      Hi  Gang,
      Please, if  anybody  knows  ALL  ABOUT  SG-237.
      I  purchased  this  SmartTuner  in  July  because my
      LDG  AT-200Pro Autotuner  performs  only  7-21
      mHz. Another  bands - with  "HISWR", 1.8 and 50
      don't  included.
      I  fired  a 160'  loop  on  a  big  tree, put  the  tuner
      on  a twig  above  my  trayler  and  started  to  tune
      using  10 w  of  FT-897. All  bands  worked  with
      SWR  1.1 to 1.5, but  1.8 and 50. I  lengthened the
      wire (14 AWG  with  thick  insulation)  to  269'  on
      2  big  trees. 1.8 and 50  worked  only  sometimes.
      SWR  of  another  bands  also  was  unstable.
      I  made  adjustments  of  the  length  under  the
      email  directions  of  SGC  technical   support.
      Once  all  bands  were  with  SWRs  1.1  to  1.2,
      including  1.8 and 50! I  was  so  happy! But  on
      the  next  day  all  SWRs  were  bad. I informed SGC.
      They  were  surprised  saying  that  the  tuner  should
      work  at  ANY  length. Finally  they  adviced  me
      to  send  them  the  tuner  for  repair. I  did, informed
      them the trucking # and  got  their conclusion.Read it.
      Now  I'm  using  the LDG Autotuner  with  1:1 balun
      on  twig. SWRs  are  1.5  on  7 to 21, on  others  too
      high. I  live  in  RV  camping   resort  with  Rule 31:
      "No ham radio usage". I'm  illegal  and  my  signal
      shouldn't  produce  QRM. But  I  love  contests.
      I  think, SG-237  either  was  damaged  before  my
      purchase  or  it's  components  corresponds  to
      MARINE  "consumption", not amateur  radio in full.
      TKS  for  any  idea,
      Leo, N3GD  in  Davenport, FL

      Dear Leo,

          Once we receive your unit and complete a diagnostic evaluation we will then
      determine how we will proceed.  Your antenna is very strange.  WIth all the tree
      moss, etc.  we don't see how it can hold a tune.  It should be hung freely with
      no contact with any part of the tree - that means removing any surrounding
      branches, twigs, etc that can 'sway' into contact with the antenna.  Then you
      could to a basic test on all bands and verify you have a solid match.

      Best regards,
      SGC Technical Support
