When we had severe aurora and you could turn all gains wide open and hear nothing, CW was always the first to be heard from Fairbanks and then SSB. That pattern never failed.
-------------------------------- The narrow-band nature of CW makes it audible long before a relatively wide-band mode like SSB. That's simple physics. Narrower bandwidths mean less noise power coming through, Less noise means it takes less signal to be heard, provided the signal fits in that narrow bandwidth. Here in Oregon it's rare Eu QSO that doesn't involve listening through auroral flutter. Sometimes its TOUGH! But if the other guy'll QRS, it's usually easy copy. That's one thing CW has that phone doesn't: easily adjustable bandwidth and data rates. Saying words v-e-r-y s-l-o-w-l-y on SSB doesn't help much. I submit that the reason virtually ALL emergency nets are phone is that CW requires a skill few Hams have today: even routine CW ops. Handling a QSO, even a rag chew, is a far, far cry from participating in a controlled CW net. That's a skill that takes time, more time, and even more time and a lot of patience and dedication to master. Just ask Kevin Rock who runs the Elecraft CW net! Getting enough Hams current with the skills to do that efficiently has always been a huge problem, even when every Ham had to be proficient at CW to get a license. That's the real reason for all those routine traffic nets we used to have across the bands every night. Even back then, how many of those experienced ops would be in the middle of the disaster, ready to handle traffic? Not many, not often. It's the same reason CW was dropped from the Maritime service. It isn't that the new satellite-based GMDSS system is cheaper to install, it's not. But it's cheaper to operate: no CW operator required! No highly skilled people need be present at the critical moment, like Phillips and Bride sending CQD CQD CQD DE MGY MGY MGY from the Titanic that April night. Nowadays all anyone has to do is hit a big red button on the bridge or pick up a telephone handset. In the Ham world, using phone means that more operators are available everywhere, so there are likely more operators available any time and in any place they are needed.
