Observations with the Energetic Gamma Ray Experiment Telescope (EGRET) on the Compton Observatory have shown that radio pulsar PSR B1706$-$44 is a source of pulsed high-energy gamma radiation. With additional data, new details of the gamma radiation are found: The light curve appears to consist of two closely-space peaks. There is little, if any, unpulsed emission. The energy spectrum does not show significant evidence of a spectral break in the few GeV range, unlike the other pulsars seen by EGRET. These results, especially when combined with the ROSAT X-Ray (Becker et al. IAU Circ. No. 5554) and TeV gamma-ray observations (Kifune et al. IAU Circ. No. 5905) of this source, emphasize the diversity seen among the known gamma-ray pulsars.
