This morning I awoke to find a strange entry in my WSPR log :

Timestamp Call MHz SNR Drift Grid Pwr Reporter RGrid km az
2018-11-15 06:34 CP3HAM 0.137491 -27 0 NJ00 200 N4BBQ EM84bm 15815 339

In a database query, I find that no one else has this station spotted. The call does not show up on a Google search. And the grid square is southern to the tip of India in the middle of the ocean.

Interesting...
