[RTTY] RM-11708, the "other side"

Missouri has nothing on Southeastern Ohio and West Virginia as far
as hills and holes.  Even in those areas, properly located VHF/UHF
nodes are more than sufficient to link an emergency area to the
nearest backbone terminal.  In addition, VHF/UHF is far more stable,
less prone to interference and less prone to unstable propagation
modes or atmospherics that cause wide bandwidth modes to slow down
or fail at HF.

Again, there is no justification for Winlink 2000 at HF - or
demonstrated use/value in the last 25 years - as an emergency
communications system in any wide scale emergency.  As a one-off
"safety of life" system with short messages, it's a different story
but those messages are handled adequately (and more reliably) with
the narrow band protocols PACTOR and PACTOR II which have better
SNR/power profiles.
