I worked Olivier prior to him being swamped by contest stations and I think he was calling CQ SOTA - but I agree the IOTA reference and the posting on the web page that Peter, G4ISJ kindly posted suggests this is NOT a SOTA activation! Rats! F/AM-070 is a 10 point, not yet activated summit! I also heard F4DLD/P on 40m - I wonder if the spot could be with a wrong callsign, not wrong summit (wishful thinking …).
F1SMV/P was also spotted on the same Summit.
This does look rather suspect!
If I hear Olivier again through the contest QRM, I’ll ask him whether he is on an island(in/near a lighthouse) or on a Summit and report back here.
P.S. Just saw Manuel EA2DT has spotted that this is an IOTA, not a SOTA station.
