FM Transmitter

For the Regional Radio Station we recommend a 2.000-watts stereo FM Transmitter from RVR,

Italy. The transmitter is 220/110 volts mains supplied via an APC UPS handling 5000 VA for

voltage safety. The transmitter is connected to an 8-bay omni-directional dipole broadcast antenna,

which raises the total output gain by 10,2 dB bringing the actual output signal to the equivalent of

10.000 Watts ERP. This system has the potential of reaching up to 100 km in radius if placed in a

tower of 60 to 100 metres in a topographically advantageous location. FM transmission is

depending on line-of–sight and that means that mountains, forests or buildings can block or

minimise the signal. Thus, a transmitter reaches far longer in a flat area than in a mountainous

region. For details of the transmission system, please refer to Chapter 4.

3.4.5 Upgrade to regional Media Centre

As is the case with the Community Radio Station, the Regional Station can be upgraded to afully

fledged Media Centre by adding extra equipment for Internet access and/or video recording and

editing. The choice of upgrade depends on the local needs and budgets, but a number of additional

computers (three to five) and a high-speed Internet access would be needed for the creation of a

community Internet Café.

With a limited additional investment of approximately 10.000 US$, the Regional radio Station

could also become a professional production facility for TV programmes and/or news items for

regional or national broadcast. An additional TV package is described in Chapter 4.
