This first-hand account of the construction of a clandestine shortwave radio by British POWs in a Japanese camp in Singapore really reminds me of James Clavell's magnificent novel King Rat, my all-time favorite war-novel, which revolves grippingly around the construction, discovery and consequences of a hidden shortwave in the Changi camp (both Clavell and Ronald "St Trinian's" Searle were interned in this camp).
