Suite 110 236 Massachusetts Avenue, N.E. Washington, D.C. 20002 Re: WDZXDQ Dear Ms. Dortch: Presently pending before the Commission is the above-referenced application filed by AT&T Corp. for renewal of an experimental license to test equipment in various frequency bands, including 2385-2390 MHz. The band 2385-2390 MHz is designated exclusively for flight test telemetry. Aerospace and Flight Test Radio Coordinating Council ("AFTRCC") is the Commission- and NTIA- recognized coordinator for Non-Government use of the shared GovemmentMon-Government flight test spectrum, such as the band 2385-2390 MHz. Flight testing is by definition a high-risk enterprise. The frequencies are used to transmit on a real-time basis data vital to the condition and performance of the aircraft under test. The data transmitted are vital to the safety of the aircrew and persons on the ground. Interference to the frequencies poses a risk to flight safety, and can not be permitted. According to AFTRCC's records, AT&T never requested AFTRCC coordination for use of these exclusive flight test frequencies. And in all events such coordination was never granted. Thus, the initial license should never have been granted. Accordingly, AFTRCC urges that, should the Commission be inclined to give any further consideration to this application, the flight test band 2385-2390 MHz be expressly excluded.
