This is almost perfect with this "basic" antenna raised against a window.
The question I ask myself now is whether the 3500STB tuner would not be too sensitive and that the phenomenon that I see would be due to a saturation of the input circuit.
I should use attenuators but I'm on vacation in Canada, where my daughter lives and I do not have them.
Yet this test could be interesting because I lost the weaker U.S. channels with this dipole (chanel 22, WCAX-HD).
My daughter has to be be satisfied with this compromise until I be back for my next vacation.
I will bring attenuators from france for this occasion.
Who knows if "saturation of the input circuit" is the problem. I've already posted that the strongest station for me OCCASIONALLY will show "NO SIGNAL" on the iView with a "Signal Strength" of 100. What's the problem? Is it the fact that this station broadcasts something like 2MW+ from about 12 miles away? Is it because of that coupled with the station is about 65 degrees off-beam, and maybe there is some multi-path sneaking in there too?
My iView also has another reception quirk. For at least one station, it will tune into the station for a few seconds, stop and go to black for a split-second, show the station picture again for another couple seconds, then stop/black again, the finally tune into the station for good with no more interruptions. Is this because this is a station that uses a (more) local translator antenna and the iView is hunting back and forth between the two frequencies before settling on the "best" one? Again, I don't know, don't have the same problem for my other TVs, but I generally have a problem that the TVs show double the number of channels for those stations that use translators, one set of channels for each frequency, and some of these unneeded (by me) translators block me from getting distant stations broadcasting on the translator frequency and I'd really prefer to receive those distant stations (one of many reasons I don't get as many stations with digital that I used to get with analog).
It's just difficult to figure out what is going on with TV reception in general...I just switched from my home-made antenna (which uses coat-hanger wire for the hi-VHF section) to the RCA ANT751, and with the antenna in the exact same position I picked up a station with four channels that had been missing for months, but lost another station with three channels. Moved the ANT751 a few inches over, lost the four channel station and got back the three channel station. Overall, I'm showing weaker signal strengths for the ANT751 than for the coat-hanger wire antenna, so I may go back to coat-hanger wire with a simple UHF loop that I used for years that had the best overall digital reception of any antenna setup, and see how that's working these days.
Also, I would really like to start using the iView as a quick and dirty DVR, and am just about to go ahead and buy a new USB drive for this purpose. Would I be wasting my time and money if I used this old 1TB USB drive I have now (replaced with a new 2TB drive) for recording using the iView? Would the iView burn up, would I ever get a simple same day time-shift recording? I fooled around with a flash drive and as predicted that resulted in HDTV picture skipping every few seconds and I had a hell of time trying figure out how to program a recording, and I'm not confident I'd ever be able to do it given the crazy bad nature of the iView firmware and remote (I'd still like to get my hands on the source code for the firmware to fix it)...
