       Subpart C-- Technical Standards and Operating Requirements
 
Sec. 5.111  General limitations on use.

    (a) The following transmission limitations are applicable to all 
classes of stations in the Experimental Radio Service:
    (1) Stations may make only such transmissions as are necessary and 
directly related to the conduct of the licensee's stated program of 
experimentation as specified in the application for license and the 
related station instrument of authorization, and as governed by the 
provisions of the rules and regulations contained in this part. All 
transmissions shall be limited to the minimum practical transmission 
time.
    (2) When transmitting, the licensee must use every precaution to 
ensure that the radio frequency energy emitted will not cause harmful 
interference to the services carried on by stations operating in 
accordance with the Table of Frequency Allocations of part 2 of this 
chapter and, further, that the power radiated is reduced to the lowest 
practical value consistent with the program of experimentation for which 
the station authorization is granted. If harmful interference to an 
established radio service develops, the licensee shall cease 
transmissions and such transmissions shall not be resumed until it is 
certain that harmful interference will not be caused.
    (b) If experimental stations are to be used to retransmit signals of 
any other station or to render any communications service to third 
parties, a full disclosure of this must be made in the application for 
license.
