I have never QSOed on the 6m band, but last Sunday when I happened to watch on the band in the afternoon local time, I heard some VK stations for the first time.
I was using a dipole antenna for the 15m band, so I decided to add an element for the 6m band. It took me about five minutes or so to get ready to call, and at that time the signals were with heavy QSB. I called a couple of stations for several times, but only in vain.
I hope to contact some DX stations on the band next weekend.
