Balloon and Payload
- 36" Qualatex, unstretched
- 32.2 gram payload
- 2.4 grams free lift
- Quarter-wave antenna.
Heat sealed neck.
Last launch had 2.4g free lift. Floated a few feet then went into the water.
The purpose of this flight is purely for testing the transmitter.
Therefore I am going to put in more free lift than usual to increase likelihood of good lift.
Launch worked. No signal.
Jesus christ, wtf is wrong.
What else is different?
Code changed since last. Now I power down the other radios, use ThinWire, SI5351 cut down.
Spacing of antenna attach points.
Quarter Wave antenna instead of half wave.
Is it just a transmission distance thing? Power?
Clearly it decodes in the apt. The signal is ok it seems.
General Thoughts / Observations
Going crazy trying to figure out why I'm failing constantly.
Continuing to consider what is different from these flights from past flights which worked.
