SRF-39
The SRF-39 is a portable AM/FM radio made by Sony.[when?] It uses a single AA battery, as its analog electronics draw very little current. It was one of the first radios to use the CXA1129 30-pin integrated circuit, which later was responsible for the SRF-39's sensitive and selective performance.[1]
A variant of the SRF-39, the SRF-39FP, has a transparent case, designed to thwart contraband concealment. The radio often appears on the commissary lists of U.S. federal prisons, hence the "FP" suffix.[2] Both are popular in the DXing community partly for their generous recessed area for the tuning thumbwheel, 0-10 log strip, and guard chain.[3][4]
