Hi Dave,
I have heard of the use of MT-63 for many years on MARS circuits, but
don't think I had heard about the digital SSTV program being used. It
makes tremendous sense since they are often involved in sending
bulletins to their members. With one to many it is possible to have 100%
ARQ with

Rick,
Army MARS is using MT-63 on mixed mode nets with some regularity.
We also use Olivia when conditions warrant the slower speed of
transmission.
Easypal is also being used for picture transmission, as well as text
broadcasts.

Maybe some of you can help me with understanding the current digital
state of the art with NTS. Recently, there have been some NTS
yahoogroups formed for our region and the sections in that region. There
is no digital presence at this time, however, at least one ham I knew in
past years (now SK
What I would like to know is what "negativity and misinformation" was
even mentioned.
From now on lets be fair about making such statements by actually
quoting the alleged negative and misinformed statement so the rest of us
can make an informed decision whether such claims are even appropriat
The *only* ill will I've seen expressed is over the use of automatic stations
that transmit without first verifying that the frequency is in use. This has
nothing whatsoever to do with modes. It is unfortunate that one particular mode
(Pactor 3) is conflated with this style of operation, but as

Steinar,
I think the 'request' may be based round 'access for all' and not the
banishment of the mode ..
In a abstract way, this seems to fit the bill :)

There would be no "mode wars" if people take the time to understand the
benefits and limitations each mode has and make it a personal rule to
test the mode fully in a live setting before applying negative comments.
So much understanding can be gained from experience.
The same goes for sound car
Why is there a need in ham radio for mode wars?
Is it counterproductive to have so much negativity
and misinformation being spouted about various
digital modes and methods by those who profess
to be proponents of digital ham radio?
Why is it necessary for a person who advocates

I am not necessarily opposed to other hams using Pactor modes, but the
one issue that is consistently ignored seems to be the transmission of
fax/image data when using the wide bandwidth modes. If kept at 500 Hz or
less, the changes in the rules a few years back finally allows fax/image

Simon,
The problem is not with Pactor, per se, but with the arrogance of those who
consider retrieval of their precious email more important than the QSO that is
already on the frequency. They just happen to be using Pactor, but since Pactor
is an ARQ mode, and usually linked to a robot, by usi

Two areas where there is a need for digital comms:
1) Satellite / deep space
2) Boat owners far away without internet (let's ditch PACTOR please)
I'm indirectly involved with 1) and am following the WINMOR project which looks
very interesting. Here in central Europe there's not a huge need for e
Rick and Dave,
NBEMS was created and submitted at the eleventh hour as a reply to Rinaldo's
search for an HF protocol, but instead as a VHF system, mainly for emcomm. We
afterwards expanded it to include HF messaging for extended range where VHF
does not work, but is still primarily a digital m
Good points, Dave,
Considering that RTTY, the oldest digital mode (not counting morse code
which goes back to spark), is still one of the most common modes, and
PSK31 is the most common of the newer modes, it appears that there is
only a small interest in any new digital technology. When I ask
