Hi Robert,
first, you must be a good RTTY-contester because we had a QSO in the
Roundup. :-))
Plus/minus 2 kHz is too much for the free space for the NCDXF beacon
system. I think plus/minus 500 Hz will do it.
I am running FSK. And when my radio shows 14100 kHz then my two tones
will be at 14100kHz and 14099.830 kHz.
Soundcard users who are running AFSK can configure their software to
show the real mark frequency. So I think there should be no problem with
transmitting in a forbidden area.

hi all.
Those who use souncards or use FSK keying and set the rig to 14.100,
where
does the signal go.
FSK shift is 2125/2295 for mark/space or 1275/1445 mark/space. When
using
soundcards this can be almost anywhere, I use 1100/1300 because it goes
into
the filters passband on my rig.
The 2 KHZ safetyzone is the minium to set for us not to interfere with
the
beacon. It should be 2500 HZ. There are too many hams out there who
don't
know about this mark/space stuff.
But on the other hand I wonder those who send/receve on the beacon
frequency, don't they have interference from the beacon??
regards & 73 tf3tty robert..
p.s. I wonder how I am doing as a rtty contester!
am I good or bad?
c u all
