What's on 6055 @ 0000?
 

For the last two days, there's been a signal overwhelming Spain's 0000
broadcast on 6055. In AM it sounds like a *wooooooo* sound. In USB it
sounds like a data signal. I can almost null it with LSB, but not enough
to make REE readable. A quick check revealed that it's only on 6055.
Could this be a US military op?
