This offset shouldn't really have a big affect - I would be wondering about squelch levels or even the soundcard. What is the soundcard? Internal or external? RTTY is nowhere near as good as PSK when it comes to weak signals. I've encountered someone with a soundcard running in surround mode :-( Simon Brown, HB9DRV www.ham-radio-deluxe.com
