G22.7-0.2 and G25.5+0.0 are two sources possibly associated with TeV g-rays from HESS J1832-093 and HESS J1837-069, respectively. The source G22.7-0.2 is a known galactic supernova remnat (SNR) but the nature of G25.5+0.0 is less clear. The nature of the high-energy emission is not firmly determined yet. We report on the first dedicated full-synthesis imaging and pulsar searches in the region of both radio sources obtained from the Giant Metrewave Radio Telescope (GMRT) at 610 and 1280 MHz. The results presented here can help to discern between different origins for the g radiation associated with the TeV sources.
