Navtex transmissions - can they be received inland?

[franksingleton]

If you have good information about a station’s timing, please contact the NAVTEX coordination panel - c/o UKHO, Taunton. They will take notice and action. In the early 2000s Toulon was consistently late. Meteo France said that there was no problem and that their transmission were automatically on controlled by their clock. I persisted and gave specific examples of conflict with Valencia, Spain. Eventually the French had to admit (a rare event) that their station clock was 2 minutes slow.

We yachtsmen spend a great deal of time in an area, ships generally move through and are not nearly as aware as we are about such problems. So, by all means quote issues on YBW but please inform those that can take remedial action.

I'll add seconds to the timestamp and see how consistent it is over a few days, maybe even get a time stamp from the web somewhere to be sure.
Measuring things is such good fun

Having the reciever linked to a Raspberry Pi does seem to work really well though, view the messages on any device which can view a web page and plunk the lat and long into Opencpn with a single cut and paste.
