A survey of radio recombination lines in the Galactic plane with longitude -32 Degree-Sign < l < +80 Degree-Sign and latitude b < {+-}3 Degree-Sign using Ooty Radio Telescope (ORT) at 328 MHz is reported. ORT observations were made using a New Digital Backend (NDB) recently added to the telescope. With the NDB ORT had a beam of 2.{sup 0}3 Multiplication-Sign 2.{sup 0}2 sec({delta}) and a passband of {approx}1 MHz in the spectral line mode. The above-mentioned Galactic region was divided into {approx}2 Degree-Sign Multiplication-Sign 2 Degree-Sign patches with the ORT beam pointed to the center. The ORT observations form a study of the distribution of extended low-density warm-ionized medium (ELDWIM) in the inner Galaxy using H271{alpha} RLs. By obtaining kinematical distances using V{sub LSR} of the H271{alpha} RLs, the distribution of ELDWIM clouds within the inner Galaxy has been deduced for the region given above.
