Barry, I agree. I have a good background in engineering level testing, and one of the pre-requisites is to establish a level playing field for such comparisons. Just plugging in two radios and listening to them with no other information about the similarity of the settings would be thrown out of any decent "test" environment. The evaluation is entirely subjective unless it is supported by data substantiating the differences and the equalities.
Take a look at the ARRL Lab test setup requirements as an example - they would never compare a 500 Hz bandpass to a 2.7 khz bandpass and expect the same results. I do not see any information about the setup parameters in that video. Yes, there were some comments by YO3GIC "after the fact" that "said" they were the "same", but the "if I remember correctly" does not speak to any recorded data. At one point, I saw the K3 HI CUT knob turned, but did not see any comparable adjustment on the FT, at least there was no information about what was being done and for what reason. In all cases, my ears told me that the K3 provided more intelligibility, and the only "advantage" of the FT was an extended bass response. Maybe my ears are different than others, but I would judge the audio from the K3 to be more clear than the FT in this video. I wonder where the Lo Cut was set on the K3 for this video? If bass response was to be the "evaluating parameter", did the K3 have the new DSP board installed, or was this a K3 prior to the DSP upgrade? Too many questions with no answers for my blood. 73, Don W3FPR On 11/21/2010 7:21 PM, Barry N1EU wrote: > For two radios that both feature an audio passband that is SOOOO adjustable > in so many ways and likewise so affected by button/menu switches, it's > almost criminal to put up a soundclip like that and call it a comparison. > The obvious (duh) protocol should be to first adjust the rigs and equalize > the passbands as closely as possible while observing the audio spectra, use > similar gain/agc settings, and then finally let 'er rip. > > Arggggh, Barry N1EU > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
