Splash! Worked perfectly but we overshot the island! Drats!
See the track: http://aprs.org/balloons.html
We did not calculate the slow descent of a small water bottle only weighing
80g even without a chute. Only a 30’ streamer. The payload came down no
faster than it went up. So even though the cut worked at the Burn
Longitude, the descent overshot the island.

A small (2 party balloon) payload sending FM CW on 433.72 +/- MHz may be
heard within a few dozen miles of Annapolis Maryland around Noon on Wed.
It sends LAT/LON/ALT using a modified CW and a KeyFob 10mw FM transmitter.
The balloon will only go to 5000’ and wont have a range beyond 50 miles or
See details: http://aprs.org/balloons.html
You will see local APRS bulletins from the chase team, but You wont see the
position on APRS unless someone has time to take the decoded LAT/LON/ALT in
CW and enter them as an object.
