There is one reason and one reason only on God's green earth to reduce your carrier and enhance the radio's 'swing' on AM transmit.
An amplifier.
All linear amplifiers tend to exaggerate the carrier and diminish the peak power. Modding the radio to bring the carrier down so the amplifier isn't straining is half what's needed. Preserving the radios full peak modulated power when the carrier is reduced serves to counteract the amplifier's tendency to suppress those peaks.
Set up right, the radio should sound as good amplified as it does barefoot.
But for a radio you will use barefoot? Waste of time.
