SB SPACE @ ARL $ARLS009 ARLS009 AO-27 is back on the air! ZCZC AS09 QST de W1AW Space Bulletin 009 ARLS009 From ARRL Headquarters Newington, CT September 14, 2000 To all radio amateurs SB SPACE ARL ARLS009 ARLS009 AO-27 is back on the air! The AO-27 satellite has returned to analog Amateur Radio service. AO-27 ground controller Chuck Wyrick, KM4NZ, reports the satellite showed up on its first North American daylight pass on September 9. Wyrick advises operators to wait until they hear the satellite in analog mode--ie, no data being sent--before transmitting on the 145.850 MHz uplink frequency. AO-27's downlink is 436.797 MHz. Wyrick says the AO-27 analog FM repeater will be turned off for a few days at a time over the next few months so ground controllers can gather whole orbital data to verify the health of the satellite. AO-27's computer crashed July 31, and it took more than one attempt to reload the software and get the satellite up and running again. ''A lot of work has saved AO-27 for many more enjoyable amateur QSOs,'' Wyrick said in a posting to the AMSAT bulletin board. NNNN /EX
