Current balloon flight - http://qrp-labs.com/flights/u3s17.html

Home brew 2/6m and 70cm antennas down for repair -

Fun experiementing with satellite antennas 432 and 2m -

New website for balloon payload design - http://radio-signals.com/forum/

Most of my time lately is spent with WSPR balloon experiments.Here are the basic details -




My first fabrication using mylar film was a learning experience.My son holds the 6ft diameter balloon while in the background I make the hydrogen.This balloon flew for around 13 hours at a max altitude of 35k ft and 30 gram APRS payload (by KD2EAT).I thank Don Piccard for his early support in my projects and providing me with the mylar test material -


Tools used for flight prediction -






99.9% of my radio activity is 20/30m WSPR and JT9 using the call SWLNXZ RX only on a Yaesu FT897D and simple 6-80m dipole.

Excellent results using this method - http://www.hamuniverse.com/balun.html




Many other concepts followed as seen here on this site (selection on left of page) -



Remote10 meter solar powered beacon 28.228 mhz CW FN02wj,Caneadea,NY 65 miles South of my home QTH.

Beacon operates from 6 volts from a pair of 12v / 32ah deep cycle batteries (parallel) using a charge controller 12/24/48v .Solar panels are 24v @ 75w each in parallel.

RF output was last measured around 250mw but may vary as the beacon was intended for 12 volts for around 2-3w.Using a 6 volt adapter to prevent over heating of the beacon.

Antenna is a vertical fiberglass tuned for 10m meter band.
