1268.703 ～ 1268.708 MHz の範囲で Uplink を試みてね！
ということです。(↓抜粋)

revision 1 - AO-51 schedule for September through earlyOctober 2010
Another note--when the L-band uplink is active, most users report a
better experience using a frequency tuned a few kHz "higher" than the
published frequency of 1268.700 MHz. Try something in the 1268.703 to
1268.708 MHz range...and experiement for best uplink!
