Not quite sure what you're trying to say with the bulk of your comment - you seem to be mixing terms yourself e.g. SNR/SND/SDR - but I'm pretty sure this Owen Duffy is the guy who used to be in the radio engineering dept at Australia's OTC (and, if I recall correctly, after OTC was sold/disbanded, ended up at the Telstra Research Labs?). I only spoke with him a few times (my area at Telecom/Telstra had some minor responsibility for a couple of weird and wonderful HF & VHF links/systems), and it's many years ago now, but he stuck in my mind as one very smart cookie with an almost weirdly-natural grasp of radio engineering theory and practice.
Over the last couple of decades I've read both his old and new blogs on and off, and while I can't say I always agree with (or even necessarily completely understand!) his posts/explanations/arguments, I usually can't completely disagree with them.

Since I am new on this site I decided to spend some time finding out who is Mr. Owen Duffy,? VK20MD whom you have been frequently referencing regarding SND evaluation of loop antennae.
Is he australian HAM amateur representing National Association for Amateur Radio in Australia and a good practioner in radio field ?
