[ARC5] Seeking Extinct Wire

[kgordon2006]

You are wrong, Mike. Many of us are definitely interested. I am VERY interested!Thanks for making this series of posts available to us all.Ken W7EKBSent via the Samsung Galaxy S21 5G, an AT&T 5G smartphone

I note from the photo that the iron wires of the band appear to be twisted together into a cable configuration? I had read that the wires were not wrapped around each other, as the twist would caused the EM field inindividual wires to phase-cancel (like a twisted pair)<but rather layered to act like transformer laminations (thus the insulation)  Have you tried yours for function?  The one I have is a home-brew which came with steel wires that were twisted togetherinto a cable and painted with some kind of gray paint.  The coils and magnets are good, as are the lo-Z headphones, but the unit has no output, unless one stuffs volts of RFinto it, so that what one hears is just non-linear high-level leakage.The only thing I can see which looks "off"is the wires.  This one is a "demonstrator"which has a hand crank on the side. I mean to install a properclockwork, but not until it is functional.I had this crazy idea of trying to extrapolate the real, practical sensitivity of the "Maggie" used on the RMS Titanic, because I had some doubts about some of the claimsmade for receiving the ship's distress calls far inland, or even at modest coastal stations.But then I found the ship antenna technical specifications: a center-fed Marconi "T" 160 feet tall, with four "top hat" capacitive-loading horizontal wires 400 feetlong, the other capacitor plate  (ground plane) a zillion tons of steel floating in thousands of miles of salt-water. So... OK.  You probably could have heard them had McBride sparked a 12-volt battery across the antenna.But I still want to get this "Maggie" to work.TNX OM ES 73 DE Dave AB5SOn 5/30/2025 7:31 AM, Mike Feher wrote:Dave – I believe the originals were spot welded.Virus-free.www.avast.com
