As you probably read at Gunter's etc., P360/PAN is a rather "secret" satellite with little info online. Always close to Yahsat 1B at 47.6°, for eavesdropping maybe. You may well be receiving Yahsat instead that also uses the military Ka-band.
The Satellite Encyclopedia says for P360/PAN: "Has carriers on 20.298, 20.402 & 20.700 GHz."
