I wonder what kind of investment is required.
It has as many points as possible in common with sound card modes and
only requires MultiPSK as terminal program
Wouldn't the variability be due to not knowing the conditions we operate
when on the air vs. the controlled and known conditions during the test?
There are times that a given mode just can not work in a real world
environment, even though you might be able to hear the signal just find.
It just

As has been mentioned before, the best way to get the various flavours of
ALE400 added to the various digital programs we use is to make source code
available, failing that a good spec.

Simon;
That said, what would it take to convince you and Patrick to work on a
project,(besides time), hm?

Hi,
I'm working on at least a million lines of code in various Ham projects -
the easiest way for me to add a new mode is if I have the source. Patrick
writes in Pascal, myself in C++.
To be honest I see Olivia and MT63 as the most reliable modes out there.
Simon Brown, HB9DRV
at the first step. There is just to choose the mode to
work.
Now each one must choose according to his/her needs.

When the C++ code is available I'll take a look for sure :)
I understand not shipping your code if it's mixed up elsewhere.

While I have seen how well ALE 400 works, I am not convinced that it
is worth the effort to invest in activity due to the lack of other
hams using the mode. While ALE400 make sense to me, I can't see hams,
en masse , switching to it. I still think that a better option would

If I am not asking for a comparison between apples and oranges (I am not
entirely convinced right now... 8-) ), maybe Tony could

John,
ALE400 is not the best mode for this, not because it is a poor mode, but
because the user interface is very difficult to use and has turned
off many
potential operators.
Is it difficult to use? I have honestly not found this to be true. I
agree it is very different than what
With any new mode or system, I tend to factor it with a view toward
public service. But that does not mean it should not be used for what
the majority of hams use day to day. Anything you are familiar with and
use regularly will have much more value than something that is only used
you are right I do like multipsk and particularly ALE400. Works well in to
the noise .
I don't find it hard to use, but I have spent some time using the software
and am not intimidated by the user interface. When I try to encourage others
to try it out , their first reaction is that the
I'll agree with John, while many here will find ALE400 easy to
tackle, many average hams will be intimidated by an unfamiliar
process. That is why Skip Teller's concepts behind NBEMS are good,
using mode that many hams use everyday.
