> "I tell you, I've got to do more 10M activity. The band is hot these

> Jon Jones, N0JK (EM28) in Kansas writes "A strong winter Es opening

> Jon is a frequent contributor to this bulletin, and he also writes
> "The World Above 50 MHz" column for QST Magazine.
> 
> The site http://www.arrl.org/the-world-above-50-mhz gives some
> details about the column and a little bit of history, where it says
> it "has appeared in QST for more than 60 years, making it one of the
> longest running columns. It originated as 'On the Ultra Highs,'
> which debuted in December 1939 under the direction of Ed Tilton,
> W1HDQ."
> 
> While true the column has run for more than 60 years, currently it
> has run for over 75 years. It says that W1HDQ was the first
> columnist, and I've mentioned before that Ed was also the author of
> this weekly bulletin until 1991, when Ed became ill, and I offered
> to write the bulletin for one week. I've been at it ever since, and
> I expect that Ed was the original originator of this bulletin, but I
> can't find anyone who knows when it began. I first copied it on CW
> from W1AW in 1966, when I was a very young ham.
> 
> From time to time I've paged through my old QSTs from the 1950s and
> 1960s looking for a reference to the bulletin, but have found none.
> Maybe it is time to apply some modern search tools to the effort.

> And now we come to the end of the run. This weekend I am completing
> my thirty-second season in this same role, but this is the final
> year of this production, and my character doesn't appear in the
> brand new 2015 production. This began for me with a series of
> unlikely events in 1983 when Don Walter, W7NG recommended me for
> this role in a brand new Nutcracker with sets and costumes by
> children's book author and illustrator Maurice Sendak. It was a huge
> hit, and as many as 46 performances are done (but I am not in all of
> them) every December. The house holds an audience of 3,000 people.
> This became hugely popular, so now that this is ending, every
> performance has sold out. By noon the day after Thanksgiving, ticket
> sales for this final Nutcracker hit seven-million dollars.
> 
> Every Christmas Eve we perform an alternative version, The Nutty
> Nutcracker, with all kinds of gags and pratfalls, improvised and
> with no rehearsal. On December 25, 2013 this photo appeared in the

> as he is about to let go with a tremendous dramatic sneeze while
> facing the audience downstage center so that I can react and express
> annoyance. He held the can so it appeared that it all projected from
> his face.

> I will be sad after the final last performance, which begins at 2330
> UTC on Sunday, December 28. I am the only player remaining from the

> 2015. But I love this company so much that I may come back as a
> volunteer Kid Wrangler, herding the children from dressing rooms to
> the stage and back. I am sad, but not bitter. It has been an
> incredible run, far beyond what I ever could imagine!
