The radio field around the EGRET source 2EG 
shows, once the
galactic disk radiation has been properly subtracted, several sources, mainly
SNRs. Three of these remnants are reported for first time in this paper. The
only strong radio source within the 95% source location confidence contour of
2EG is the flat-spectrum, gravitational lensed QSO PKS
1830-211. Our observations clearly dismiss the possibility that one of
the previously unknown SNRs could be the radio counterpart of the
-ray source, strengthening the identification with the lensed
blazar proposed by Mattox et al. (1997). Additional support is
provided by the spectrum analysis of 2EG which presents a
steep index 
and by the presence of variability in
the -ray light curve. PKS 1830-211 seems to be, consequently, the
first well-resolved gravitational lensed object detected by EGRET.
