Box 838 « Hood River, Oregon 97031 * Tel (541) 386—1747 « Fax (541) 386—2124 March 15, 2000 Federal Communications Commission Experimental Radio Service PO Box 358320 Pittsburgh, PA 1521—5320 ANPC, under FAA contract (contract number DTFAOQ1—99—C—00054) continues to test and evaluate the Transponder Landing System as part of the system approval process. The system at The Dalles Municipal Airport (Dallesport WA) is key to engineering tests that support the FAA test process. Currently, the system is operating under authorization provided by an STA dated 2/9/00 (File #: 0047—EX—S$T—2000; Call Sign: WAIXGD; expires 8/9/00). Due to an updated analysis of the output EIRP, and analysis work by the FAA spectrum management office, ANPC is requesting changes to the authorized power levels per the information below. If a new STA is required, we request that it extend for a 180 day period to allow continued system testing. Attached is a copy of the current STA. All special conditions on the current STA are still applicable. Antenna patterns have been submitted with the previous request that led to the current STA, and are therefore not included herein. If more technical information is required, please call ANPC customer services manager Fred Conn at (541) 386—1747. The following is a summary of the frequency use requests: Location of Station Dallesport, WA NL 45—37—06 WL 121—10—00 Frequency Power(EIRP, dBm) Emission Designator Signal Name 108.35 32 6KOOA9W Localizer 333.95 40 300HAIN Glide Slope 1030.0 62.3 6MOOMID Interrogation 1090.0 49.3 6MOOMID System Calibration / BIT Thank you for your time and attention in this matter. %Z(@ Mark Zanmiller Director, hardware engineering ANPC—20065—FC—MZ
