Moderator: Scotty Cowling, WA2DFI
Scotty has been involved in the openHPSDR project for the last 12 years,
is a TAPR Director and current TAPR Vice President. Scotty is also
active in the production of other SDR components. He is a co-founder of
iQuadLabs, LLC, a supplier of openHPSDR systems and other Software
Defined Radio components. He currently works at Zephyr Engineering, Inc,
a computer consulting company that specializes in FPGA design and SDR

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

DRAWS: The Digital Radio Amateur Workstation.
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.

Phase 4 Ground Adaptive Coding and Modulation
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.
