Well PSK31 is narrower than morse code but the problem with it (according to
our local PSK31 guru) is that because it is narrower, it is hard to find the
PSK31 signals unless you know exactly where to look. I.e. just dialing
around, you easily zoom right past them without ever knowing they are there.
For that reason, I believe they have established calling frequencies in each
band so they can find each other. Plus they use some type of software to
scan and show peaks. I'm not into myself but we have several in the local
club who are.

PSK31 is simple. Almost all the programs have spectrum graphs, or
waterfall displays to show signals within the passband used. Yes, most
PSK is on an established freq, +- . You don't "dial around" for PSK31.
You tune the radio to the set frequency, and the software is used to
"tune". Say 20m, you would tune in 14.070.15 and all the rest is done
in the software. You see a spectrum graph that shows all the signals
in the passband. To receive one, you just click on it. Bingo, it locks
up and starts to receive. The program I use "hamscope" can receive two
at a time in separate windows. Also works rtty, bpsk, etc..Most all
the common PSK freq's are at .070.15 per each ham band. IE:
3.570.15
7.070.15
14.070.15
21.070.15
28.070.15
Maybe be others such as novice PSK, etc .. MK
