Thanks for the Rad Lab link. It appears that all the volumes are available in PDF format. I'm downloading them all now. Having read a history of the Rad Lab and a biography of the man responsible, Alfred Loomis, it should be a lot of fun to read.
For those not aware of it, the Rad Lab existed in Tuxedo Park, NY as a personal project of Alfred Loomis before WW II. Loomis was also involved in building the cyclotron at Berkeley. Lui Alvarez made an off hand comment to Loomis one evening that if they couldn't get copper they could use aluminum. Alvarez was blow away the next morning when Loomis told him it was not possible to build the magnets with aluminum wire for any of the designs being discussed. Loomis had stayed up all night making the calculations.
Loomis invented LORAN in the shower after a conversation with a Brit who was visiting. They wanted to name it after him, but he declined so they came up with a phrase to match the acronym.
Loomis closed the Rad Lab at the end of the war because he didn't think the government should be involved in research except in exigent circumstances such as war.
