Wayne,
If the user has a P3 connected, please consider the addition of
something on the P3 to indicate split. Most of my eye action is on the
P3 in a pileup, not on the frequency.

Thus the "NON.SPLT" or "SPLIT" would come on when you key, and stay on for at least 300 ms, the timer being retriggered each time you key. To get an idea of what that would look like, just watch the RX and TX metering scales as you key the radio.
