I just got the message below a few minutes ago.
Bob was very well known in the t-hunting community, and helped out a number of times at the Yuma Hamfest with the antenna building clinic and subsequent training.
RIP Bob.

It is with a heavy heart that I must share that Bob, WB6JPI passed away last night. I don't have any further details at this time.
Bob was a true ham, always sharing his knowledge and lending a
helpful hand.
I will miss him very much.
RIP Bob.
Tom, K6VCR
