You'd be surprised how little "power" matters on the amateur bands if only because of the lack of chaos compared to the disorganized havoc on CB. Yes, there are what are called "pileups" where rare stations are operating and stations "compete" to get an acknowledgement from him. A 100 watt station is usually adequate for most work on most all bands.

CWM is correctamundo. A point to made regarding the Tech license. You will have HF privileges on 10m from 28.300-28.500 with a 200w limit on power. Of course 10m is just as dead as 11m is right now. Hopefully things will pick up some in the next year or so.
