Give the following information of person who can best handle inquiries pertaining to this application:   Last Name: Kean First Name: John Title: Senior Technologist Phone Number: 202-513-2476

Explanation

Please explain in the area below why an STA is necessary: he proposed testing will provide direct evaluation of the interference susceptibility of a particular set of C-Band receive-only earth terminals used by NPR. As discussed in Item 5, the testing would require the emission of low-power RF test signals in the vicinity of the receive terminal, which may require a STA.

Purpose of Operation

Please explain the purpose of operation:

Susceptibility Testing The test transmissions are requested to empirically determine the interference susceptibility of NPRs standard C-Band receive earth terminals with signals that are in-band or on frequencies immediately adjacent to the frequency band used for downlink. Direct measurement is needed to more accurately determine this performance, which is usally based on tests or estimates of individual components in the system (antenna directivity, LNB amplifier and filter performance, etc.), which together may differ from actual system performance.

Certification

Neither the applicant nor any other party to the application is subject to a denial of Federal benefits that includes FCC benefits pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. Section 862, because of a conviction for possession or distribution of a controlled substance. The applicant hereby waives any claim to the use of any particular frequency or electromagnetic spectrum as against the regulatory power of the United States because of the prvious use of the same, whether by license or otherwise, and requests authorization in accordance with this application. (See Section 304 of the Communications Act of 1934, as amended.) The applicant acknowledges that all statements made in this application and attached exhibits are considered material representations, and that all the exhibits part hereof and are incorporated herein as if set out in full in this application; undersigned certifies that all statements in this application are true, complete and correct to the best of his/her knowledge and belief and are made in good faith. Applicant certifies that construction of the station would NOT be an action which is likely to have a significant environmental effect. See the Commission's Rules, 47 CFR1.1301-1.1319.
