      thanks for your reply. When i got you right the audio tones in the test mode
      are the same as during real operation? So in my case
      1200 / 2200 Hz for 1200 baud and 2100 / 2300 Hz for 300 baud? Sorry, but due
      to a current lack of any measurement equipment in my shack i can't find it
      out on my own and i have to ask this (the single tones were measured with a
      simple DMM).

      If that is the case i could live with it, as you mentioned i just would have
      to tune to another center freq on HF.

      Unfortunately PSK-31 (or even PSK-250 for) doesn't work yet wih the T2m ....

      Best regards
