Since Bill Wuttke is getting errors I did a bit of checking. I got my tones from icecast on a second computer and looked at them on a 'scope. They are not the same level. Surprisingly the space tone (2425) is slightly higher than the mark tone (1575). On steady steady mark between news articles I set the 'scope for exactly 4 divisions. On data the space tone was hitting 6 to 8 divisions. It is not much but could possibly cause distortion if not limited first.

There also seems to be a few cycles of indecision between tones.

I am happy to see two people on that stream as I type this.
