Are you sure RTTY is LSB? Any time I've - mistakenly - set the rig to LSB and tried to copy RTTY, I've had to invert the signal to read it. On USB I don't have to do that.
I was also under the impression that all data modes are USB, irrespective of band... Certainly my experience so far. 73 Bob 2M0KDZ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
