Amateur Satellite Frequency Coordination Request1
Amateur Satellite Frequency Coordination Request — Page 1 AMATEUR SATELLITE FREQUENCY COORDINATION REQUEST1 1. Amateur-satellite service. Amateur stations meet the requirements of the radio regulations2, RR 1.56. and 1.57. RR 1.56 amateur service: A radiocommunication service for the purpose of self- training, intercommunication and technical investigations carried out by amateurs, that is, by duly authorized [licensed] persons [individual natural people] interested in radio technique solely with a personal aim [for themselves] and without pecuniary interest [compensation]. (NOTE: Explanatory terms in brackets are not part of the treaty text.) RR 1.57 amateur-satellite service: A radiocommunication service using space stations on earth satellites for the same purposes as those of the amateur service. Before asking for help from IARU with frequency coordination in the amateur-satellite service, make sure that your proposed operation meets the treaty requirements. NOTE: “Without pecuniary interest” means that you may accept free will donations of goods and services, that is, with nothing required in return. You may not sell services or data to anyone for any reason. Ultimately, the decision of whether the proposed operation is appropriate for the amateur- satellite service rests with your country’s administration (your national telecommunication regulator). Therefore, before sending your frequency coordination request to IARU, we suggest that you consult with your administration to determine whether the amateur-satellite service or another radiocommunication service is appropriate for your operation. 2. Self coordination. For over 100 years, amateur radio operators have maintained an effective tradition of self-regulation. Amateurs are expected to coordinate their use of frequencies. -
The Am Broadcast Band
THE AM BROADCAST BAND While crystal sets are designed, built, and used for the AM broadcast band and shortwave bands, the vast majority of hobbyists in the US focus their activities on the AM band, defined by the FCC to span from 530 through 1,700 kHz. As of January 1, 2008, there were roughly 4,793 AM stations active on the band, and this number of stations hasn’t changed much over the last ten years. Power output assigned by license to these stations varies, from as little as 250 watts to a maximum of 50,000 watts. Format, i.e. the content broadcast by each station, varies. As noted in Figure 1, the concentration of AM stations assigned at each increment of 10 kHz in frequency varies across the band, numbering 25 at 540 kHz, averaging about 30 from 550 through 1200 kHz and about 65 from 1210 through 1600 kHz. Just a smattering of stations occupy segments from 1600-1700 kHz. Figure 2 displays the concentration per frequency for the 50 Kilowatt stations that operate day and night. These stations - often called clear-channel stations – can cover a wide area at night as their radio signals reflect off the ionosphere. During the day, local stations are those most often heard, as long-distant reflections off the ionosphere are reduced. Clearly, we can use these facts to improve our listening and logging activities. During the day is the best time to receive or log those stations that are within a given radius of our location. At night the clear-channel stations will dominate and we’ll tend to hear those whose antenna pattern (direction of transmission) and reflection pattern (for that day) off the ionosphere is aimed at our location. -

Chapter 2 DX Nets the Beginning Dxer Can Get a Good Jump on DXCC by Frequenting DX Nets
Activities 2 ne of the best things about this hobby we call Amateur Radio is its flexibility. In other words, Amateur Radio can be whatever you want it to be. Whether you are looking for relaxation, excitement, or a way O to stretch your mental (and physical) horizons, Amateur Radio can provide it. This chapter was written by Larry Kollar, KC4WZK. Let’s take a brief tour through the following topic areas: Awards — the individual and competitive pursuits that make up the tradition we call “paper chasing.” Contests — the challenge of on-the-air competition. Nets — both traffic nets, where amateurs pass messages on behalf of hams and nonhams, and the casual nets, where groups of people with common interests often meet on the air to swap equipment, anec- dotes and information. Ragchewing — meeting new friends on the air. Amateur Radio Education — Educating current and future hams brings in new blood (and revitalizes old blood!); educating our neighbors about ham radio is good for public relations and awareness. ARRL Field Organization — Amateur Radio in general, and the ARRL in particular, depend on the volunteer spirit. As part of the Field Organization, you can exercise your administrative, speaking and diplomatic skills in service of the amateur community. Emergency Communications — When disaster strikes, hams often have the only reliable means to communicate with the outside world. Practice and preparation are key to fulfilling this mission. DF (Direction Finding) — If you’ve ever wanted to know where a transmitter (hidden or otherwise) is located, you’ll find DFing is an enjoyable and useful skill.
