Microwave facility cost, $380, CY 1984. Escalated to $454 

 FY 1987 using DRI GNP Implicit factors, MCA, page 12, col. B. 

 $454 times 43 channels = $19,522. 



Microwave facility cost, $380, CY 1984. Escalated to $454 

 FY 1987 using DRI GNP Implicit factors, MCA, page 12, col. B. 

 $454 times 13 channels = $5,902. 



UHF facility cost, $580, CY 1984. Escalated to $692 FY 1987, 

 using DRI GNP Implicit factors, MCA, page 12, col. B. 

 $692 times 13 = $8,996. 



Total foreign stations: $5,902 + $8,996 = $14,898.
