i cant tune the rf power down any lower than 5 or 6 watts am in the radio unless i turn my rf power knob down along with it , wich is fine its just a pain in the ass everytime i want to switch to ssb ,, because if i leave the rf power down from am and swich to ssb the amp wont turn on unless it swings from higher ,, can i run this at the 15 - 20 swing on ssb.. i do have a 3.5 inch fan mountted on it as well and seems to run cool. dims the hell out of my truck.. when i speak lol
