             Subpart C_Operating Requirements and Procedures

 

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.
