Adrift – Problem solving FS2 drift issues.

High altitude balloons are expected to drift, in the atmosphere. But Flying Squirrel #2 (FS2) has had some drifting problems of another kind. During construction as the FS2 flight electronics went from a breadboard prototype to final construction, a problem emerged. FS2 was not WSPRing clearly. In fact, it seemed to be more of a […]

FS7 – The Flying Squirrel #1 Flight controller software

The FS#1 flight controller is designed to measure basic weather information (Barometric Altitude, Air Pressure and Temperature) and relay that information periodically to the ground via radio telemetry using the FSQ protocol. Additionally, the flight controller conserves battery power by turning off the radio and weather sensor between transmissions.     In a nutshell the […]

Flying Squirrels #3 – Can you hear me now? – Building a transmitter

Now that I have a list of protocols and a general plan to transmit telemetry on the 20 meter Ham bands, how do I get “on the air”?  This post will describe the transmitter hardware for the telemetry system. Generating Radio Frequency – There is a board for that. After a lot of searching an […]
