Sec. 80.80  Operating controls for ship stations.

    (a) Each control point must be capable of:
    (1) Starting and discontinuing operation of the station;
    (2) Changing frequencies within the same sub-band;
    (3) Changing from transmission to reception and vice versa.
    (4) In the case of stations operating in the 156-162 MHz bands, 
reducing power output to one watt or less in accordance with 
Sec. 80.215(e).\1\
---------------------------------------------------------------------------

    \1\ Ship station transmitters, except hand-held portable 
transmitters, manufactured after January 21, 1987 must automatically 
reduce the carrier power to one watt or less when turned to the 
frequency 156.375 MHz or 156.650 MHz. All ship station tramsmitters, 
except hand-held portable transmitters, used after January 21, 1997, 
must automatically reduce power as described above. A manual override 
device must be provided which when held by the operator will permit full 
carrier power operation on channels 13 and 67. Hand-held portable 
transmitters must be capable of reducing power to one watt, but need not 
do so automatically.
---------------------------------------------------------------------------

    (b) Each ship station using telegraphy must be capable of changing 
from telegraph transmission to telegraph reception and vice versa 
without manual switching.
    (c) Each ship station using telephony must be capable of changing 
from transmission to reception and vice versa within two seconds 
excluding a change in operating radio channel.
    (d) During its hours of service, each ship station must be capable 
of:
    (1) Commencing operation within one minute;
    (2) Discontinuing all emission within five seconds after emission is 
no longer desired.
    (e) Each ship station using a multi-channel installation for 
telegraphy (except equipment intended for use only in emergencies on 
frequencies below 515 kHz) must be capable of changing from one radio 
channel to another within:
    (1) Five seconds if the channels are within the same sub-band; or
    (2) Fifteen seconds if the channels are not within the same sub-
band.
    (f) Each ship station and marine-utility station using a multi-
channel installation for telephony must be capable of changing from one 
radio channel to another within:
    (1) Five seconds within the band 1605-3500 kHz; or
    (2) Three seconds within the band 156-162 MHz.
    (g)(1) Any telegraphy transmitter constructed since January 1, 1952, 
that operates in the band 405-525 kHz with an output power in excess of 
250 watts must be capable of reducing the output power to 150 watts or 
less.
    (2) The requirement of paragraph (g)(1) of this section does not 
apply when there is available in the same station a transmitter capable 
of operation on the international calling frequency 500 kHz and at least 
one working frequency within the band 405-525 kHz, capable of being 
energized by a source of power other than an emergency power source and 
not capable of an output in excess of 100 watts when operated on such 
frequencies.
