XSL Competing with RTTY
Quite a few times when I listen to the various XSL "Slot Machine" frequencies I hear some kind of competing digital signal, some of which seem to be right on top of it. Mostly RTTY, sometimes something else.
Currently, at 1057z, at about 4232 kHz I've got 850 Hz RTTY just slamming in over the top of XSL.
It seems to me that this is happening more and more frequently. Am I correct in that?
