[amsat-bb] HEO history question

Back in late 1997 or early 1998 I was using a Kenwood TR9130 on 2m SSB. One morning I was tuning from the FM to the SSB portion of the band, and heard a station just below 146mhz. I tuned them in, and it was a station from Wales! Obviously going thru a satellite as the 2 meter conditions weren't that good that morning. I am now wondering what satellite it probably was. Hearing it was enough to motivate me to eventually get into satellite operations-that took a few years though.

Anyways, what satellite was I probably hearing? I am guessing AO10 or AO13 but were they operational at that time?
