: If you have to ask, then you are probably using too much. If you are : listening, you probably aren't using enough. If all you think about is : comparing AM to SSB, then you are just looking for a silly argument.
Trust me, Bill, this is not someone "trolling" for a fight in a group. I'm serious when I ask, though - what's the purpose of trying to run audio, starting at 50Hz, on a noisy HF band like 160, 75 or 40m? honestly, from across the nation, those transmitters who have that much low-end response are the same people who want that low-end response enhanced, and in periods of QRM/QRN and selective fade, it's more of a determent to be able to copy, than an enjoyable, enhanced audio performance. I'm absolutely sure that the later is the goal intended, but for talking cross-country on noisy bands, SORRY!, it's just not gonna happen. Now, it's possible to have GREAT audio and still filter and tailor the audio so that it's not out of the passband, such as that of Don Chester, K4KYV. I'm hoping that Don can come in here, and remind me how it is/was he was peaking the audio at around 3kc, and then rolling the whole thing off at 3.5kc (or slightly higher). And, what's the bottom end?
