Here is a response I got from Dan Henderson, N1ND, ARRL Regulatory Information
Manager about the legality of ROS here in the states. My question was very
simple. Is ROS a legal mode under FCC rules and if not, what would it take to
make it so. Here is what Dan had to say.
From:
The only problem is that Mr Henderson is mistaken in one regard. Per Part 97,
spread spectrum is not authorized on 6m or 2m. The rules specifically state
(section 97.305(b)) no SS modulation emission may be transmitted on any
frequency where SS is not specifically authorized.. A review of
Keith,
While ROS is not legal on HF it still is not legal on 6 or 2 meters here in the
states, it is legal on 1.25cm and above. Please see Part 97.305 it clearly
states where spread spectrum is authorized.
This issue has been hashed out on numerous threads and I wouldn't want to put
my
What Andy and Skip said, plus a top corner feed causes a pattern distortion in
the broadside that narrows the beam width a bit. A bottom element feed through
a parallel network has no pattern distortion but requires ground radials.
However you can put down a very minimal ground radial system
Just what we need is spark-gap radios on 6 and 2 meters. We just got through
fighting this a few years back.
Since 223 is little used and it's legal whats the problem with going up there ?
Chuck is right why is it that SS users feel they need to go on widely used
bands ? Even if legal the
Tom, with voltage feed, you only need an electrostatic ground. I used
about 10' x 10' of chicken wire for a ground sheet under mine in Hawaii.

I know CMSK is mainly for 160/80 metes (which I currently can't do), but what
freq's are being used currently on the other bands/

Dave, KB3MOW, has suggested 14079 + 1000 Hz, USB, to me for a test on 20 m. I
will be available there around 22.00 UTC or a little bit later.

I alternated calls to you and calls to CQ and never heard another
signal. Not sure how propagation is, though.

Steve,
There have been some terrific responses with some great advice.
I'll focus only on the interface between the radio and the PC's soundcard.
Even for casual usage, I'd recommend that you not use the built-in soundcard
that came with your computer, and that you probably use for PC things
