1. Navtex.xls
is a spread sheet that i have made that lets you feed in your ships
present position and then will give you all the various navtex transmitters
within range. The options available are in the form of macros buttons
a)
If you click 518khz then it will filter out all the rest of the local
language tx's as well as the other 2 frequency tx's
b)
If you click all freq / all language button then it will give you all
the transmitters within range.
c)
If you click "click and specify range manually" then it will
give you stations within the range that you specify and not the range
specified by alrs. eg, on our run from the persian gulf to colombo,
we were unable to get any navtex stations within range, so if you want
to specify ranges in excess of the recommended ones then click and enter
the ranges manually........else leave the box without a tick.
If you want to view the table where all the stations are
then click on "NAVAREA 1" and all the rest of the navarea
headings and the hyperlink will take you to the table of transmitters.
The list of transmitters was last updated in june 2002
and i will do so again in december or early jan but so far it is very
accurate.
The ranges from the vessel to the tx's is a great circle
distance. |
