Running 13.8v on 30a ps. Running into dummy load. Each band the meter on radio reads 10w higher than external power meter.? The meter cal will not let me adjust down to 20watts to match external power meter as cal procedure indicates.? I turn function know ccw it increases radio power meter reading if I turn cw it decreases but only to 30w. If I look at the user settings ini the bridge is 100. If I change to 70 radio power reading goes to 66w with external power meter reading of 20w. All this happened after last update
