About FO-29
FO-29 (Fuji-OSCAR 29, JAS-2) is a Japanese satellite built by the Japan Amateur Radio League and launched on 17 August 1996 on an H-II rocket from Tanegashima. Its V/u linear transponder made it one of the most useful SSB and CW satellites for decades.
The transponder is inverting: uplink 145.900–146.000 MHz, downlink 435.900–435.800 MHz, with a CW beacon on 435.795 MHz. Tune the lower end of the uplink to hear yourself at the upper end of the downlink, and use LSB up for USB down.
FO-29 does not run all the time: its batteries limit how long it stays on, and during eclipse seasons JARL switches the transponder on by command for scheduled periods. Check its AMSAT status before a pass. When it is on, its 800–1,300 km orbit gives passes of around 20 minutes and contacts of more than 3,000 km.
