According to rumor, the Prairie Masker is modelled as always running, meaning that the OHP should be quieter than the average ship all the time.
However, in the standard database this is not modelled significantly and there is no jammer at all. The only thing on the OHP that could be confused with a jammer is the Nixie Torpedo Decoy or the chaff/flares.
FYI, Amizaur and I have made modelled the OHP has being actually quieter than other ships, so for all practical purposes, the jammer is taken into account in the next version of our mod.
