[Milsurplus] YE-YG/ZB presentation this coming Wednesday

[Jack Sullivan]

 The Stewart-Warner manual on the YG-1 gives the output power of the transmitter as 25 watts it was tuned to 246 MHz. Power consumption with heaters on & key down was 920 watts but this may have included the antenna synchro motors & the motors that turned the signal discs. I have both the manual, an incomplete set of the signal discs in its steel box & 2 examples of the R-1/ARR-1 along with all the airborne gear except for the big HF receiver as well as the very heavy DC power supply for the YG-1.
Admiral King was so impressed by this system in the late 1930s that he ordered all the carriers to be equipped with them. Did he have foreknowledge of the Japanese attack & the following Pacific carrier war? A lot of people believe that Rossevelt forced the Japanese to attack Pearl Harbor so that we could get the US into the war against the Germans because it looked likely that England would be invaded & the Nazis would wind up in British Canada.
Similar systems (YE?) were installed on many Pacific islands with airstrips but not Iwo Jima, likely because it was too close to the Japanese home islands & the signal could have been picked up by the enemy. Throughout the war they never were able to figure out how we found our way back to our carriers & emergency airstrips.
FWIW, my wife's late father was Admiral King's personal physician during WWII & is mentioned by name in King's memoir.
