Yesterday I make some major fixes on my sound card settings. And after some tests I think that now they should be OK: QRP or even QRPp signals travel around the world easily on 30 meters band as shown in the picture below.
Last night and this morning I have run only 1 W or less with my Icom IC-703 and vertical antenna. Amazing how well they work.
