Let me give one incident where high through put would be most desirable... When hurricanes hit the Texas Gulf Coast, all but radio communications can be lost between Brownsville, Texas to Houston, Texas. The weather stations there may have their eather radars operational but unable to send the "picture" or data to other weather stations. A highspeed, error free, robust, realtime, HF data mode is needed. The radar information may be 7.50 K bytes or larger. This data would need to be repeated every 5-10 minutes during critial stages of a hurricane.

I think this limit only applies to protocols that do not make use of FEC, redundancy and adaptive training. Adaptive training may be the most important element. 73, Mark N5RFX Need a Digital mode QSO?
