January 13, 2019 To All RADIO AMATEURS BID: $ANS-013.01 AMSAT 50th Anniversary Awards Program The Radio Amateur Satellite Corporation (as AMSAT is officially known) was formed March 3, 1969 as a not-for-profit, 501(c)(3) educational organization chartered in the District of Columbia. Since its founding, AMSAT has designed, constructed, and, with the added assistance of international government and commercial agencies, successfully launched, 20 Amateur Radio satellites into Earth orbit. To help celebrate 50 years of Keeping Amateur Radio in Space, AMSAT is proud to announce the AMSAT 50th Anniversary Awards Program. Throughout 2019, your satellite and HF QSOs can help you achieve one of these special awards: + 50th Anniversary AMSAT OSCAR Satellite Communications Achievement Award + 50th Anniversary AMSAT Satellite Friends of 50 Award + AMSAT on HF 50th Anniversary Award 50th Anniversary AMSAT OSCAR Satellite Communications Achievement Award (Limited Edition) Unlike the AMSAT Satellite Communications Achievement Award, the 50th Anniversary AMSAT Satellite Communications Achievement Award will be issued on one of the original goldenrod paper stock certificates and signed by AMSAT's founding President, Perry Klein, K3TJE (now W3PK). With only 20 original certificates available, this award will certainly become a collector's item. The first 20 applicants to successfully submit 20 confirmed, qualifying contacts on any satellite will receive this award. A qualifying contact is defined as the establishment of two-way communication on any amateur radio satellite, with another station in a U.S. state, Canadian call area, or DXCC entity, no two of which may be the same. + All contacts must be made between March 03, 2019 00:00 UTC and December 31, 2019 23:59 UTC. + A U.S. state shall mean any state of the United States and the District of Columbia. + The 14 Canadian call areas are VE1 - Nova Scotia, VE2 - Quebec, VE3 - Ontario, VE4 - Manitoba, VE5 - Saskatchewan, VE6 - Alberta, VE7 - British Columbia, VE8 - Northwest Territories, VE9 - New Brunswick, VO1 - Newfoundland, VO2 - Labrador, VY0 - Nunavut, VY1 - Yukon, VY2 - Prince Edward Island. + Only one qualifying contact is allowed for each U.S. state, Canadian call area, and DXCC entity. + Qualifying contacts may not be counted for multiple types of entities. As an example, a QSO with Alaska counts as an additional state or DXCC entity, not both. + Contacts must be made from same location, or from locations, no two of which are more than 50 miles (80 kilometers) apart. + Previous recipients of the AMSAT Satellite Communications Achievement Award, may apply for the 50th Anniversary AMSAT Satellite Communications Achievement Award. The cost for this award is $25, plus postage. Certificates will be mailed upon receipt of payment. Certificates will be sequentially numbered.

It is life size, and based on the latest Fox-1 engineering drawings for highest fidelity in design and appearance. The model is printed in color on heavy stock paper, includes all components, and the instructions are carefully prepared to allow for easy assembly requiring scissors, glue etc. Depending on experience, assembly will take approximately 10+ hours. The complete model will be a perfect addition to any satellite operator's shack, and a chance to show visitors what is being done by AMSAT today. All proceeds will go to supporting AMSAT's satellite projects. Price is $40 + shipping. https://www.amsat.org/product/fox-1-cubesat-model/ [ANS thanks the AMSAT Office for the above information] --------------------------------------------------------------------- CubeSat Airborne Science Payload Standard As part of a new initiative, the Cal Poly CubeSat Lab is working with NASA Ames Research Center to prototype a standardized mounting system for testing CubeSat-based systems on aircraft (incl. UAVs) and balloons. We are seeking collaborators interested in airborne testing payloads, components, or complete systems, that could provide use- cases and assist in defining interface requirements. This Project has the potential to allow for expanded opportunities for payload development and testing. We would like your input as we design and develop this system and have put together a google form with a ten short questions that would help us derive our system requirements in the coming weeks. For more information visit: https://tinyurl.com/ANS013-AirborneScience [ANS thanks Cal Poly CubeSat Lab via Dave Pignatelli for the above information] --------------------------------------------------------------------- UWE-4 CubeSat frequency change request approved After two weeks in orbit, UWE-4 is in very good shape. The batteries are fully charged, the temperatures of the batteries, the outside panels and the MCU are all lying in the expected range. It has been observed that the battery temperatures are slightly rising around 8:45 am, when the downlink of this measurement took place. After the early orbit phase, we are looking forward to some interesting experiments with the attitude determination sensors and the propulsion system. Unfortunately, our uplink success rate is very poor, which currently prevents these experiments. In the precursor mission UWE-3, it was found that the reason for this is very likely a substantial noise floor at the used frequency range. For this reason, we filed a request for the change of our radio frequency to 435.600 MHz with IARU, which has already been approved. January 10, we will started the procedure to change the frequency of UWE-4. So if you want to track UWE-4, please adjust your center frequency accordingly. We already started the procedure to change the frequency on UWE-4, so during the next days it may happen that you can also still receive a signal on our old frequency. Additionally, we have been assigned NORAD ID 43880 in the meantime. A tool in order to upload the received UWE-4 telemetry directly into our groundstation database is a work in progress and will be shared with you as soon as we have tested it thoroughly. Until then, we would be very grateful, if you'd forward your UWE-4 telemetry files to uwe4(a)informatik.uni-wuerzburg.de. [ANS thanks the The UWE-4 Team via Trevor M5AKA for the above information.] --------------------------------------------------------------------- HamSCI 2019 Workshop Set for March in Cleveland, Call for Papers Issued The 2019 HamSCI Workshop will take place March 22 - 23 at Case Western Reserve University (CWRU) in Cleveland, Ohio, in association with the CWRU Amateur Radio Club (W8EDU). Registration is now open, and papers are invited. "We are especially looking for speakers with presentations showing analysis of ionospheric observations, ideas and proposals for the design of the Personal Space Weather Station and instrumentation for the 2024 eclipse," HamSCI's Nathaniel Frissell, W2NAF, said. "We will also accept other presentations related to Amateur Radio and science." If you would like to present, email your abstract to hamsci(a)hamsci.org by February 10, 2019. The theme for this year's conference will be "Ionospheric Effects and Sensing," including the use of Amateur Radio techniques to characterize and study ionospheric phenomena such as traveling ionospheric disturbances, sporadic E, response to solar flares, geomagnetic storms, the 2024 total solar eclipse, and other space weather events. Discussion will include continued development of the HamSCI Personal Space Weather Station and integration of Amateur Radio into the collegiate curriculum. Featured speakers will include well-known Amateur Radio author Ward Silver, N0AX, propagation specialist Carl Luetzelschwab, K9LA, and Larisa Goncharenko, who will talk on Space Science for Ham Radio Operators.

Satellite ground station build project - video 1
by John Brier 12 Jan '19

12 Jan '19

HI folks, I am building a Yaesu G-5500, M2 LEO pack, Icom IC-910H based ground station. Nothing exotic at all but I thought it would be cool to make simple videos/livestreams as I progress through the process. Here is the first video that gives background on this process that started one year ago. https://www.youtube.com/watch?v=9Hz4bWVByDw I'll be adding all the videos to the following playlist. In there there is also an older video I did when I first bought some of the necessary equipment: https://www.youtube.com/playlist?list=PLdgdw8eApVJ_h669wjn40IBRnrB9U-gYl 73, John Brier KG4AKV

Pass Recording - Sony ICD-PX370
by Frank Karnauskas 12 Jan '19

12 Jan '19

I just brought my new PX370 home and anxious to try it. I am sure the audio output from a handheld is safe to run into the external mic jack. But has anyone run the audio from a mobile rig such as a Kenwood D-710 into it? I am thinking maybe I should put a pad between that radio and the recorder. Any suggestions or experiences with this? 73, Frank FRANK W. KARNAUSKAS, N1UW ARRL MINNESOTA AFFILIATED CLUB COORDINATOR AMSAT NEWS SERVICE ROTATING EDITOR 1402 SUMMIT SHORES DR.

Protecting SDR
by Kevin Zari 12 Jan '19

12 Jan '19

For those of you with an SDR dongle, for example the Funcube Pro +, how do you protect it from not being damaged by TX energy? I’m thinking of hooking mine up to the 70cm antenna in my M2 LEO pack while I TX on the 2m antenna and was afraid I’d overload the SDR. I see folks using them for their RX on linear birds, so I’m just wondering how you have them hooked up. Thanks in advance for your advice. -Kevin (KK4YEL) ----- The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence.
