Well, I'm still "kicking". I spent the last 14 months in a cave deep in the Colorado Rockies, but I'm starting to come out more often now. FWIW, I only saw your email via the direct route. I have not seen it via 50mhz at mailman.qth.net ... yet -- even tho' it was sent over seven hours ago. We'll see if _my_ email gets through the 50mhz reflector... 73 Jonesy -- Marvin L Jones | W3DHJ | W3DHJ | https://W3DHJ.net/ Pueblo, Colorado | @ | Jonesy | __ linux FreeBSD 38.238N 104.547W | jonz.net | DM78rf | 73 SK From kd7jyk at earthlink.net Tue May 18 13:06:13 2021 From: kd7jyk at earthlink.net (KD7JYK DM09) Date: Tue, 18 May 2021 10:06:13 -0700 Subject: [50mhz] Antenna In-Reply-To: <8o6o994-srs6-82p8-nspo-2554s5r1024@wbam.arg> References: <2AB6ADD87C92451F9D0F0BA27C32EEC4@HAMSHACK> <4C33E8A4.40300@kd4e.com> <015c01cb1e03$d5ffaff0$29a4f604@mainframe> <7BB23E6D3216408899DA4BB90ADF84C9@dell332028a83b> <014a01cb1e35$a336f920$78a5f604@mainframe> <49cd18ba-b356-bcc8-d6a0-7574eeb861e1@earthlink.net> <8o6o994-srs6-82p8-nspo-2554s5r1024@wbam.arg> Message-ID: > Well, I'm still "kicking".

The last message through the forum in my 50 MHz folder was dated 2010, the last messages being posts from you regarding antennas.

You're right!!! I guess the reflector is just running on auto-pilot. Maybe when Es picks up in this cycle, it'll get busy. But, then, maybe they all went to FT8/FT4/WSPR/etc. forums where they all brag about "heard" reports. 73 Jonesy -- Marvin L Jones | W3DHJ | W3DHJ | https://W3DHJ.net/ Pueblo, Colorado | @ | Jonesy | __ linux FreeBSD 38.238N 104.547W | jonz.net | DM78rf | 73 SK From ke5apj at earthlink.net Tue May 18 18:42:35 2021 From: ke5apj at earthlink.net (D.

A while ago he mentioned he was part of a TV documentary being made about the Hindenburg disaster and was interviewed in Hangar #1 at Lakehurst Naval Air Station in 2019. (Filming was later halted due to COVID19 but it has finally been finished.) Bob?s mother and uncle were in Lakehurst when the Hindenburg exploded on May 6, 1937. His uncle took film footage of the explosion using his father?s Kodak 8mm movie camera. Bob kept the original film which his parents preserved all these years. Authenticated and researched, it is now finally being made public, and will prove to be an eye opener. This spectacular artifact is what?s highlighted in this new PBS NOVA documentary. MAY 19 at 9:00 PM on PBS NOVA. (WHYY and PBS13) titled, ?Hindenburg; The New Evidence.? Check your local provider?s listing. Preview here: https://www.pbs.org/wgbh/nova/video/hindenburg-the-new-evidence/ LAKEHURST, NJ ? For more than 80 years, investigators have tried to figure out what caused the spark that led to the Hindenburg going up in flames as it prepared to land at Lakehurst Naval Air Station in 1937. On Wednesday, a new "Nova" documentary is set to air on PBS that digs into the question and offers some scientific insights. "Hindenburg: The New Evidence" is set to air at 9 p.m. Eastern on PBS, and will be available for streaming online, according to the network. The new look at the May 6, 1937, disaster was prompted by a conversation at the 80th anniversary commemoration outside Hangar One of the fire and crash that killed 35 people on board and one person on the ground. Dan Grossman, a renowned expert on airships including Hindenburg, was approached at the commemoration by Robert Schenck, a New Jersey resident whose uncle, Harold N. Schenck, had filmed the disaster. Though Harold Schenck tried to share his amateur film, (which shows the disaster from a different angle than the newsreel films) with government investigators at the time, it was largely overlooked, his nephew says in the "Nova" film. The "Nova" documentary not only shares the footage, which provided new clues to re-examine the cause of the explosion, but the scientific experiments that helped investigators come to a fresh understanding of what set off the fire. The original investigations into the Hindenburg crash concluded the fire was a result of leaking hydrogen ignited by a spark, but no one had been able to determine what caused the spark. Eyewitness accounts suggested the fire started near the tail of the airship, but supporting evidence was hard to find until the unseen Schenck footage was examined. Newsreel recordings of the disaster begin after the fire is well underway, and most physical evidence was destroyed immediately in the blaze. Grossman had the footage authenticated as part of the investigation. Then he and Jason O. Harris, a retired U.S. Air Force lieutenant colonel and commercial airline pilot trained in accident investigation, along with Konstantinos Giapis, a professor of chemical engineering at Caltech, examine clues provided by the Schenck footage to reach new theories about why and how the explosion happened the way it did. "Thanks to this stunning new footage, we were able to revive a cold case investigation surrounding one of the most iconic disasters of the 20th century," said Gary Tarpinian, the film's executive producer. ?This film not only reveals new insights into how this tragic event unfolded, but also illustrates the enormous scale of the disaster," said Kirk Wolfinger, the director. "The Hindenburg remains vivid in our collective memories all these years later because of the searing images and film of the explosion," said Chris Schmidt, the co-executive producer of "Nova." "We feel honored to share this new footage with the world and to bring the 'Nova' audience behind the scenes of this pivotal new investigation into the crash.?

Any way to sneak that loop into the attic, or maybe hang it from the ceiling? Put some dangly things on it, call it a mobile, like over a babies crib? How about a dipole made from twin lead, and making it look like an FM broadcast antenna, maybe set a junk FM radio under it to complete the look: https://www.ebay.com/itm/174086611896 Kurt From af5cc2 at gmail.com Sun May 23 02:17:40 2021 From: af5cc2 at gmail.com (John Geiger) Date: Sun, 23 May 2021 01:17:40 -0500 Subject: [50mhz] 6 meter yagi question Message-ID: If your mounting location for a 6 meter beam was less than optimal-on a roof tripod, maybe 25 feet above the ground, with the antenna being 3 feet or so above the roof of the house, would be there much advantage of going with a 5 or 6 element beam over a 3 element beam?
