This is a question related specifically to voice modes (SSB) and in
particular comes down to the sound of Orion. It is not about how much
bandwidth you like as no doubt we all find that varies with the specific
conditions at any given time. Rather it relates more to the shape of the
passband you might find best. Personally I find that the fairly well worn
and acknowledged 300Hz to 3kHz is about the ideal under most circumstances.
I can manage with less and appreciate it when the conditions are rough,
preferring something a little more focussed toward the higher end and going
as far as 500Hz to 2.6kHz and maybe a little further in some extreme cases.
But in all cases I like it to be reasonably flat in the passband with a
regular and defined roll of outside of those limits.
Ever since I got my Orion I have been running the Rx Eq at fairly high
negative values -16dB to -20dB but have always felt that this is not doing
what I want. Recently I have started to do things differently, and with
startling results, to my ears at least. Appreciating that we all have
different hearing characteristics I would be interested to hear what sort of
audio spectrum shape you like to listen to for radio work.
