Never mind, I found it on a different kiwi SDR, but thanks for the quick response. The KB0FX one is too noisy at that frequency to copy much of anything right now. But I figured it out. 14670/2 = 7335, which is a Radio Martí frequency. The jammer has a harmonic. It's not deliberate jamming of CHU, just more sloppiness from Cuba.

Correct. After reading the post a couple of times I believe that the intent was the Cuba was jamming Radio Marti.
