I've noticed them a few times in the last few weeks. My "20" is a few
miles south of the Pentagon, where I maintain a VHF listening post to
monitor air traffic at Andrews AFB - AF1, Marine1, that sort of stuff.
I generally hear them between 2000 and 2100 UTC, which is 3 p.m. to 4
p.m. EST.

The first time I heard them, a few weeks ago, I thought they were
Australian, from the accents. They play pop music. They remind me of a
station I used to listen to twenty years ago. I think it was called
"Radio 5," something like that. They were in Capetown, and I used to
hear them about 1 a.m. on the east coast of the US. That would be the
middle of the day in RSA. They were especially strong in the winter.

Primetime says CVC International is in Zambia. It also says the
broadcasts are aimed at Africa, so the electromagnetic wave thingies
are flying a right far piece beyond the target audience.

Google also comes up with these hits:

Online Music, Shortwave Radio, Streaming Media - CVC.TV

The website says the target area is NW Africa. Why they would be
broadcasting in English to that region, I do not know, as it is
largely Francophone.

Please give them a listen. See what you think.
