Just worked this island south of mainland Chile on 10 meters.
They were 59 for a short time here in Ohio.
Penquin country, DX for a fairly new ham.
I have read he is not an licensed amateur. The claim is he's a CBer using 10 meters.
No other Chilean ham's call follows that format. BTW, I have worked him too but will no longer work him unless somebody gives me substantial proof he is an amateur.
