You *can* hook up your Eico 720 Tx and see its CW rise and fall times

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.
Easy Jim,
The Eico 720 is a transmitter. I believe Lyle is talking about using the
P3 TX Monitor feature to look at its CW waveform.
