Haven't monitored RTTY Navtex transmissions on 518 kHz for quite awhile but did so over much of last evening. Pleasantly surprised to obtain a pair of messages decoded from Kodiak, AK during the 0750Z window from transmitter $12X and another pair of messages during the 0930Z window from transmitter $12J. 73, Garry, K3SIW, EN52ta, Elgin, IL
