 While digging through some boxes that were in deep storage I found my Fullerphone and Fieldphone F. One of my eclectic areas of collecting is communications so allow me to share some pics and info regarding the Fullerphone. The Fullerphone was the first untappable communication systems (when using Morse) due to its incredible ability to work at currents as low as half a microamp! You could use a pair of conductors or the earth as the return but rather than bore everyone with a bunch of technical jargon such as Buzzer/Chopper, choke coils, and dual reversed rectifiers I'll post a link to the excellent wireless for the Warrior website so you can read further if so inclined.https://www.wftw.nl/fullerwi.pdf https://www.wftw.nl/Signal%20Training%20Vol.III,%20No.%2021.pdf  |
