 **The digital window: what N1MM has and this does not.** The window is here —
-receive pane, coloured callsigns, grab list, call stacking, twenty-four macro
-buttons, the engine controls — and the function keys, ESM and the QTC window
-send through the engine on a digital mode. Left out: the waterfall, the spectrum
-and the XY scope, which the engine reports and nothing draws; more than one
-receive pane, which is MMVARI's multi-channel decoding rather than MMTTY's;
-sending a text file; and N1MM's Send All, which keys a whole QTC series at once.
-The other interfaces N1MM offers — fldigi, MMVARI, the hardware TNCs — are not
-here either, though `DigitalEngine` is the place to add them.

+The receive pane has been driven with a stand-in bridge that prints prepared
+text, which is how the printing, the colouring and the Letters/Figs box were
+checked. Nothing has been decoded from a real signal: this machine has no sound

 **Voice keying.** `MessageSender` was written to cover a voice keyer playing a
 recording, and nothing implements it. Each operator's recordings folder is
