I regret to inform the satellite community that our good friend, who many of us relied on for advice, or a new grid square, passed away on Tuesday, April 19th at the age of 84. Not long ago I recall he earned the distinction of Grid Master and had been an active member of AMSAT for decades. He was instrumental in arranging for at least two ARISS contacts with Austin, TX schools and wrote an important paper on Doppler shift that has been referenced on countless occasions. Ron also was a strong advocate for the use of SDR equipment for satellite communications and had recently contributed, along with co-authors, a number of articles on related subjects to the AMSAT Journal. I am sure that he will be greatly missed by many of us. Donations in his name and memory can be made to any charity.
