Did you know?

Many of you are probably not aware of the fact that Non Directional Beacons in Canada have a way of remotely indicating the condition they're presently in. A normal NDB ident will consist of a morse code identifier, 600 ms space and a long dash, as in this example:
L NDB on 386 kHz - normal ident 

When the NDB is operating on the backup transmitter, the 600 ms space will be stretched to 1200 ms, as in this example:
L NDB on 386 kHz - backup ident 

When the NDB is operating on emergency power (diesel, batteries), the NDB will identify itself normally 3 times, followed by backup ident 3 times, followed by normal ident 3 times and so on...

Now you know.
