     S 97.303 Frequency sharing requirements.
     The following is a summary of the frequency sharing 
requirements that apply to amateur station transmissions on the 
frequency bands specified in S 97.301 of this Part. (For each ITU 
Region, each frequency band allocated to the amateur service is 
designated as either a secondary service or a primary service. A 
station in a secondary service must not cause harmful 
interference to, and must accept interference from, stations in a 
primary service. See SS 2.105 and 2.106 of the FCC Rules, United 
States Table of Frequency Allocations for complete requirements.)
     (a) Where, in adjacent ITU Regions or Subregions, a band of 
frequencies is allocated to different services of the same 
category, the basic principle is the equality of right to 
operate. The stations of each service in one region must operate 
so as not to cause harmful interference to services in the other 
Regions or Subregions. (See ITU Radio Regulations, No. 346 
(Geneva, 1979).)
     (b) No amateur station transmitting in the 1900-2000 kHz 
segment, the 1.25 m band, the 70 cm band, the 33 cm band, the 13 
cm band, the 9 cm band, the 5 cm band, the 3 cm band, the 24.05-
24.24 GHz segment, the 76-81 GHz segment, the 144-149 GHz segment 
and the 241-248 GHz segment shall cause harmful interference to, 
nor is protected from interference due to the operation of, the 
Government radiolocation service.
     (c) No amateur station transmitting in the 1900-2000 kHz 
segment, the 3 cm band, the 76-81 GHz segment, the 144-149 GHz 
segment and the 241-248 GHz segment shall cause harmful 
interference to, nor is protected from interference due to the 
operation of, stations in the non-Government radiolocation 
service.
     (d) No amateur station transmitting in the 30 meter band 
shall cause harmful interference to stations authorized by other 
nations in the fixed service. The licensee of the amateur station 
must make all necessary adjustments, including termination of 
transmissions, if harmful interference is caused.
     (e) The 1.25 m band is allocated to the amateur, fixed and 
mobile services in the United States on a co-primary basis. The 
basic principle that applies is the equality of right to operate. 
Amateur, fixed and mobile stations must operate so as not to 
cause harmful interference to each other.
     (f) In the 70 cm band:
     (1) No amateur station shall transmit from north of Line A 
in the 420-430 MHz segment.
     (2) The 420-430 MHz segment is allocated to the amateur 
service in the United States on a secondary basis, and is 
allocated in the fixed and mobile (except aeronautical mobile) 
services in the International Table of allocations on a primary 
basis. No amateur station transmitting in this band shall cause 
harmful interference to, nor is protected from interference due 
to the operation of, stations authorized by other nations in the 
fixed and mobile (except aeronautical mobile) services.
     (3) The 430-440 MHz segment is allocated to the amateur 
service on a secondary basis in ITU Regions 2 and 3. No amateur 
station transmitting in this band in ITU Regions 2 and 3 shall 
cause harmful interference to, nor is protected from interference 
due to the operation of, stations authorized by other nations in 
the radiolocation service. In ITU Region 1, the 430-440 MHz 
segment is allocated to the amateur service on a co-primary basis 
with the radiolocation service. As between these two services in 
this band in ITU Region 1, the basic principle that applies is 
the equality of right to operate. Amateur stations authorized by 
the United States and radiolocation stations authorized by other 
nations in ITU Region 1 shall operate so as not to cause harmful 
interference to each other.
     (4) No amateur station transmitting in the 449.5-450 MHz 
segment shall cause interference to, nor is protected from 
interference due to the operation of stations in, the space 
operation service and the space research service or Government or 
non-Government stations for space telecommand.
     (g) In the 33 cm band:
     (1) No amateur station shall transmit from within the States 
of Colorado and Wyoming, bounded on the south by latitude 39\o/ 
N, on the north by latitude 42\o/ N, on the east by longitude 
105\o/ W, and on the west by longitude 180\o/ W. This band is 
allocated on a secondary basis to the amateur service subject to 
not causing harmful interference to, and not receiving protection 
from any interference due to the operation of, industrial, 
scientific and medical devices, automatic vehicle monitoring 
systems or Government stations authorized in this band.
     (2) No amateur station shall transmit from those portions of 
the States of Texas and New Mexico bounded on the south by 
latitude 31\o/ 41' N, on the north by latitude 34\o/ 30'N, on the 
east by longitude 104\o/ 11' W, and on the west by longitude 
107\o/ 30'W.
     (h) No amateur station transmitting in the 23 cm band, the 3 
cm band, the 24.05-24.25 GHz segment, the 76-81 GHz segment, the 
144-149 GHz segment and the 241-248 GHz segment shall cause 
harmful interference to, nor is protected from interference due 
to the operation of, stations authorized by other nations in the 
radiolocation service.
