16 May 2022 we have a single photo. This is a commercial installation at a water tank @580 meters ASL in Escondido, CA. It seemed a rather unique and poor way to run the feed line. Not good to have the feed line up against the antenna. And who knew the antenna would tilt? Probably a good idea to run a more substantial support. Why not just mount the antenna to the pole?
For May 9, 2022 we have pictures from space.
The folks down under are doing a lot of work with high altitude balloons. They recently did a launch and our fellow MNWiser, VK5JP, received and posted his pictures as he tracked the launch. If the payload looks familiar, they’re using a repurposed Visalia R41 Radiosonde, the same model that was featured in another “Picture of the Week” (below).

For April 25, 2022 we explore a low-cost laser diode.
This week we have the ultimate T-hunt – a weather balloon that has been to the edge of space.
