im guessing the one in Sao Paulo and the few in the neighboring towns can probably make it into Rio. Still, Rio should have its own Dance station, I heard Energy 97 in Sao Paulo does pretty well, and even it has a somewhat limited signal due to the Mountanous Terrain, and the Huge Size of the city. Ive been all through out Latin America, except for Equidor, and Venezuala, and I had trouble with Energy 97s signal in part of Sao Paulo, so I listened to their CHR Metro Fm when I couldnt get Energy. Metro FM has a Huge signal, can be received about 150 miles north of the city, especially if your up high, im not sure if they have any translator booster stations that I may have been receiving, or if it was still the Sao Paulo signal. Im sure I listened to Jovem Pan too, as their were a few stations that I picked up on different frequencys in different places, but because I dont speak Portugees, I couldnt positively ID the regional stations. I did here quite a bit of CHRs though, even in very rural Rain Forest Area's, most of which had a rock lean, and BTW, the local Rock from Brazil is very good, and so is the rock from Argentina. In Argentina I had alot of trouble getting stations to come in good, though the dial was over loaded, plenty of Dance friendly stations in Buenos Aires, some of which only cover 5-10 miles. Chille had a couple of Dance stations in and around Santiago, one or two of which where Modern Rock-Dance Hybrids, but I dont think any of them streamed.
