  Hi All.

  I am not yet on 10Ghz, but I am far from ruling that out.
  It seems the decision to go CP has already been made and
  agreed to. The only thing left to do now is make a system with
  the best possible circularity. What we do on 2M is to go
  with an already existing convention and make the best of it.
  In that case, a Linrad radio seems to be the best answer.
  A Linrad radio might be a good solution on 10 Ghz in times
  that circularity of the path is not optimal. My point is that
  everyone should follow the prevailing convention and make
  the best of it. There are already enough bands and modes 
  without adding a division of polarity too. I would love to
  see CP as the polarity convention on all bands. It would
  certainly take the question of polarity out of the picture.
  I realize that on 2M, CP will never prevail because it nearly
  prevents working tropo stations on EME. This will not be the
  case on microwave bands. CP is clearly the convention on
  1296 Mhz and it seems to work out very nicely. On the other
  hand linear polarity is used at 432 Mhz and polarity issues 
  are one of the biggest challenges for working that band.
  That should be a clue.
