Over the past year, maybe even longer I have been hearing a station broadcasting music and what sounds like a commentary on 28.385 AM. I am assuming it's coming from somewhere in South America as I get the strongest signal when pointing the tri-bander to the south. I'm currently listening to it as I type this post at 16:15 zulu with a barely audible signal. I'm not sure if they are speaking Spanish or Portuguese. It almost sounds like a talk radio show as it generally has music or periods of music mixed with someone talking as of they are giving out news or a commentary. I guess it could be a pirate station as well. I was just curious if anyone else has notice it before? Browsed around on a few shortwave forums lately and never really came up with anything. The curiosity lingers.

Maybe the 3rd harmonic of 9460, a valid BC freq? 
Let's hope 10 meters doesn't attract pirate stations.

According to short-wave.info, there's nothing on 9460 at 1615Z.  It's mostly used by China Radio Int'l, plus a few other Asian broadcasters, plus a couple of BBC relays in Africa.  No South American stations on 9455 or 9465 either.

28385 is also the 6th harmonic of 4730 kHz.  There's a station in Bolivia on 4732, but it's not shown as being on the air at that time.

Pirate, or a harmonic thereof?

Apart from the truckers and bootleggers who already invade it?

Possible that it could be a harmonic. I haven't heard it often enough to really have a chance to investigate it in more detail. That will probably be the next thing I do. Interesting to say the least.

Possibly a Spanish-speaking FM station? Could it be a harmonic of an FM stn, anybody care to whip out a calculator? I know that my Icom gets swamped with FM harmonics when FM mode is on (IC-735).

Probably overload, not harmonics (which would be in the upper-VHF and UHF range).  I have the same problem with my Grudig Satellit 750, even though I'm 30 miles away from the South Mountain tower farm in Phoenix.  I find an FM trap is mandatory.

Over the past year, maybe even longer I have been hearing a station broadcasting music ... on 28.385 AM. ... it's coming from somewhere in South America . It almost sounds like a talk radio show as it generally has music or periods of music mixed with someone talking ...

I also hear it just about anytime 10 meters is open to SA.

Seems to be some kind of religious format with a LOT of slow piano music.

FWIW,..... I am only about 80 miles North of you
