D -- REQUEST FOR INFORMATION REGARDING SATELLITE UPLINKING SERVICES DUE 012599 POC Sandra Baxley, Contract Specialist, (404) 842-6881 This is a modification to the Request for Information regarding satellite uplinking services dated 12/14/98. The CBD submission number for the original announcement is 278768. This modification is being issued to include the following information: Satellite TRANSPONDERS must be CAPABLE OF PASSING A 36 MHz bandwidth for C-Band and A 36 MHz bandwidth or higher for Ku-Band. THE USE OF 27 MHZ KU-BAND transponders IS NOT allowed. The use of any transponder (either C-Band or KU-Band) that will not pass a minimum of 36 MHz will NOT deliver a standard one-volt peak-to-peak color video signal level to a consumer grade satellite receiver of any properly calibrated downlink site. Please discuss the availability of satellites WITH TRANSPONDERS THAT CAN PASS A BANDWIDTH OF 36 MHZ or higher and also address alternatives to achieve a quality transmission. This modification changes the response due date to 012599. Posted 01/05/99 (I-SN285231). (0005)
