The SRF-39 is a portable AM/FM radio introduced in approximately 1992 by Sony.[1] 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.[2][3][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][4]
The SRF-39 was followed by the SRF-49 in 1997, the PSY-03 in 1999, and the SRF-59 in 2001. These radios are popular in the DXing community due to their sensitivity, selectivity and ferrite antennas.[2][1]
