The amateur radio community is sad by the loss of amateur radio legend Bob Heil K9EID. He is the founder of Heil Sound, who makes audio equipment that is used by the best musical artist around the world and also the first manufacture to be admitted to the Rock and Roll Hall of Fame. He was also on of the original hosts of Ham Nation. I could go on and write down all of his accomplishments but I would be typing here for a week.
I was very lucky to have met him in 2019 OzarkCon in Branson Missouri
We exchanged probably over 100 emails over the years with him giving me advice on radios and antennas and me entertaining him with jokes. I'm sure that he is in Heaven building coaxial resonant dipoles and hooking up a audio mixer and stage monitors to a HF radio.
Bob thank you for teaching us so much.

P.S. SK stands for Silent Key which in amateur radio lingo means that a amateur radio operator passed away.
