Hello Mark,
I found this on internet about NAVTEX,
--------------------------
Frequency of operation
The NAVTEX system has been allocated three broadcast frequencies:
518 kHz - the main NAVTEX channel
490 kHz - used for broadcasts in local languages (ie: non-English)
4209.5 kHz - allocated for NAVTEX broadcasts in tropical areas - not
widely used at the moment.
All broadcasts from stations within the same NAVAREA must be coordinated
on a time sharing basis to eliminate interference.
In addition, power outputs from each station are adjusted to control the
range of each broadcast. This is particularly important during night-time
hours, as Medium Frequencies always travel further after dark.
