When I dial up, or down rf output, it takes in excess of 30 seconds to reach the output level, which is much lower than requested. 3 "bars" on the rf meter. That looks to be 20 to 25 watts. If I readjust the level, up or down, it takes another 30+ seconds and it will not go over 3 "bars". Anyone offer any suggestions? Thanks. 73. John. ve7day.
