CPD is spaced usually 6MHz apart, as you can tell from the pic this is more than 6MHz. The tall spikes you see in the picture is the first time I have seen them. But the echo of the 3.2MHz of bandwidth allocated to the modems with the center frequency at 22.5MHz comes and goes every 3 or 4 months. Today I checked and the reflection, or echo is gone, and will probably not be back for a while.
Has anyone seen anything like this before?
I have seen CPD many times before, but I don't believe this is CPD here.
