doug i know a guy that put a mike element in a piece of pvc pipe with a lttle cotton in it.  it sounded fantastic beat any 300.00 mike i ever heard.

crazy huh?

all things are possible in Christ Jesus our savior

 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
 arrow spectrum, and I made recordings of several microphones
 idely different price tags to prove it.  No one has
 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
 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
 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
 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
  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
