In the US, the RTTY/data segment of 20m stops at 14.150.
OK, I understand. That still doesn't make it impossible to use somewhere above
14.109 though, does it?
Well I guess now it's immaterial to you guys anyway. What I don't understand is
why anyone still wants to use the mode. The developer has made threats to other
amateurs, he has posted false
. But the situation where existing users of the bands suddenly
have their activities disrupted when people start going mad with some flavour
of the month new mode is unacceptable, and the controls the FCC exercise over
amateurs in the USA do at least go some way to prevent this.
