Campus Radio Nürnberg was a university radio of the Georg-Simon-Ohm-Hochschule in Nürnberg . The aim was to test the possible fields of application of the Digital Radio Mondiale standard and shortwave at local radio level between 2003 and 2009 . Thus it served as an education and training radio .
history
At the beginning of 2003, a transmission system was installed on the building of the technical college to transmit on the frequencies of the CB radio . Initial attempts to transmit showed that the transmissions had a range of 2 to 25 kilometers , depending on the antenna position and radio weather .
Due to technical and financial problems, the duration of the Digital Radio Mondiale project, which was originally scheduled for one year, was delayed.
In the area of DRM, the Campus Radio Nuremberg dealt with the problems of constant mobile reception, which previously prevented unstable field strengths . With regard to the operation at 26,000 kHz, which has now been relocated to 26,012 kHz, the focus was on the investigation of the propagation conditions, especially due to overreaches such as at the sporadic E-layer as well as the influence of sunspots and interference at the local level.
Because of too much effort, broadcasting was finally completely outsourced to Dillberg . Thanks to the cooperation with the Bavarian Broadcasting Corporation and the district of Neumarkt in the Upper Palatinate , it was possible to continue broadcasting there on 26,000 kHz. During the operation there, the supply of the area of the city of Neumarkt in the Upper Palatinate was ensured within a radius of 8 to 10 kilometers. The project was finally discontinued on May 31, 2009. The result was new knowledge about the propagation conditions on 26 MHz at regional level and the confirmation of the possibility of compensating for local disturbances and interference as well as poor mobile reception.
technology
As a transmitter initially served one for the amateur radio operation conceived Collins - Transceiver Type 32S-3 with a maximum of 100 watts transmitter output power. This was modified for this purpose so that it emitted the carrier wave generated by a computer with 10 watts at 26,000 kHz. For this purpose, the signal was fed into a dipole antenna of the amateur radio station at the college.
On the new site in Dilberg, operations were continued with 100 W transmission power on a ground plane antenna. Due to the more exposed location at an altitude of 600 m. ü. NN. Half the transmission power of 50 watts was used for test purposes.
