Sec. 97.305  Authorized emission types.

    (a) An amateur station may transmit a CW emission on any frequency 
authorized to the control operator.
    (b) A station may transmit a test emission on any frequency 
authorized to the control operator for brief periods for experimental 
purposes, except that no pulse modulation emission may be transmitted on 
any frequency where pulse is not specifically authorized and no SS 
modulation emission may be transmitted on any frequency where SS is not 
specifically authorized.
    (c) A station may transmit the following emission types on the 
frequencies indicated, as authorized to the control operator, subject to 
the standards specified in Sec. 97.307(f) of this part.
