Since the S/N is being reported have a radial button 🔘 to select if you want VARAC to control the power output of your radio with thresholds so you can set the max and min power that VARAC is allowed to move your power output So if you're have a extremely strong signal you allow VARAC to throttle back if during the process you get weak it throttles back up in 20% steps untill S/N is good or you reached max output level
