CRN satellite reception maintenance

enadmin, 2nd August 2012

As spring draws nearer we thought it important to provide some tips regarding CRN satellite reception.

Heavy rain and storm activity can affect the CRN service. During the most heavy downfalls it is possible for reception to become patchy or altogether lost. After the storm passes the service should return to normal without user intervention.

Should your station also suffer a blackout, CRN/CBF-provided satellite receivers should maintain their settings and restart themselves entirely as they were. In the event that this doesn't occur please check that your satellite receiver is set to audio channel 14. More involved issues will generally present themselves with flashing lights or codes on the display of the receiver, generally best checked against the equipment user manual. A copy of the code list for the common UEC receivers is available here. (110kb)

If a television is available at the station these can also be connected to the satellite receivers (RCA connector) to get more detailed error messages and general reception statistics which can greatly assist fault diagnosis. While a little red LED generally means BAD, more details are available through the on-screen display. It would be surprising if one of your volunteers didn't have an old telly gathering dust under the house that could be repurposed for this.

Finally, in times of good weather a little preventative maintenance will never hurt. If not weather-related most isolated reception issues can be put down to leaves and muck in dishes, spider webs over LNBs (see picture below!), loose cabling or the general deterioration of older equipment. Particularly in coastal regions rust will slowly work away over many years before the next storm sends a dish crashing from the roof.

We recommend having a professional satellite equipment installer come in to check over your equipment, easily found in your local yellow pages. Not only might your equipment be difficult or risky to access, there may be small cheap parts that can be easily replaced or repaired on the spot now rather waiting for a complete reception failure. Nor could it hurt to have your dish alignment checked - a few degrees make a difference.

An 8 part documentary series from NIM FM looking at the war on drugs in Australia and the rest of the world.


Presence in, and use of, online environments enabled by the Internet, especially continuously or repeatedly as opposed to leisurely or sporadically, has deep effects on the social, psychological and cultural aspects of Iranian youth. The aim of this article is to report on study findings into the social impacts of Internet use on young people in Iran. The findings generated through qualitative methods, including interviews with ten Iranian youth as well was direct observation and analysis of some Internet texts (in particular blogs), imply that the continuous presence of Iranians online – including interaction and information exchange with other users – has led them to form a modern Iranian identity.


Participatory research design appears as an attractive option in the study of community media organisations. It puts the generation of the research question, the design of data collection methods, and the analysis of the results in the hands of the researched. This approach can demystify the research process and can be an empowering experience. But, as I found out with my doctoral research, the researcher needs to carefully assess an organisation’s capacity to undertake do-it-yourself research, because, when things go wrong, this approach can also reveal conflicts within an organisation, as well as give rise to tension resulting from the divergent needs of the researcher and those of the researched. This paper describes the troubles that arose during fieldwork conducted at a community radio station, how these unexpected events forced a reformulation of the research question, and how this eventually led to an improved theoretical insight.
