Kon-Tiki and the Gibson Girl



Back in July we shared a very nice video sent to us by Rupert G6HVY on the radios used by the Kon-Tiki expedition.  Many of us had questions about the device used by the intrepid radio operator to generate hydrogen gas (for the antenna balloon) while on the high seas.   Mike Herr WA6ARA supplied the answer:   1200 grams of Calcium Hydride crystals.  This was part of the WWII rescue  radio set CRT-3 (aka the Gibson Girl). 

Fair Radio Sales occasionally sells this intriguing device:

And here is great site with more details on the other antenna supports in the Gibson Girl set, including a ROCKET LAUNCHED KITE!
