You *can* hook up your Eico 720 Tx and see its CW rise and fall times and perhaps use that information to dig into the radio and improve it.

You've GOT to be kidding -- CW waveshaping is spectacularly good already. If it ain't broke, don't try to fix it! And, last I heard, Wayne has the code locked up so it cannot be screwed up.

Besides, the time domain (rise/fall times) is the wrong way to look at keying. The only effective way is in the frequency domain, where the P3 with SVGA can resolve to a few Hz when set for narrow scan widths.
