The manual lies.
Well, sort of. It won't do RIT increments - it will do absolute values.
The Kenwood has a command that says "bump the RIT up (or down) by one
count". The Yaesu requires you to read the RIT, increment/decrement
the value, and then send a new value out. This takes WAY too long to
be useful.
