I don't suppose you measured that either, did you? Do you know why that is important? Because you don't state the HAAT of the antenna for either the transmitter or the receiver, nor do you state whether the 13/24 miles was flat. If you just wanted to get a relative signal strength reading without the confound of HAAT, why did you stroll 13 miles instead of only half a mile or so? All you needed to do was clear the near-field, which most engineers consider to be six wavelengths for HF (or 66 meters, a far cry from 13 miles where a lot can happen inbetween). There are WAY too many issues with your test, and any or all of them could have been a factor in your inconsistent readings. Looking back an those threads, it appears that you already knew that, too. I agree 100% Frank, you raise many many valid points as to why this test is really bougus. Which points? You don't have a clue what Frank even posted. Even if he doesn't, he should be able to recognize Tnom's subjectification of a supposedly objective experiment, his inattention to detail, the lack of critical information, and his failure (unwillingness?) to disclose his previous test and it's contradictory results. That, in my book, is sufficient to conclude that Tnom's tests are bogus. In fact, the results of the second test are almost -too- good, skewed out of proportion with reality -- almost like he was reading the S-meter backwards -- and extrapolation of those results suggest that the rubber ducky is the most efficient antenna design, second only to the theoretical dummy load! It doesn't take an engineer to see that much. Maybe he should be able to recognize a lot of things, I doubt that he even fully read what you posted. |
