Not sure how this relates to your post, but from watching many hours of RTTY with only 170 hz between the tones, I have seen one tone fade and come back in several seconds, then the other tone will do the same thing. This was observed watching an oscilliscope hooked to the mark and space filters of an ST-6 demodulator. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
