They like being able to watch all 20 conversations in the bandwidth at the
same time, and see new signals pop up without having to be tuning around.
Move the pointer and click on the new signal to answer. The 2.5 is a
"mini-band" by consensus. The audio out in reality is an IF.
So there are rules to keep things nice in the 2.5. One of them is to run
little enough power so you don't push down other signals in the passband by
hitting RX AGC's, AND so you don't add power to the inevitable IMD products
in one's own TX.
Power for PSK does seem to be such a waste, after watching a signal decode
perfectly that I could not hear in the passband noise with my ears.
PSK is kind of like living in an apartment building with thin walls. For
decorum and peace, need to keep the levels down.
