<br />b) Limitations:
<br />1) Tlie use of frequencies in this
<br />and is on a shared basis with the
<br />_ran-A ladionavigation system and is
<br />subject to cancellation or revision, in
<br />whole Of in part, by order of the
<br />Commission, without hearing, whenever
<br />the Commission iliall determine such
<br />action is necessary in view of the pri
<br />ority of the Loran-A radionavigation
<br />system. The use of these frequencies by
<br />amateur stations shall not cause harmful
<br />interference to Loran A system. If an
<br />amateur station causes such inter
<br />ference, operation on the frequencies
<br />involved must cease if so directed by the
<br />Commission.
<br />2) Operation shall be limited to
<br />(the subbands and input powers in
<br />wattt shown on page IS1).
<br />3) Where, In adjacent regions or
<br />subregions, a band of frequencies is
<br />allocated to different services of the
<br />same category, the basic principle is the
<br />equality of right to operate. Accord
<br />ingly, the stations of each service in one
<br />region or subregion must operate so as
<br />not to cause harmful interference to
<br />services in Ae other regions or sub-
<br />regions (No. 117, the Radio Reg
<br />ulations, Geneva, 1959).
<br />4) 3900-4000 kHz and
<br />71»o-7300 kHz are not available in the
<br />following U.S. possessions: Baker,
<br />Canton, Enderbury, Guam, Howland,
<br />Jarvis, Palmyra, American Samoa and
<br />Wake Islands.
<br />5) Amateur stations shall not
<br />cause interference to the Government
<br />radiolocation service.
<br />6) Not available in those por
<br />tions of Texas and New Mexico
<br />bounded by laUtude 33*24' N., and
<br />31*53' N., and longitude 105 40 W.
<br />; and 106*40' W. between the hours 0500
<br />and 1800 local time, Monday through
<br />Friday, except to sUtions authorized to
<br />operate in an organized civil-deferise
<br />network when civil-defense emergencies
<br />exist or when arrangements have been
<br />made with the Commission engineer in
<br />charge at Dallas, Texas, and the Area
<br />Frequency Coordinator at White Sands,
<br />New Mexico, for drills at speciHc dates
<br />and times.
<br />7) In the following areas the d.c.
<br />plate Input power to the final trans
<br />mitter suge shall not exceed 50 watts,
<br />except when authorized by the appro
<br />priate Commission engineer in charge
<br />and the appropriate military area fre
<br />quency coordinator.
<br />i) Those portions of Texas
<br />and New Mexico bounded by latitude
<br />33*24' N., 33*53' N., and longitude
<br />105*40'W. and 106*40'W.
<br />ii) Tlie stale of Florida, in
<br />cluding the Key West area and the areas
<br />enclosed within «fcles^ ^ 200-mile
<br />radius centered at 28 21 N., 80 43 W.
<br />and 30*30' N., 86*30 W.
<br />iii) The stale of Arizona.
<br />iv) Those portions of Cal
<br />ifornia and Nevada south of latitude
<br />37*10' N. and the area within a
<br />200-mile radius of 34*09' N., 119 11
<br />W.
<br />8) No protection in the band
<br />2400-2450 MHz is afforded from inter
<br />ference due to the operation of in
<br />dustrial, scicntinc and medical devices
<br />on 2450 MHz.
<br />9) No protection in the band
<br />5725-5875 is afforded from interference
<br />due to the operation of industrial,
<br />scientific and medical devices on 5800
<br />u u ..10) No protection in the band
<br />24.00-24.25 GHz is afforded from inter
<br />ference due to the operation of in
<br />dustrial, scientific and medical devices
<br />on 24.125 GHz.
<br />11) The use of A3 and F3 in this
<br />band is limited to amateur radio stations
<br />located outside Region 2.
<br />12) Amateur stations shall not
<br />cause interference to the Fixed-Satellite
<br />Service operating in the band
<br />3400-3500 MHz.
<br />13) The frequency 4383.8 kHz,
<br />maximum power 150 watts, may be
<br />used by any station authorized under
<br />this part to communicate with any
<br />other station authorized in the state of
<br />Alaska for emergency comiriunications.
<br />No airborne operations will be per
<br />mitted on this frequency. Additionally,
<br />all stations operating on this frequency
<br />must be located in or within 50 nautical
<br />iniles of the state of Alaska.
<br />c) The following transnutting fre
<br />quency bands end the associated emis
<br />sion authorized in paragraph (a) of this
<br />section are available for repeater sta
<br />tions, including both input (receiving)
<br />and output (transmitting):
