I had previously reported that Bill McArthur KC5ACR was very active on 2M FM from the International Space Station (ISS) using the ISS callsign NA1SS. Bill took up the challenge of completing WAS and WAC (and accomplished it). The high point for me was working NA1SS on Dec 5, 2005.
Bill was at the Dayton Hamvention this year and did a presentation on his experience with ham radio on the ISS. I also had the opportunity to meet Bill later in the day and thank him for energizing the ham radio community via his ARISS radio operating. We chatted briefly and I managed to get a photo of the two of us together.
