Although Morse code is not the digital mode this group usually
focuses on, I wonder if any of the members are interested in CW
operations and the occasional sked ? By some miracle, a few years
ago, I managed to pass the 13 WPM code test in the USA. I must have

There are different standards (e. g. STANAG 4539) achieving 9600
bit/sec within 3 kHz of BW at an SNR of only 21 dB. That is today.
The ITU is adopting further standards on HF which will exceed this
with similar bandwidths. I don't believe anyone expects to experiment
with or achieve a
I believe that the ARRL is suggesting that symbol rate is not the
best way to define a protocol. The symbol rate of most any modern
protocol is going to be much less than it is currently defined. For
example, Pactor 1 has a symbol rate of 200 baud and a speed of max
speed of 200 bps, while
However, unless Part 97.1 is changed as to the purpose
of Amateur radio, enhancement of the radio art also includes HF. The
issue is that there is little incentive to further develop digital
protocols for high speed binary transfer since under Part 97.221,
there is little space to use

It may be technically feasible to do everything WinLink, the ARRL and
others may want to do by allowing more spectrum to be allocated to
these services, but by doing so is the resulting environment still

This question, to me, is what it all boils down to.

It is not just emergency traffic, but HW traffic, important

include systems such as Winlink 2000, but for the most part it will not,

Rick you make some good points in your post, and I think the ARRL

It's time to change the subject to reflect
what you are now talking about.
It has moved from the ARRL proposal to an anti

Please remember that before email ham's
had been doing the same thing for years.

I think I can answer some of your questions.
The ARRL definitely has taken the issue of having some kind of workable
network for emergency to heart. At least the past president did. After
doing a test to demonstrate how effective amateur radio networking is,
we were unable to deliver messages

Please get your facts right.
I and others have been using digital voice on the HF bands for
the last 3 or 4 years in less the 2.5Kc.
Even from to mobile.

I think most members are not going to be all that upset with what is in

used for other narrow band modes such as PSK31 and maybe some others
that have not been invented yet to fit in that size of bandwidth), a

John, what are you using to do this. Can all of us do it, with simple
equipment/software? Thats where we need to go. I dont want to spend (and
cant) hundreds or thousands of dollars to speak with a few well heeled

We should not rule out certain applications of amateur radio just
because the majority of hams currently doesn't find them interesting
or useful; that's the road to technical stagnation.
We need only insist that all amateur applications be responsible in
their stewardship of our shared
