SECTION VII
ITU MARITIME RADIOTELEPHONE
(PUBLIC CORRESPONDENCE) STATIONS
DESCRIPTION OF SERVICES
A worldwide network of public correspondence stations operating in
the high frequency band compatible with the Bendix/King KHF 950
make it possible to place personal or operational phone calls in flight.
You can be flying thousands of miles from land and reach one of
these stations by HF to place your call. These stations link aircraft
(and ships at sea) via HF with the regular land line phone system.
Easy access to the maritime radiotelephone network is provided by
the pilot programmable and pre-programmed features available
depending on whether you have the KCU 1051 Control Display Unit,
KCU 951 Control Display Unit, or KFS 594 Control Display Unit.
Access to the radiotelephone network is easy with the KCU 1051 and
the KFS 594 because ITU semi-duplex channels assigned to public
correspondence stations worldwide are set in the KCU 1051 and KFS
594 permanent memory.
Using KCU 1051, if you want to contact KMI on channel 401, on the
manual page, select chITU channel type and select channel 401.
The semi-duplex pair of frequencies associated with this channel are
pre-programmed in the KCU 1051 memory. Alternatively, the transmit
and receive frequencies of the ITU semi-duplex channels can be
stored in the 100 user-programmable channels for the KCU 1051.
This alternate method could be used to access a public correspon-
dence station that is operating on frequencies other than those pro-
grammed into the KCU 1051.
Using KFS 594, if you want to contact KMI on channel 401, just move
the MODE selector to the A3J mode position and select channel 401.
The semi-duplex pair of frequencies associated with this channel are
pre-programmed in the KFS 594 memory. Alternatively, the transmit
and receive frequencies of the ITU semi-duplex channels can be
stored in the 19 user-programmable channels for the KFS 594 . This
alternate method could be used to access a public correspondence
station that is operating on frequencies other than those programmed
into the KFS 594.
