Haven't looked for Navtex signals for awhile so tuned to 518 kHz over night. Nice to see a decode from Greenland station M in Simiutaq/Cape Farewell. Other area 4 stations decoded were A,C,E,G,H,N,P,R, and U. Messages from three area 4 stations out west also came through: H,Q, and W. 73, Garry, K3SIW, EN52ta, Elgin, IL
