Subject:      tuning audio under VCII+

A brief technical note ---

About a week ago a discussion came up in homesat again about how
to tune audio subcarriers on a transponder which is scrambled.
Sometimes this is a problem because the receiver mutes any
subcarrier audio in preference to that coming out of the VCII
- but if you aren't subscribed you either get nothing or a
"barker" channel.

Back in the spring Ron Thompson collected some notes on how
to handle this with various receivers. Ron kindly gave me
permission to post the latest revision of the list.

The following generally require the satellite and transponder to
be already tuned in.  This is a work in progress.  Some steps may
be left out.  These are mainly hints. They are not always perfect
step-by-step directions.

HOUSTON TRACKER
     Use the sub audio menu.

HOUSTON TRACKER 8
     Punch in "74", and tune in service.

HOUSTON TRACKER 10
     Some people use the "Favorite Audio Channel" Feature to
     save KLON in memory.


HOUSTON TRACKER 10 PLUS
     Tune to G5, transponder 2
     Go to audio tuning mode
     Program the left and right subcarrier frequencies with
     discrete narrow
     Press store.

     To Listen:
     Go to G5, transponder 2
     Go to audio tuning mode
     Press "SA" or "74"
     Press "cancel"

UNIDEN
     Some units have a "sub audio" button located on the front
panel or under a hinged panel.
     Uniden's phone number (817) 585-3556

ZENITH 7000 AND 8000
     These receivers indicate "No other satellite radio" when no
other radio is programmed on a particular transponder.
Select "Audio Functions" from the main menu.  Tune in KLON by
adjusting the frequency (or two frequencies for stereo.)  Back out
of the menu, and save the selection as a new audio service.

TOSHIBA
     Call the help line at (800) 631-3811.  Select "4" on their
auto-attendant menu.  Ask for satellite customer service.  They
will explain the "audio-tuning" function.
