Listened using 516.3 kHz USB LO last night for Navtex RTTY transmissions. Turned out to be a fairly active night. Copied area 4 stations A,B,C,E,F,G,M,N,P, and X, area 12 stations C,H,J, and W, and area 15 station D in Puerto Montt, Chile at 9414 km. For some reason area 4 station E in Savannah, GA was sending reverse polarity. 73, Garry, K3SIW, EN52ta, Elgin, IL
