I have been WSPRing on 6m all morning. I didn't see any stations at all. I use a loft mounted halo, so not brilliant, but at least its omnidirectional.
I have just resurrected another laptop from retirement. I'm still assessing how good the clock is, but it has been ok for several hours. I can now run two stations, presently 6m and 30m, although 6m is off right now. In principle I would like to do some serious measurements at 6m, always a band that has fascinated me, but it does need some responses.
