AggieSat 4 8 April 2014 Helen Reed Dear Helen I have discussed your request with my team. They have raised some concerns about the hue bandwidth of 406 kHz on 70 cm. We have decided to coordinate a frequency with the understanding that if any interference complaints are received from amateur stations that you switch of the transmission. We have coordinated the following frequencies: Downlink 436,250 MHz Uplink 145,980 MHz The above frequencies have been coordinated with the understanding that you have agreed to the IARU terms of reference for the use of amateur service spectrum for experimental purpose. Please advise us the launch dates once it is known. Although we have avoided coordinating frequencies which have already be coordinated for other known satellites on the same mission, it remains your responsibility to check for any possible conflict and advise us accordingly Please also confirm the name and full contact details of the person who will control the operation of AggieSat 4 after launch after launch. Please note that all frequencies in the amateur satellite service are shared frequencies. We have attempted to make the best possible selection for your project. Please also read the attached documents about controlling satellites. While coordinating the frequencies noted above, we also note that use of frequencies as described in your request for frequency coordination appears inconsistent with numbers 1.56 and 1.57 of the ITU radio regulations. 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]. (NOTE1: Explanatory terms in brackets are not part of the treaty text.),

(NOTE2: “ without pecuniary interest” means that you may accept free will donations of goods and services, that is, with nothing required in return. However, you may not accept money or other compensation for services or data provided to anyone for any reason.) 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. We strongly suggest consulting with your administration (telecommunication regulator) to determine if the amateur-satellite service or another radiocommunication service is appropriate for your operation. The decision of whether the proposed operation is appropriate for the amateur-satellite service rests entirely with your administration. We encourage you to share this letter with them. Best wishes for a successful project.
