It was with sadness that I learned the news of Bob's passing. He was my mentor (as was Colin, VK5HI) and taught me many things about satellites.

There were times when we were in daily contact. Besides APRS, he left us many interesting satellite projects (PCSAT, PSAT, RAFT, MARS, SAPPHIRE, QIKOM...). I remember a great time when Henk, PA3GUO and I actively supported the ANDE mission. I thank Bob for his confidence in making me the command station of PCSAT and PSAT.

My sympathies go out to his family. Thank you for your life's work for Amateur Radio, Bob. Rest in peace.
