AM mode transmission can allow for asymmetry between positive and negative modulation percentage. While negative peak modulation must be limited to 100% to prevent the AM carrier from being cutoff, positive modulation percentage can peak as high as 150 percent without splatter or great distortion. The FCC AM broadcast standard is to allow upwards of 125 percent positive modulation of a carrier. My feature request is allow a control for AM modulation to allow a variable amount of positive peak modulation between 100 and 150 percent while limiting negative peaks to 100 percent. The control does not need to be on the front panel but may be made available in an audio processing submenu as it does not need to be adjusted frequently. K1VL

Start by locating the AM transmit modulation path and the audio processing submenu described in the request. Determine where negative peaks are limited and how a positive modulation control could be exposed; done means variable positive peaks from 100% to 150% while negative peaks remain capped at 100%.
