According to a report filed on the Hearsat-L newsgroup, Ronald Rensen in the NL has uncovered several new UHF milsat downlinks in the IOR region. He gave a rough location for the emitter at 70E. Milsat monitoring ace Paul J. Marsh, contributor to: http://www.uhf-satcom.com - http://twitter.com/UHF_Satcom, believes these signals could well be from the Intelsat hosted payload aboard IS-22 at 72 deg East.
