The radio counterparts of the two persistent soft gamma‐ray sources in the galactic center region consist of compact sources at the center of double sided jets. The southern jet of 1E1740.7‐2942 appears to have been brightening during the last 1.4 years. This 3‐sigma level illumination implies that 1E1740.7‐2942 cannot be further away from the Sun than 17 kpc. If this brightening is associated to pairs of electrons and positrons produced during the γ‐ray annihilation event observed in October 1990, the particles are moving at ∼0.9c and will reach the outer lobes at the tip of the jets by the end of 1994. The compact radio source associated to GRS1758‐258 shows variations that are correlated with the drastic changes observed in the hard X‐rays. The compact source is connected with the extended lobes by curved jets that suggest ejections along changing directions. The nature of 1E1740.7‐2942 and GRS1758‐258 remains an open question, since no optical/infrared counterparts have been found associated to the compact radio sources.
