Auction No. 61 will include 10 AMTS licenses in a specialized system of public coast stations in the 217/219 MHz band. A complete list of licenses for Auction No. 61 and their descriptions is provided in Attachment A of Public Notice DA 05-1047. The AMTSAs are based on, and composed of one or more of, the U.S. Department of Commerce’s 172 Economic Areas (EAs). In addition, the Commission treats Puerto Rico, the United States Virgin Islands, and the Gulf of Mexico as EA-like areas. Each AMTSA also includes the adjacent waters under the jurisdiction of the United States.
The following table describes the licenses that will be auctioned in each of the AMTSAs:
Block Frequency Bands (MHz) Total Bandwidth Pairing Geographic Area Type No. of Licenses
A 217.5 – 218.0 / 219.5 – 220.0 1 MHz 2 x 500 kHz AMTSA 9
B 217.0 – 217.5 / 219.0 – 219.5 1 MHz 2 x 500 kHz AMTSA 1
Note: The above table displays the band edges of spectrum blocks A and B using the twenty 25 kHz channels that comprise each block as listed in 47 C.F.R. § 80.385(a)(2). It should be noted that pursuant to 47 C.F.R. § 80.481, licensees are not required to use 25 kHz channelization and may choose any channelization scheme; however, regardless of the channelization scheme used, emissions at these band edges must be attenuated within the limitation that would be required under 47 C.F.R. § 80.211 if the licensee were using 25 kHz channels.
For Auction No. 61, licenses are not available in each spectrum block in every market. See Attachment A of Public Notice DA 05-1047 for a complete listing of the licenses to be offered.
