9:30-9:50 KiwiSDR

Abstract:
The KiwiSDR is a self-contained open SW and HW SDR system which offers a very user friendly UI to this high performance RF processing system. It includes a 66 Msps 14 bit ADC RF system coupled to a FPGA which can support 4 or 8 simultaneous and completely independent receive sessions, each with over 100 dB dynamic range. The internal GPS subsystem delivers 50 ppb frequency accuracy, and the Kiwi can be easily connected to an inexpensive external GPSDO for state of the art frequency accuracy and stability. A Python library supported by the Kiwi author allows remote applications to control the Kiwi and extract and process the demodulated streams. As an example of that, I will describe the WSPR decoding program running on a Raspberry Pi at KPH which simultaneously decodes all 14 LF/MF/HF bands from 3 Kiwis during every 2 minute WSPR cycle. Live demos of the system will be available during the meeting.

Rob Robinett is CEO and Founder of Mystic Video, a Silicon Valley developer of professional TV broadcasting products. Previously I founded two other video compression equipment companies: Modulus Video, acquired by Motorola in 2007 and Skystream Networks acquired by Tandberg in 2004. After a 40 year hiatus I resumed my interest in amateur radio in 2017 with a particular interest in optimizing RF receiving systems. Last year I deployed SDR and WSPR receive systems at the historic KPH receive site at Point Reyes National Seashore (http:kphsdr.com:8073) and a second set of SDRs and WSPR receivers at a rural Maui location (http:kiwisdr.robinett.us:8073).

9:50-10:10 DRAWS: The Digital Radio Amateur Workstation.

Abstract:
Based on the Raspberry Pi with a Dual Radio Interface and Power Supply, DRAWS provides a complete HW and SW Solution for operating Digital Modes from HF thru VHF/UHF. DRAWS can operate Stand-A-Lone as well as a dedicated server or Remote Base.

10:10-10:30 Phase 4 Ground Adaptive Coding and Modulation

Abstract:
An accessible technical talk about how modern satellite communication links sense, react, and adapt to the radio environment. You will leave this talk with both the theory and understanding of an advanced wireless technique that you can then experiment with at home. Adaptive Coding and Modulation is used in Phase 4 Ground radios.
