When?

1, When you need 8 to 10 Volts of audio like driving a FM modulator 
directly (GE M2).
2, When you want the ability to revert to in-cabinet controls when the 
BBB blows up.
3, When you need the additional AF filtering because you are driving the 
modulator directly.
4, When you have the wrong polarity COS or CTCSS hardware logic and 
don't want to hack in a bunch of circuitry to correct for it.
5, When you absolutely don't want the transmitter keyed for days on end 
because Asterisk hung and the FOB is stuck in transmit.

That's when...
