[quote=scwis]You have all the time in the world to stay logged on to this site for hours at a time, to receive email updates of new forum posts, to post in the forums, publish PDF files, and do the math to continue to share your opinions of what can’t be done.[/quote]Actually my posts show what can be done with certain equipment configurations and operating parameters. Some view that as my saying nothing else is possible, but numbers I post are only a benchmark for people to use or ignore, as they wish.
The reason I’m logged on so long is to give detailed responses to the topics posted here by others.
[quote]Not even the time to make some suggestions that might work in a theoretical ideal system with the standard assumptions in place (e.g., 50 ohms transmitter load impedance, 80 ohms RF impedance in the ground connection, 20 ohms ground loss – all taken from WA7CS RF Calculator Page, a source to which you so often refer)?[/quote]Anybody can download and run those programs. There are programs by that author (Reg Edwards, who is NOT WA7CS) to calculate the inductance, form factor, Q etc of a Part 15 coil, in fact. So that already is available if anybody wants them.
However the numbers posted in Neil’s quote of mine above, and most others I post, are based on my own NEC-2 analysis to determine the radiation efficiency of the antenna, and my own use of the FCC’s published groundwave propagation curves for medium wave.
