Wiretapping the Japanese Consulate, 1941

From Ghosts of Honolulu: A Japanese Spy, A Japanese American Spy Hunter, and the Untold Story of Pearl Harbor, by Mark Harmon and Leon Carroll, Jr. (Harper Select, 2023), Kindle pp. 59-60:

Warrant Officer Theodore “Ted” Emanuel didn’t join the Navy to be an undercover operative. His job as chief ships clerk is dedicated to keeping internal records, reports and correspondence. But now that he’s assigned to the 14th Naval District Intelligence Office, Emanuel is capturing another nation’s communications in yet another undercover assignment.

Today he’s on the streets of Honolulu dressed as a telephone repairman, unhurriedly working on the junction box near 1742 Nuuanu Avenue—the Japanese Consulate. As SAC Shivers is working on getting clearance from his FBI bosses to bug the consulate phones, Captain Hart goes ahead and just does it.

The hardest part of setting up a wiretap is knowing the right circuits to target, but in this case that’s easy. After that, it’s as simple as scraping the insulation from a segment of the two wires required to make a telephone circuit. A receiver is attached to the exposed portions with metal clips and extension wires. This is known as “cutting in” on a telephone circuit and can be done at a streetside phone junction box.

Emanuel finishes up and casually drives away. The taps he’s placed cover half a dozen of the consulate’s telephone lines. It’s a tightly compartmentalized operation. The calls, about fifty a day, will be translated and summarized at the Young Hotel by Denzel Carr, the master linguist. When he doesn’t have the time, he’ll rely on Douglas Wada to handle the workload.

The US Navy has some ears inside the consulate. Now it’s up to the staff inside to make an indiscreet phone call.
