George is down with the Flu, so Mark “Smitty Halibut” Smith KR6ZY guest hosts this week.  We debrief on Winter Field Day and talk about the battery projects on KF7IJZ’s workbench and the antenna project on KR6ZY’s workbench.  Finally we share additional sessions from BayCon 2018.  First Pieter Noordhuis KK6VXV talks about developing software for working GOES Weather Satellites.  Finally, Tim Fairbairn AF6TF talks about Summits on the Air (SOTA).
