Now I'm really confused. I thought I had it straight in my head, after slogging through all the info in the ARRL posts, etc., that we would NOT be able to have more than one PSK (or CW) QSO going on in a given channel, because we are required to always put the one PSK or CW signal at the same offset within that channel. >>>>>NO!

I remember being disappointed in the idea that we wouldn't be able to use a single channel or two as a virtual CW or PSK "mini-band", thus making much more efficient use of the limited spectrum being made available to us. >>>>>No, only the center frequency is available.

The conclusion I reached was that even if that would be the most efficient use of the spectrum, that it would likely drive the primary users nuts trying to figure out how to shut up a whole crowd of users when they wanted to use the channel, thus the reason for barring us from stuffing the channel with multiple narrow-band signals. Did I somehow misread the whole thing? >>>>>>I see nothing in the info in the federal regiaster poosting about just >>>>>>a single user at once per channel.
