This morning, at 0751-0755 UT I picked up data bursts (that sound like signals from a modem) on the 143.625 MHz voice link from ISS. A few words were spoken during the pass, but the rest of the time was devoted to these data bursts. Do these come from the"Orbital Communications Adapter", a lap-top-based system mentioned on Florida Today's web pages? Sven Grahn
