The key appears to be whether the information is printed immediately or not. In
97.3, RTTY is defined as Narrow-band direct-printing telegraphy. So text is B
if it is printed or D if it is not printed.
It's interesting that emission types B7W, B8W and B9W (ISB) are still allowed,
so you can
I would expect that we will be able to get some help from ARRL HQ on
this since they could publish a list of modes along with their
classifications. That would help a great deal.
Don't know if you saw it or not, but the ARRL updated the article on
their web site today specifically on this
AH! Ok, that works...Thanks---Bob C.

I have begun using the term The Digital Radio Group, when referring
collectively to this email group. This group has almost 2,500 subscribed
members , therefore I think the group represents an active constituency of
data oriented radio operators.

I believe this group on average is much better equiped to represent
our interests than the ARRL is. This action appears very necessary,
now and on an on-going basis.

The direct printing could also refer to the older technologies of
printing to a TD couldn't it? It would be possible to then relay that
information without actually printing it out, such as on a sheet of
paper with a teleprinter or on a monitor screen? Or would that become data?
It is

is digital, as is RTTY. Its the scheme of the on/off or mark/space that
gives us the mode of digital transmissions. Analogue is a smooth (albeit
sometimes very rapid) transition between the bandwidth limits. Almost all
it seems to me is this regulation by emission designators.

For software control with a computer, the only partial solution was to
use a Pactor I program developed for Linux, but from comments from those
who have used it, the results were mediocre at best since it can not
equal the dedicated box. I am not sure if this is still true with the

I sure hope everyone who has a complaint about the new rulings is

Hello to all
We would like to experiment APRS PAX (PAX not PAX2) transmission through a PAX
repeater.
Fred (OH/DK4ZC) proposes to be a PAX repeater this saturday 18/11/2006 from
15h00 to 17h00 UTC. His locator is KP30JK in Finland.
From 15h00 to 16h00 UTC Fred will beam towards Europe and from
Yes you are correct about regulation by emission designators. The
question really is when is the third symbol of the emissions
designator a D? 97.3(c)(2) says that data is Telemetry, telecommand
and computer communications. The third symbol of an emissions
designator identifies the content
Agreed, that is why in general I would not expect this group's opinion to be
expressed. In my communication with the FCC I did not express an opinion,
but asked them to clarify some points.

The FCC uses the phrase quantitized or digital information in the definitions
in part 2 so anything encoded into discrete levels of amplitude, phase or
frequency is digital.
The definitions in part 97 were probably very clear when they were written. It
looks like they took amateur radio terms
Mark,
In reviewing the comments some things stand out that I missed before:
1. In your petition you recommended the wording for the definition for
data to be changed:
emissions A1C, F2C, J2C and J3C having an
occupied bandwidth of 500 Hz or less, and J2D.
In the ARRL comments to your
First to the list, I am sorry about the fonts and
alignment of that post. I am not sure what happened.
Rick,
You notice where the J2D should be emissions A1C, F2C, J2C and J3C having an
occupied bandwidth of 500 Hz or less, and
J2D. NOT emissions A1C, F2C, J2C, J3C, and
emissions A1C, F2C,
Well said , I agree, that is why I did not dare to express anyone's
opinion.

I have been in touch with some staff at ARRL HQ about the 500Hz data matter.
Their official position is that U.S. hams should be conservative about
this, and avoid using 500Hz data transmissions until they have clarified the
matter with the FCC. Unofficially , there are some ARRL advisors
