Not much on SSB, unless you talk slow and clearly especially with
a southern USA accent.
A noticeable amount on CW, especially when in contests.
Adding the bias system hurts nothing, and helps reduce heat.
When the amp is on and it's 80 degrees outside, I appreciate even
a few hundred watts less average heat. Near the north pole, I would
view the problem quite differently.
