Next to my patch there's a 150ft (50m) deep well that has dried up and the owner now intends to fill it in. He doesn't mind me dropping a few copper wires down it before he does so. Question: is thi
The type of environment is an essential part of the equation and so results in different environments are particularly of interest. This is exactly the crux of the matter. Mathematically, for a give
That would be a pity......... What, the demise of LF? Don't worry, it's the same annual prediction Mal has been making since six months after the 136kHz band was first opened.
There is no other mode currently in use that suits radio amateur type activity when considering bandwidth and transfer of information. Dogmatic assertion. Numbers, please!
More or less like the Schrödinger's cat in his famous <A HREF="http://www.npl.washington.edu/npl/int_rep/tiqm/TI_fig_09.html">GedankenExperiment</A> Having just attempted a physical realisation
And RTTY. And other digital modes. Of course, it's also MF rather than LF, where a transmitting antenna of a given size is eight times more efficient than at 2200m, and where there's only about a th
Any time one of my employer's broadcast transmitters would emit no sidebands, they always called me to go to the site and fix it, day or night. I wish I had known of Mr Walker's ideas sooner. Then we
It's not the initial transmission that commits the offense. It's the "acknowledgement" which is the problem; not because it's on a different frequency, but because it constitutes communication with

In reply to: I do not think there is a "true" SWR meter which can work by measuring things at only one point on a transmission line. SWR is a ratio and can only be indicated by making a set up which
Anyone plagued by a slow dialup connection may find this line-art version of the schematic not as pretty as John's, but about 7 times quicker to obtain: http://lwca.org/miscimg/exciter4.gif Fascinati
