The first name is H. (No kidding) and no, but I recall an RF Turbine. 73 H. "David G. Nagel" wrote in message ... Adam; Do you remember "Contra Polar Energy"? A lot of people fell for that, including yours truly. Dave N H. Adam Stevens, NQ5H wrote: I still can't believe anyone took this seriously. Steel wool must have slightly higher permeability than air, certainly no match for ferrites. 73 H. "Fred W4JLE" wrote in message ... Walt I went back through some old note books, according to my records I sent the letter to the editor in 1977. I know Roy says 93, but I have e-mails from that period and knew it had to be earlier. Does that match your recollection? "Walter Maxwell" wrote in message ... Thanks, Roy, I had forgetten where the stuff was published.

Perhaps your memory is better than mine on this issue. Walt, W2DU The results of your measurements were published in "Hints & Kinks" in September 1993 QST. According to the editorial comment accompanying it, you were prompted to make the measurements by Tom Rauch, W8JI, who had done some measurements which indicated that the steel wool balun was ineffective. The Hints & Kinks editor at the time, who had accepted both the original contribution by Curt Wilson, W0KKQ and yours, was Dave Newkirk, WJ1Z. Anyone interested in learning more about it should read the Hints & Kinks submissions and note Dave's added editiorial comments. Roy Lewallen, W7EL |

Back around 1962, I was working on the Syncom satellite program at Hughes
Aircraft. NASA wanted us to make some satellite transponder simulators so they could check out the ground stations. The plan was to take some of the 'less than perfect' hardware and package it up in a metal box. Unfortunately a lot of that stuff wasn't very stable, particularly the varactor multipliers. To make things worse, they used TWT amplifiers (in a separate box) followed by a 10 watt attenuator which brought the output back down to about the same level as the drive to the TWT. We ended up lining the boxes with steel wool along with a lot of metal tape to seal the seams, etc., and it did seem to help (a bit). I remember the steel-wool balun story and wondered at the time if perhaps it was merely absorbing some of the current on the outside of the coax. 73, Bob N7XY On Sun, 14 Aug 2005 23:34:48 -0400, Fred W4JLE wrote: Walt, I just went back and checked some old notes.

Works real good when mixed with black powder gun powder, home made
fireworks, Real colourful. Opps I think i aged myself. Seems to me some one tried to make a capacitor with it too, if my memory is working, again.

Don't recall if it was steel wool or a fine sandpaper But when you put up a brand new shiny antenna -- does it seem to work better, just like your car runs better after a wash and wax job (;-) Mine always gets wet in the rain that comes immediately after the wash job. ;^).... I recall that engines are supposed to deliver more power when water is sprayed to the air intake. Having washed you car, then driven it out in the rain, it may appear more nippy. Ian. -- |
