Gentlemen,
Excellent!!! Ideas!!! I have hearing problems, although I can make it in
the outside world, telling the difference between modes can be a major pain.
RSID has and will continue to broaden the scope of my digital operating. On the
other hand, Gavin I see your point, and will shut

Do you really think the FCC will put that much effort into this? They really
want amateur radio to be self regulating. I think that people who bother the
comish with such trivia degrades the hobby. When the administration of our
activities become too burdensome, the FCC will be less inclined

I'm sure there are some who may be unaware of the the NCDXF beacon network (
www.ncdxf.org ) but there's no excuse for the deliberate QRM I've witnessed.
I'm very surprised...

Self-regulating means that we police ourselves and obey the rules on the
honor system. It also might mean the Official Observers assist in
regulations. Regulating means following rules, not interpreting them
for our own benefit, but as accurately as possible.
If you were the FCC and had
Hi Dave,
I don't think using 14.101 USB is the main reason for QRM on the 20m NCDXF
frequency. But some guys were definitely using ROS on 14.098 which was very
silly.
I agree - I think the ROS waveform starts around 400Hz so I would expect the
lowest ROS tone to be about 1400Hz higher than

The problem is that the FCC regulations are overly complex and people need a
specialized engineering background to interpret some of them. 99% of the
licensees probably can't interpret every word in the regulations so they ask
for help in this forum when something is not clear.

Well if PSK125 signals are clicky then that's just as bad as if
it's FSK. However I was able to copy one or two of the

Dave,
There's been a lot of ROS activity close enough to 14100 to cause interference
to the NCDXF beacons, not to mention the Packet network on 105, the ALE network
on 109 and the Olivia activity near the same frequencies. I understand that
some are anxious to work a new mode, but it shouldn't
