AirNav: KSTL - St Louis Lambert International Airport - 278.3 and 351.9 listed as PRM - I believe the aircraft puts a 2nd radio receiver on 1 of these 2 freqs when doing simultaneous ops on parallel runways - aircraft listens for alerts from control tower - but no civilian freqs listed for PRM - ???
