We present results of a study of the radio emission field around the best estimate position of the low-latitude EGRET source 2EG J1834-2138. The identification of this γ-ray source with the gravitational lensed AGN PKS 1830-211 has been recently proposed by Mattox et al. (1997ApJ...481...95M). Additional support for this identification is provided here. Contamination produced by the diffuse disk emission has been removed from new radio images of the surrounding region of 2EG J1834-2138 allowing a determination of the fine radio structure. Several previously unnoticed supernova remnants have been found within a few degrees from the γ-ray source. However, the only strong radio source within the 95% source location confidence contour of 2EG J1834-2138 is PKS 1830-211. In addition, both spectrum and variability analysis of the EGRET data support the identification of both sources.
