Super Pressure Floater on December 21st

|  Tom MatthewsNov 21   #374 

As a test prior to 2020 Hamfest, we are planing to fly a SBS - Scientific Balloon Solutions SBS-13 balloon in late December.  This balloon is roughly 3' x 7.5' laying flat on the table and is designed to lift up to a 20 gram payload to a float altitude of 41K - 43K feet.  That altitude gets us over air traffic and most weather.  This is the same balloon that has successfully circumnavigated the earth many times.See http://www.scientificballoonsolutions.com/  for more information.
Walter K5WH is working on ultra light super capacitor solar powered APRS / WSPR payload.  Here's information on a likely candidate:http://qrp-labs.com/lightaprs-w 

More details to follow as they become available.
To the Edge Again!
