I am unaware of anyone suggesting Winlink being
"discarded".  That is a red herring.

The points I made, and they were intentionally
precise, were:

1.  Were any other weak-signal digital modes tested?
Winlink is one of many, and one of the most complex.
Why test only the most expensive and the most complex
rather than several different digital modes?

2.  In proper emergency communications planning one
*always* seeks the most commonly available, least
complex, and most effective mode(s) for communication.
There is no evidence that such was done re. digital
modes in this case.

3.  Winlink was not listed as to be "discarded", only
as not the wise choice as a top-tier tool.  Nothing
presented in your reaction/reply has in the slightest
way factually argued against that assertion.

There are standards and science which are supposed
to guide professional and wise decision making for
emergency communications.

The assertion that Winlink is (or was) the only and
best mode simply fails to meet the standard.  That
Winlink was the *only* weak-signal digital mode tested
makes an entirely different statement having nothing
to do superiority and something else to do with
skewing the playing field.

How about inviting operators of several different
digital modes to the test.  Then using real-world
probabilities postulate equipment failure.  It is
impossible to not find a higher probability that
necessary pairs of rare Winlink stations at both
critical ends will either not be in place or suffer
some sort of failure then one of the more common
(due primarily to cost) and more reliable (due
primarily to simplicity) digital modes will really
be there when things really get ugly.

Let me illustrate.

If one does a test that says that one must complete
a relay of a package across difficult terrain and
the vehicles chosen are two each Chevy S10's (SSB Voice),
Honda Accords (CW), SUVs (complete VHF/UHF FM Repeater
Link system), and Hummer H2s.

Those vehicles would need to be in precise positions
(the equivalent of EOC's) prior to the suddenly declared
relay.  They would have to be fully fueled, manned by
competent drivers, and absent mechanical problems.

One would face a series of serious challenges.

Winlink, like the Hummer H2, is rare and the probability
that sufficient hardware/software combinations at both
ends (and "both ends" is an unpredictable because EOC's
may be breached by an earthquake or terrorist attack)
when needed with antennas and power and everything
required is highly improbable in a properly designed
scenario.

Furthermore, due to the complexity of Winlink the
probability of failure in one or both of the rare
pairs required is also high.

Just as they postulated that your vhf/uhf repeater
would fail so they would equally have to postulate
the failure of one specific Winlink pair being in
perfect position operating perfectly undisturbed by
the same or some other variable.

If one postulates that the very common (Read: redundancy)
S10s, Accords, and SUV's all failed and that two rare Hummers
were in the right place at the right time with all variables
intact and suffered no failures (in spite of the complexity
and in spite of no redundancy due to cost) one has postulated
an absurdity.

Consider the many other far more common digital modes
and one sees clearly the fallacy of the Winlink/Hummer
postulate.  In emergency/mission-critical planning
redundancy is king.

These are simple and indisputable facts that no
emergency management professional may ignore unless
he wants to end up like the former FEMA Director.

IMHO, YMMV ... 73, doc kd4e
