Moderator: Scotty Cowling, WA2DFI

Bio: Scotty was first licensed in 1967 and has been continuously active since that time. He is active while mobile on HF CW and on APRS. Scotty is an advisor for Explorer Post 599, a BSA affiliated ham club for teens in the Phoenix area. He has been involved in the openHPSDR project for the last 9 years, and is a TAPR Director and past TAPR Vice President. Scotty is also active in the production of openHPSDR components and other SDR projects.

9:15 to 9:25AM Introduction by Steve Bible, N7HPR, TAPR President

9:25 to 9:30AM The World According to PSR by Stana Horzepa, WA1LOU , PSR Editor

9:30 to 9:35AM Write for QST/QEX by Kai Siwiak KE4PT, QEX Editor

9:35 to 10:00AM . “SDR vs Legacy Radio” by Adam Farson, VA7OJ/AB4OJ

Abstract: SDR technology is rapidly displacing legacy radio architecture in the mil/gov, commercial and amateur radio sectors. Several new OEM's, as well as a strong open-source group, are building SDR transceivers and receivers rivaling and even surpassing legacy radio equipment. Established OEM's are transitioning from legacy to SDR. We will explore the relative merits of SDR and legacy radios and the issues peculiar to each type, from the Ham's perspective. Two architectures will be discussed: the legacy superhet with a DSP IF chain and the direct-sampling/digital up-converting SDR. It is assumed that the serious Ham will choose one or the other of these, or both.

Bios: Adam graduated from University of Cape Town, South Africa with a BSEE in 1963 and an MSEE 1971. He is a holder of US Extra Class and GROL, Canadian Advanced licenses. Adam retired in 1999 after a 35-year professional career in RF design for radio communications and at CERN followed by satellite and wireline telecom. He is now keeping busy with evaluation and testing of amateur transceivers and receivers, and with technical writing and presentations on related topics.

10:00 to 10:25AM “Collecting Solar Eclipse Data using SDR, plus a Low Noise VHF/UHF Synthesizer" by John Ackerman, N8UR

Abstract: (1) Using an SDR to collect data during the “Great American Eclipse” on August 21, 2017, and (2) a Versatile Low-Noise VHF/UHF Synthesizer.

Bio: John Ackermann, N8UR, has been a board member, officer, and project contributor to TAPR for over 25 years. His long-term interest is precise time and frequency measurement, and for the last several years he has also been involved in SDR development and application. John and wife Jody, KC8KDC, recently moved back home to Dayton after a seven-year relocation to Atlanta.

10:25 to 10:30AM “What is HamSCI?" by Nathaniel Frissell, W2NAF

Abstract: The Ham Radio Science Citizen Investigation (HamSCI) is an organization that allows professional researchers to collaborate with the amateur radio community in scientific investigations. HamSCI aims to advance scientific research and understanding through amateur radio activities, encourage the development of new technologies to support this research, and provide educational opportunities for the amateur community and the general public. This presentation will explains HamSCI’s goals, organization, and an overview of current projects, including the Solar Eclipse QSO Party, the Personal Space Weather Station, and Field Day Experiments.

Bio: Nathaniel Frissell, W2NAF, is a research professor with the New Jersey Institute of Technology Center for Solar-Terrestrial Research. Nathaniel’s interest in ionospheric science began in middle school when he was introduced to amateur radio through scouting. He earned his B.S. in Physics and Music Education from Montclair State University and his M.S. and Ph.D. in Electrical Engineering from the Virginia Tech SuperDARN Laboratory. His Ph.D. dissertation is entitled "Ionospheric Disturbances: Midlatitude Pi2 Magnetospheric ULF Pulsations and Medium Scale Traveling Ionospheric Disturbances.” Nathaniel is an Eagle Scout and remains and active scouter. He holds an Extra class amateur radio license and founded the Ham Radio Science Citizen Investigation (HamSCI) project. Nathaniel is a co-advisor to the NJIT Amateur Radio Club, K2MFF.


Joint TAPR/AMSAT Banquet Friday evening at Dayton.

Michelle Thompson, W5NYV, will present “It¹s just software, right?” She will survey the AMSAT Ground Terminal: Who, what, when, where, why, and how we¹re designing open source radio solutions for the next generation of AMSAT payloads.

Michelle is AMSAT¹s Team Leader for the design and execution of the AMSAT Ground Terminal. The goal is to create a “5 and Dime” (5 and 10 GHz) digital SDR transceiver that will support both voice and data modes, for both general QSOs and emergency communication, for the Phase 4B satellite and for future AMSAT projects. This is an effort to design an inexpensive ground terminal for amateurs that would cost tens of thousands of dollars commercially, for as much under $1,000 as we can get it.

A true renaissance woman, in addition to being an engineer and a licensed amateur radio operator, Michelle has worked for Qualcomm, attends Burning Man, and is a longtime DEFCON participant. She is also the lead for Organ Donor (an AI pipe organ). Her Phase 4B Weekly Ground Engineering Reports are fascinating reading.

Dinner tickets must be purchased in advance at the AMSAT Store.

No tickets will be sold at either the AMSAT or TAPR booths.
