It's amazing how 30 metres can sometimes be dead then all of a sudden a lone piece of DX calls me. That happened recently when I put out a call on a dead band and a 9M6 in Malaysia came straight back. I've been having fun running 5 watts and getting reports back from South America too. So, 30M gets my thumbs up as a good band for DX.
For most of my amateur radio years, I ignored forty metres as a band where nothing interesting happens. However, over the past few years, I have become more friendly toward the band. I also operate CW on 40M but occasionally I plug the microphone in. This weekend, for example, 16-17th August 2014, I abandoned the Morse key and worked a few of the lighthouses on the air, which made a change. However, the best fun came when the band opened up in the early hours of 18th, when stateside starts coming in at 59+20Db. So I had a few QSO's running about 200 watts into my piece of wire. Then, I was lucky enough to be first on the scene when LU5FC came on (also 59+) so I grabbed him as well. I felt rather pleased with that.
