Hi Raimo,

Normally a Coast Station has an MMSI number which begins with "00" (e.g. 002300230, Turku Radio).

Detecting a Coast Station is usually straightforward, you look at the first 2 digits of the MMSI and if they are "00" you have found a Coast Station.

This is the behaviour in YaDD.

There are, however, a number of shore-based establishments which have been allocated MMSI numbers normally used for Ships - these DO NOT begin "00", such as "Sailor Examiner 219015591".

YaDD cannot detect these as Coast Stations, as the only mechanism written into YaDD for detecting a Coast Station is to identify the "00" at the beginning of the MMSI.

YaDDNet, the online database, has been configured to allow a second list of "Special Coast Stations", I add each new "special" MMSI when we discover them.

Each message sent to YaDDNet is inspected and the MMSI checked against the list of "Special Coast Stations" to detect these unusual stations.

The current list of "Special" Coast Stations - which use Ship Station MMSI numbers is:

211204590,D,Jade Hochschule DH6000,53.24195,8.466548

412000412,CHN,Tianjin Seaman School,39.03144,117.6483

One "real" Coast Station is on that list : 237673000,GRC,Piraeus JRCC, but most of them are training colleges, who simply use a Ship MMSI on their Shore Based equipment.

In the DSC List group we have decided to treat these as Coast Stations, since they are in fixed locations on land.
