      Hi Lasse,
      No you are not a Simpleton and thanks for the help! Just checked the tones
      and they seemed to be matched up. So I will forget the bar over the CW and
      RTTY modes. For some reason I thought the tones were reversed, that what
      you get with no sleep. I assumed wrongly that if you are on CW-R it was
      reverse from the Icom. What was messing me up in the beginning was BobCAT
      after the modes where added so I was really chasing my tail. I had a lot of
      things going on and to sort out.

      So if this is like Harry's I am good to go.

      Thanks Lasse for hanging in there with me!

      I may be a Simpleton...

      I still do not get what's wrong with your set up!
      Icom CW and Perseus CW-R are technically the same! Just different names due
      to the fact CW never have had a standard. So when a designer decides that CW
      for his (or her) radio will use one of two sidebands the opposite sideband
      will be reversed.

      IF they instead had name it CW-LSB and CW-USB, noone would be confused :)

      When Commander sends its CW command (CI-V sub-command $03) it will set both
      your Icom and your Perseus to the same CW-LSB setting Nevermind that Perseus
      shows CW with a bar over it....

      Do you get the demodulated tones to go higher in one RX and opposite in the
      other.. then you do have a mismatch.
      If so, let us know!
