in accordance with Sec. 90.266. Except as provided in this part, 
licensees may not use these frequencies in the place of other 
operational circuits permitted by the Commission's Rules. Circuits 
operating on these frequencies may be used only for the following 
purposes:
    (i) Providing standby backup communications for circuits which have 
been disrupted and which directly affect the safety of life, property, 
or the national interest; or,
    (ii) Providing operational circuits during exploration.
    (2) Use of this frequency is limited to an amplitude modulation mode 
of operation.
    (3) This frequency is available for assignment only to stations
