I don't think these radios will exhibit the loud modulation and "swing" that many CB ops look for in a radio. If you want a louder sounding base radio, the Galaxy DX 2547 is the way to go.
That said, there isn't anything wrong with these 1000 style CBs, it's just that you probably won't get a lot of punch from them. Back in the beginning of the CDX contests, I used to run a Comanche Warrior 10 meter version of these radios (got it for $129 from National Communications back then!) , and with a small helper behind it, I worked all the members and it sounded fine. One of our locals ops uses the Warrior now for his local ragchewing, because it has a more pleasing sound for ragchewing, but if he works DX, he goes with his President Madison because it has more bark.
Don't expect big audio from it, but it does have it's place.
