As I am considering selling my Elecraft K1 rig to fund some other purchases, I decided to fire it up this afternoon to see that all was well. It turned out to be a very pleasant QRP session with 8 QSOs in 8 countries in the log at 5W on 40m and 20m in a casual hour or so of operating. In addition, there is a page full of reverse beacon spots for the CQ calls that didn't get answered. With the Par 10/20/40 end-fed antenna it doesn't need much to match the antenna: in fact without the auto-ATU it should match well on 40 and 20m, although with the internal auto-ATU I can also match this on 30 and 15m.
I still have mixed feelings about parting with this rig: it doesn't get used much so really would be better with someone who would make full use of it. On the other hand, when I use it I get good results and plenty of QSOs. We'll see if it goes or stays in the coming days. It will be on eBay if being sold, but not until I've carefully thought about it.
