    10. in the MMTTY Engine window panel, uncheck the enabled box

    11. to have the 2Tone decoder decode RTTY in parallel with the MMTTY engine,
      1. in the 2Tone panel

        • check the enabled box

        • click the Setup button

      2. in the 2Tone Settings window,

    12. if you are running on Microsoft Vista or Windows 7, it is important that your soundcard driver's sample rate be an integral multiple of the MMTTY engine's clock rate. The MMTTY engine's default clock rate is 11,025 hz; the default sample rate for most sound card drivers is 48,000 hz, which is not an integral multiple of 11,025 hz. To address this,

      1. click the MMTTY Setup button to make the MMTTY engine's Setup window appear on screen and

      2. select the MMTTY Setup window's Misc tab
