- power of at least 50 kilowatts and operate with directional antennas. The antennas are required to be designed and operated so that the radiated power in the maximum lobe toward the specific zone or area of reception intended to be served is at least ten times the average power from the antenna in the horizontal plane. See 47 C.F.R. §§ 73.751, 73.753. We observe that most of our HFBC licensees operate transmitters at either 100 kilowatts or 500 kilowatts. See 47 C.F.R. § 2.102(h)(3)(iii). This and other special provisions regarding non-Federal Government use of spectrum allocated to the fixed and land mobile services below 25 MHz were adopted shortly after WARC-79 and these provisions are codified at 47 C.F.R. § 2.102(h).

- in HFBC bands), which would allow international broadcast stations to provide FM-like sound quality to listeners in foreign countries. Nonetheless, we request comment on whether the DRM standard should be required for digital transmissions. We observe that broadcasting, unlike many other radiocommunication services, is a mass media service and that for such a service, standards are often useful. Currently, Section 73.751 of the Commission's Rules states that no international broadcast station will be authorized to install, or be licensed for operation of, transmitter equipment with a rated carrier power of less than 50 kilowatts (kW). The technical basis of this rule is that, given frequency congestion, an international broadcast station using DSB modulation needs to transmit with an output power of

- an administration replaces a DSB emission with an emission using digital or SSB modulation techniques, it should ensure that the level of interference is not greater than that caused by the original DSB emission. WRC-03 also invited administrations to encourage the inclusion of digital modulation capability in all new HFBC transmitters put into service after January 1, 2004. Currently, Section 73.751 of the Commission's Rules states that no international broadcast station will be authorized to install, or be licensed for operation of, transmitter equipment with a rated carrier power of less than 50 kW.
