Launch Parameters

Balloon and Payload

  • 36" Qualatex, unstretched
  • 32.4 gram payload
  • 2.4 grams free lift
  • Quarter-wave antenna.

Heat sealed neck.



Launch yesterday was a failure (crashed on train tracks).

Today will be using a Rev3 board that needed some slight cleanup after toasting (first ever).

Will launch at the pier with it hopefully not crashing into the water shortly after.

Less windy today. Also daytime and not raining.

Launched in high wind on Pier A. Was ok.

No signals received well after launch.

I didn't tune the crystal or system clock because it was working in my apt fine.

Change that for next time.

I am also using a quarter-wave antenna instead of half-wave.

Change? Ehhhhhhh it's already unwieldy. I'm hopeful half-wave works.

General Thoughts / Observations

I've had success launching WSPR before. Why isn't it working?

Is it the antenna?
