Hi Mark,

The Handbook actually does not show a good waveform. That waveform has sharp
corners, and it would click.

Here is a better one:

That picture is a FT1000D with a click mod. It is the best waveform I have
seen in any radio.

It is important the waveform have absolutely no sharp edges or abrupt
transitions, and that the time be 4mS or longer.
