RE: RF coax

Good article Jon, and I even agree which is why I've never tried them. But sometimes things audio work out differently than I think they will... However I have no problem continuing to give them a pass.

While not a TV fancier myself, I used to work in the same lab with both video and TV RF guys and I doubt if they would agree with you that "the levels of distortion that become visible are orders of magnitude higher than the levels of distortion that can be heard". The phrase most commonly heard, usually expressed in agony was 'group delay'. And even the RF guys fought it because even though the BW was far less than the baseband video they had to design incredibly tricky, high-Q filters to keep out of the adjacent channels. I was an ignorant, unbiased, uncaring guy working on avionics and so was felt to be a good 'man in the street' test case. The thing that really struck me was just how good clean NTSC video looked compared to the picture on my home TV and while I could see the problems they didn't seem very important. Not too surprisingly the video group leader was an audiophile...
