Hi all

The Dave VE3KCL / QRP Labs WSPR High Altitude Balloon is over US and heading for a circumnavigation, we hope! Now on its 19th day, having traveled a total of over 36,000km (22,000 miles), cruising at an altitude of almost 11,000m (36,000 feet). Current location is DM48DA (Utah, US) and ground speed 62 knots (71 mph, 115 kph). See attached map of the path, and see http://qrp-labs.com/flights/s18 for live tracking and further information and photos.

Hi all

Hi all

After 20 days flight, Dave VE3KCL's QRP Labs Balloon S11 has completed a circumnavigation. See tracking at http://www.qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s11.html

Hi all

Dave VE3KCL launched his S-9 balloon yesterday. It uses a QRP Labs QRSS/WSPR transmitter (http://qrp-labs.com/ultimate3/u3s.html) with about 16mW power output on 30m band, using WSPR for tracking. See http://qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s9.html for live map tracking, photos and more details. Dave's transmitter, antenna, batteries and solar cells weigh only 23g in total!

Hi all,

Dave VE3KCL's Balloon S-7 with QRP Labs kits and firmware onboard for tracking, was launched 11-Mar-2016 13:00 UT. It is now mid-Atlantic, making very fast progress East.

Hi

On 24-Sep-2015 Dave VE3KCL launched a balloon from near Toronto (in fact two hydrogen-filled foil "party" balloons tied together) carrying a 35g payload. The balloon is currently travelling East, about to leave the US East coast. It is cruising at around 8,000m.

The electronics payload Dave built has a GPS, battery, solar panels, QRP Labs Si5351A Synthesiser module, and Arduino Nano (for low weight) that runs the QRP Labs Ultimate3S QRSS/WSPR transmitter firmware, but a slightly modified version.
