  SPECIAL EDITION

  This Special Edition of the CGC Communicator is to reproduce
a few long-form letters on XM Satellite Radio, and other matters.

  Next week, we will return to our short-form format.  All Letters
to the Editor must consist of nine short lines of text, or less,
to be considered for publication.  The subject title and author's
name are not part of the nine line count.  This letter, for
example, consists of nine short lines.

  While long letters are always welcome for extraordinary events 
(like XM), the short-form format is still what we are all about.

  Thanks, Editor

  HELP NEEDED WITH MICROMAX CART MACHINES

  This is for any radio station engineers who may be able
to help me in my time of need.  KFWB-980 is in dire need of
parts for Micromax reproducers.  If any of you have any parts
for these machines, especially pinch rollers, ceramic capstan
shafts and drive belts, please let me know.  Also, if you have
any of these cart machines and would like to dispose of them,
please let me know.

  Harris, who bought PRE (Pacific Recorders & Engineering),
no longer supports these machines.

  XM COMMENT #6

  The XM sound, while certainly not "CD Quality", is 100% better
than FM Stereo.

  True, some songs on some channels do sound mangled, but is
this due to entry-level people adjusting incorrectly, poor
dynamic processing, concatenation, an inherent flaw in the 
system [or sub-standard source material]?  Not that it matters.  
Overall, the sound is quite acceptable to the end user for casual 
listening.

  In fact, many people report a very satisfying listening
experience and I (and others) have noticed that the coding seems
to make it easier to hear certain sounds, previously unheard,
in old recordings.  Plus, the bass is awesome (which kids like
a lot).

  Dave Rickmers, Sulphur Springs

  XM COMMENT #7

  The fact that Greg O. doesn't like the sound quality is not 
surprising...  Greg has been at the forefront of making the 
commercial AM & FM bands sound GREAT, even though years ago some
clown thought it would be a good idea to shelf the FM band off
at 15 kHz.  Personally, I am grateful just to have my GregLabs 
processor for use on my Internet radio station.

  I have XM, as I travel to Mexico (San Felipe) quite a bit.
While the quality is in fact NOT as great as the ANALOG audio
coming from McIntosh gear & Klipsh horns back at the house, the
background noise that is generated by driving 80 MPH in a 2001
Land Rover makes the [audio from] CDs less than perfect also.

  I understand your disappointment; however, no one put a gun
to my head to pay the $9.99/month.  I think that it is important
that those of us in the emerging technology field(s) back ANY
*new* technology -- I'm not saying we should be proponents of
*bad* inventions, but I think it's really important that we
encourage the opening of the "bleeding-edge-door".

  Mike Somerville, Radio Director of Engineering, KFMB/San Diego

******************************************************************

  XM COMMENT #8

  I think the problems people are writing about concerning
the sound quality have to do with the fact that "one size
fits all" processing and compression schemes don't work.  If
you look at a typical FM station with a spectrum analyzer,
you'll see broad shoulders in the spectrum.  An unprocessed
signal would have a xmas tree-like distribution of sidebands.

  If you have a comprehensive record library, try playing
the CD of the cut you just heard on FM using the same amplifier
and speakers.  The difference will be dramatic.  The CD sound
is more open and the frequency distribution linear.  Processing
and compression alter sound.  If tailored, cut by cut, the bad
effects can be minimized but not eliminated.  Putting all the
music in a library through an untailored P&C path is a recipe
for bad sound.
