Best Contact
Give the following information of person who can best handle inquiries pertaining to this application:  
Last Name: Buhl
First Name: Dillon
Title: research scientist associate
Phone Number: 5129472480

Explanation
Please explain in the area below why an STA is necessary:
We would like to do full power bench and field testing of our VHF ice penetrating radar system. The radar system has fairly high peak power (low duty cycle) and will emit radiation.

Purpose of Operation
Please explain the purpose of operation:  Testing radar. The ice penetrating radar system has been successfully flown for airborne geophysical survey in Antarctica, Canada and Greenland. We need to do some full power (unattenuated) testing for EMI. The radar will be driven near full power through antennas to conduct experiments to evaluate various paths for radiated and conducted interference within components of the instrument suite.

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.
