That isn't true. PSK31 was invented by G3PLX and there was a waterfall in
his reference implementation of the mode, psk31sbw.exe. The innovation of
Digipan was to allow you to click on a signal in the waterfall and receive
or reply to it anywhere in the audio passband, whereas the G3PLX software
required you to tune the signal in to a specific frequency, rather like
using the built-in decoder in the K3.
