WORLDWIDE LISTING OF PUBLIC CORRESPONDENCE
STATIONS
Besides the four domestic stations previously presented, there have
been hundreds of maritime radiotelephone (public correspondence)
stations authorized for operation around the world. The two listings
which follow may help the operator to utilize some of the stations’ ser-
vices. The first listing provides the receive and transmit frequencies
for each of the ITU maritime radiotelephone channels. The second
listing gives an alphabetical listing by country of each of the maritime
radiotelephone stations and the ITU channel numbers assigned to
them.
Note: When using the KCU 951 Control Display Unit, it will first be
necessary to determine which ITU channel number will be used from
the second listing, and then refer to the first listing to obtain the
appropriate frequencies for semi-duplex operation. The KCU 951
should be placed in the USB mode. When using the KCU 1051
Control Display Unit, the ITU channel number may be used directly
when the channel type is set for chITU. When using the KFS 594
Control Display Unit, the ITU channel number may be used directly
with the MODE selector in the A3J position.
Note: The stations and ITU channels provided in the worldwide list-
ings are those which have been authorized for operation. This does
not necessarily indicate that each of these stations is presently active
or that it is using all ITU channels assigned to it. This listing should be
used as a guide only. It is highly recommended that the operator
make prior arrangements with these stations before attempting con-
tact to determine language used, rate and billing structure, actual
channels used, times in operation and other essential data.
