And when the bands are crowded the receivers must be made narrow. And then, as I pointed out, it is impossible to have a wideband system because the receiver is a part of that system. And remember th
Well Keith, I agree with you -- that's why I said I didn't want to do this -again- here before. However, it did prompt me to setup an experiment I've been meaning to do again, but more in depth this
Let's keep in mind that having audio frequency components above 3 kHz doesn't necessarily require us to have a transmitted bandwidth in excess of 3 KHz. That's why we have passband tuning, VBT, and t
Hi David, A data point. The Kahn envelope restoration scheme is best employed for low duty cycle signals, like SSB, and employing tubes that were happy in plate modulated AM service. Their power out
All I can say is that when there is significant noise & QRM, that extra couple hundred Hz of articulation seems to make a difference. Has anyone else experimented with that? Joe, N3JI Well, In my yea

Going from 300Hz to 200Hz does nothing for a female voice, but it does add something to most adult male voices. R L MEASURES, AG6K. 805-386-3734 r@somis.org __________________________________________
I do all the time, and when there is significant noise and QRM **LESS** bandwidth improves copy provided that bandwidth is properly centered. If you listen to widefi AM guys, those with the deepest
I'm only going to say that to dismiss something solely because "it's always been that way" is a terribly closed minded way to look at something. I'm fully aware of why ~200-3.4k was chosen (as I ment
