Thanks for the information William. Having slept on this matter, and mellowed a little, I have the following personal comments.... Is it time to draw a line under this copyright, IPR & Patent issue ?

I've just put my own Loop Preamp that I designed in 2006 in the Group's Photos section. It's a balanced preamp and is neither a Norton circuit nor a common-base circuit. I adapted it from an Ulrich

Good day all, I think the concept of the copyright and a patent are getting equal billing or confused here. A copyright is a form of protection for original works of authorship fixed in a tangible

Dave, Thanks for the input and advice Fraser

Andy's note seems appropriate to me. (It's called due dilgence.) Of course he is concerned...he designed the circuit and makes a living selling them. Whether one believes his work is copyright-able or

Thanks, it really never occured to me to click on the image (doh), but it indeed comes up large enough to (barely) make out the grainy diagram. (The power supply filter doesn't do as well.) (I was

I respectfully suggest you should try one of the Wellbrook antennas before expressing an opinion on how some other antenna would stack up against it. -- Jay

Hi All, I Have read and re read the veiled threat from Andy Ikin and it doesn't sit well with me. This is the first time a group to which I have belonged has been accused of attempting to commit an

Steve, I clicked on the diagram I think you're referring to and it loaded a second, larger version of the schematic. It was plenty large enough to read, assuming I knew how to read it. -- Jay

How does one obtain a larger or higher resolution circuit diagram for the WL1030 amplifier? The tiny diagram that you can download from the site is too small to make out anything in the picture, and

Hi Andy, et al Well, I believe anyone who is interested in learning how things work has become involved in 'reverse-engineering'. When I was a kid there were more carcasses of old radio's, clocks,

thanks for letting us know Partrick agree with your concerns likely the low non-inductive resistance across the loop to obtain the wide bandwidth is what some of us were missing so as to give reason

I am sure this antenna is quite nice but I know from long experience that a true resonant loop will out play and perform most any of these commercial designs... Why? Because with the commercial

Thanks for the excellent link C.B. It was most sad to read that the designer of this loop has passed on. The WL1030 looks a most interesting design. Now to source the parts, make the pcb and have a

To all interested in a 1 meter diameter active broadband loopantenna, in: http://wl1030.pa3ang.nl/content/ you will find all construction details. And you are free to use the design. You have to
