I don't know if VOA could be considered a 'full service' SW broadcaster. It does offer varied programming, but has been cut back due to budget constraints lately.
I have heard segments on VOA about international radio broadcasting and the fellowship that international ham radio offers. The language barrier is less than it was now that there is software and 'apps' for that.
I think that any U.S. SW broadcaster would need to be subsidized as there is just not enough deep pockets out there for a privatized SW station. Some have tried and failed, but their intentions were good.
The 'fire and brimstone' and 'gold merchant infomercials' I can do without.
I do like WBCQ's programming during the week. They have discussed work on the station's Harris transmitter and antenna array when they shifted from 7.415 to 7.490 a few years back and have performed maintenance and fine tuning lately. Much of the programming is interesting and non-offensive. http://www.wbcq.com/?page_id=177
Glen Hauser's World of Radio did offer a Spanish language 'Mundo Radial' until 2007. http://www.worldofradio.com/
Ted Randall's QSO Radio Show is another SW program that I have enjoyed. They did a show on the grand old boatanchors of yore (which just happens to be my hobby). http://tedrandall.com/pages/home.php
I have heard ARRL outreach to youth in ham radio. It was on a commercial SW broadcast a couple of years ago and I didn't catch the station name.
Getting people engaged and talking can only be a good thing.
