11.2 National DSC frequencies for routine calls
When ship and coast stations call national stations for purposes that are not safety or distress
purposes, normally use the national frequencies allocated by the administrator prior to using the
international frequencies listed later.
3
The frequencies for Japan are as follows. Additionally, the
pair frequencies are used to make a call to the coast station.
Tx (kHz) Rx (kHz) Tx (kHz) Rx (kHz) Tx (kHz) Rx (kHz)
2169.00 8391.50 8431.50 18872.00 19682.50
4180.50 4218.00 12521.00 12623.00 22318.00 22410.00
6275.50 6326.50 16721.00 16844.00 25175.00 26103.00
11.3 International DSC frequencies for routine calls
The following international
4
frequencies are used when calling ship and coast stations via DSC if
the other station's nationality or the frequency they are watching is not know, except for safety or
distress calls. CH No. indicates channel numbers preprogrammed to this equipment.

-
The above frequencies can only be used when the DSC message category is
Routine.
- The above table lists the sending and receiving frequencies (duplex) when a
ship station calls a coast station.
- Routine calls between ship stations use 2177.00 kHz as simplex.
- Channels not listed in the table above (401/601/801/1201/1601) are the
frequencies listed earlier for distress and safety purposes.
- In the table above, channels 402/602/802/1202/1602/1801/2201/2501 should
be selected first when making routine DSC calls on international frequencies.
