I just discovered that the USCG's Navtex frequency of 8416.5 has changed to 8415.6 kHz. I was using my old preset, which explains why I haven't been able to hear it for a while. Has anyone else noticed this? The EiBi listing still shows 8416.5, so at first I thought that my receiver was out of alignment, but both of my radios pick it up on the same new frequency.
