About halfway between Brazil and Africa is Ascension.
W6NV, W6XD and N6AA are apparently there for Sweepstakes. I heard them on 40 but they switched to 80M before I had the chance to complete a contact. So I switched to 80 to give that new vertical a whirl. I listened to Oliver work some stations and made my stand to call him at the top of the pileup and I guessed right as he came right back.
Nice S7 (-80 dBm) signal with a band noise down about S2 (-110 dBm). I think it's going to be a good DX season.
