In this video Patrick Stoddard WD9EWK shows that high power isn’t needed to work the satellites.
On Saturday, March 9. 2013, at 1636 UT at the Scottsdale Amateur Radio Club Hamfest in Tempe, Arizona (grid DM43al) he showed you can work F)-29 using just 5 watts from a FT-817ND to a handheld Elk 2m/70cm antenna. In fact he used two FT-817ND’s, one for transmit on 2m the other for receive on 70cm.
FO-29 was launched from the Tanegashima Space Center on August 17, 1996 into a 1,330 by 808 km orbit.
