                     Subpart A_AM Broadcast Stations
 
Sec.  73.28  Assignment of stations to channels.

    (a) The Commission will not make an AM station assignment that does 
not conform with international requirements and restrictions on spectrum 
use that the United States has accepted as a signatory to treaties, 
conventions, and other international agreements. See Sec.  73.1650 for a 
list of pertinent treaties, conventions and agreements, and Sec.  73.23 
for procedural provisions relating to compliance with them.
    (b) Engineering standards now in force domestically differ in some 
respects from those specified for international purposes. The 
engineering standards specified for international purposes (see Sec.  
73.1650, International Agreements) will be used to determine:
    (1) The extent to which interference might be caused by a proposed 
station in the United States to a station in another country; and
    (2) whether the United States should register an objection to any 
new or changed assignment notified by another country. The domestic 
standards in effect in the United States will be used to determine the 
extent to which interference exists or would exist from a foreign 
station where the value of such interference enters into a calculation 
of:

    (i) The service to be rendered by a proposed operation in the United 
States; or
    (ii) the permissible interfering signal from one station in the 
United States to another United States station.
