Tom, the full ultra light is reported to work on 160. It will handle legal
limit. I don't know how much power you get out of your al-600. Certainly
not 600 watts DC. If the 8x is working in Co, it will probably work in Mi.
You're not running full duty cycle, unless you are going digital or trying
AM phone. Others might know more on this topic. I am assuming you want to
run 160/6 meters?
