Yes, I agree and in my earlier post I stated; "it's easy to be loud, just
buy another amp and crank it to the max. Now being good, well that takes
skill, knowledge and talent." Also, I've mentioned many times that good
audio has a lot to do with good mike technique.
Bob Heil has a very good presentation and demonstration that can be found at
http://www.youtube.com/watch?v=tX9J6Vre3j8 The mike technique starts about
20 minutes in and runs for about 8 to 10 minutes. It well worth watching
and there's lots to be learned.

Being the owner of a recording studio as well as a ham for over 40 years,
I can verify that cost has very little to do with frequency response and
audio quality of most microphones. I have built condensor mics costing
only a few dollars that perform as well as $500.00 microphones. Like in
the studio, the most valuable piece of equipment is your "ears ".
Everyone thinks the solution to every problem is to throw money at it
instead of maybe using better " mic technique ". I hate hearing stations
where the compressor limiter is set incorrectly and you can hear the audio
pumping.

Well said, Bob.
Last summer, on a Brand X discussion forum, we discussed what is the
best" microphone and what is the best EQ setting. I suggested that,
ecause we only use +/- 2700 Hz audio and RF bandwidth - pretty much any
ecent microphone costing $15 or more SHOULD be linear across that
arrow spectrum, and I made recordings of several microphones bearing
idely different price tags to prove it. No one has correctly
dentified the $15 Samson RS10 from the $150 Heil PR-20 or even from
he $99 Sennheiser e835, and several others by RadioShack, Shure, and
he real kicker in the bunch... a $1 computer mic I purchased on eBay.
I dared to suggest audiophiles use EQ to "fix" or compensate for uneven
oom acoustics ... but oddly enough audiophiles often employ pre-amps
nd power amps lacking any bass or treble or EQ controls at all -
nstead they seek uncolored input, and uncolored output, using EQ
paringly or not at all to compensate for uneven room acoustics. So,
n that logic, maybe we should use FLAT EQ on the transmit audio, on
he theory of what goes in uncolored and natural, might come out
ncolored and more natural than if we had messed with it. After all,
ost decent microphones are linear across the 200- 2700 Hz +/- range -
f we want to sound natural, why color it with phoney EQ settings ?
I am sure there is some fallacy lurking in the weeds, but this seems
ogical to me. Garbage in... garbage out... Natural, simple audio
n... ok you get the picture.
So I keep it simple, I use reasonably good, but not overly expensive
icrophones, and avoid excessive EQ coloration (occasionally I add a
light boost to the mid range frequencies to be more punchy in a
rowd... but not otherwise.)
Am I missing something?

I hate to say it folks but we are using a communication audio range
which is typically comprising a frequency response between 200 Hz to
2500 Hz out of the entire audio spectrum That range is defined by the
filter, be it hardware or DSP, that is part of the SSB generator.
Trying to cram wide band audio through a filter of this bandwidth is
like trying to push a bumble bee through a drinking straw. Nothing nice
is going to come out the other end. Just like I tell the kid in the
band, it's easy to be loud, just buy another amp and crank it to the
max. Now being good, well that takes skill, knowledge and talent.
Now lets try to get the best quality out of the 200 Hz to 2500 Hz
spectrum of audio that's available. It is a lot more of a challenge
than buying and using some external processing and EQ and broadcast type
mikes.
