Keynote address
Why science in Amateur Radio is important to drive the future
Speaker: Dr Nathaniel Frissell W2NAF
Dr Nathaniel Frissell, Ph.D., is an Associate Professor of Physics and Engineering at The University of Scranton. Dr. Frissell’s research interests include space weather and radio science, with a focus on traveling ionospheric disturbances and High Frequency (HF) radio propagation.

Telemetry via Repurposed WSPR for Amateur Radio Pico balloons as they travel around the World
Speaker: Stewart Clark ZS1WT
His paper describes why WSPR, developed by Joe Taylor, is used as a telemetry system for amateur radio Pico balloons carried globally by jet streams. Typical Pico balloon payload hardware is described along with the most common telemetry data and how it is encoded into valid WSPR packets. In conclusion, the science that can be extracted from this telemetry that is transmitted every 10 minutes.

Development of a contesting and DXing dashboard for the HamSCI personal space weather station.
Speaker: Owen J. Ruzanski KD3ALD, Computer Engineering Student, The University of Scranton, USA
The HamSCI Personal Space Weather Station is a multi-instrument system designed to measure space weather for both scientific research and amateur radio operations. The core of the PSWS is the RX-888/ KA9Q-radio WSPRDaemon-Grape High Frequency (HF) software-defined radio (SDR), capable of capturing and analysing signals across the 0.3-30 MHz range. While most PSWS development efforts thus far have focused on strictly scientific objectives, this project aims to make the data available and useful in real time for radio amateurs. The dashboard has a goal of enhancing real-time HF propagation assessments for Radio Amateurs.

EME on 23cm with a solar cooker.
Speaker: Derek Gravett ZS5Y
EME, call it EARTH Moon-Earth or moon bounce communication, it has a long history in Amateur Radio but for many decades required large expensive antenna arrays. I this presentation Derek introduces a simple easy way using a modified solar cooker as the antenna.

Technology in providing effective HAMNET emergency communication
Speaker: Brian Jacobs ZS6YZ Hamnet National Director
It is all about using the best technology available and having a plan B for when technology fails. As "Communication Specialists" we provide what works best and have a whole bag of tricks that we can fall back on when needed. Gone are the days of the Bakkie and Baofeng brigade.
The SARL Noise monitoring Project
Speaker: Anton Janovsky ZR6AIC
The SARL HF noise monitoring system takes a 12 x 1MHz bandwidth sample every 2 minutes using the RTL power utility and saves the measurements in a CVS file.
The 2-minute scheduling is done with a Crontab calling a script in the HF-noise directory. The RF samples are taken at a 1MHz bandwidth from 1MHz to 30MHz, therefore 29 of CVS files are cre-ated and get appended as the measurements are made
