OMG so sorry to hear this and in recent days I'd feared we'd have to read this message. Frank seemed to be posting the occasional comment and leaving some "Likes" here and there until just as recently as a few days ago, so I'm hoping he didn't have prolonged suffering. I certainly hope he realized until the end how much genuite warmth and prayers and good thoughts were coming from members of this RD community.
I always appreciated his political viewpoints and occasional snarky comment. When I first signed onto RadioDiscussions, he was the first to "like" one of my comments and welcome me. I never realized until I read his bio here that he had a PhD EE. He probably had enough knowledge and smarts to run rings around many on here who were less learned or informed, yet he never did. That alone shows his humility. RIP, Frank!
