I think my point of the previous discussion was missed by some. I was just
trying to say that traditionally, AM bandwidth is expressed as the total RF
bandwidth and not just the audio passband.

Subject: [TenTec] Orion Sub-Receiver
> Carl(N4PY) the Orion is my first TenTec radio so I don't know the history
of "specific nomenclature." However, I spent a lot of time with the R-390. I
think you forgot to say that the R-390 had a 4KC(Old terminology :) , an 8KC
and a 16KC filter. Maybe that is what you meant by needing other "choices,"
although with the V1 12KHZ filter the broadcast AM sounded great. I'm not
sure what bandwidth you need for some of these new broadcast modes?

> Grant, "nullified" is a big word. I would just say that there is a better
way to do the demod and the Orion V2 really ought to support it, like the
Orion V1 does. Doesn't seem like a big issue, but it really is part of the
"package." V1 was never fully stable, as admitted by TenTec. But the Orion
had a particular set of "functionality and performance." As part of "fixing
the stability issue" with V2, I certainly expect the full functionality and
performance of the V1 Orion. I am also always concious of the fact that even
if I don't use/need a feature very much, it does contribute to the value of
the radio - particularly if the next owner finds that feature important.

TenTec will actually be able to provide new functionality and maybe even
better performance is some areas - like the AM Synchronous detector.
