Mystery signal 408 KHZ

[KEV200]

Last night at 08:05Z picked up CW signal "8502" on 408 or 409 khz, repeated over and over again. Not your usual beacon ID and not an image. Anyone else hear this?

I live in NC, will try to pick it up and translate it. I work nights but will be off for the next 4 nights so I will
give it a try. I can switch between N to S and E to W dipoles, maybe we can determine where it comes
from.
