combinations</p>

130          A rapid leap in time to the youngest model in the museal collection: The portable receiver from Metz with built-in gramophone. Of course the apparature, built 1956, still uses tubes. Youth would have been able to hear their "Elvis Presley"-records in the swimming pool if the radio were much more cheaper.-->
