With all due respect to the digital versions of all the modes, RTTY just
hasn't been the same since the loss of the familiar sounds & smells of a
Model 15 TTY unit!

I can offer my thoughts on RTTY.
First of all, I use both PSK31 and RTTY. I also do slow scan TV. I use
my sound card and software for all of these. So to me, it's not a hardware
or software issue that determines which one I prefer.
PSK31 is certainly more efficient. In point of fact, it is only slightly
less efficient than morse code itself. As you all know very well, you can
hold five or six qso's simultaneously within one filter bandwidth of say 2.4
not have them interfere with each other. You can do even better with an
external DSP filter.
But I have to say that RTTY is my favorite digital mode. It does use more
bandwidth, and so of course is inferior to PSK in that area. As a result
you often need to run an amp to get through. But, it is simple to use, and
today's advanced software easily handles the syncing and other issues.
Maybe I just plain like it better ! I know it's silly of me... I shouldn't
try to have FUN in the hobby ! <grin>
