This morning I fired up my Elecraft K1 CW transceiver not having used it for some time. It is such a good little rig. Mine has the 4 band unit and internal ATU option and covers 40, 30, 20 and 15m. The filtering is excellent and the user interface good as long as you can remember the menu system, which I forget often when I don't use the rig for a time.Within a few minutes of connecting the end-fed wire about 15m long into the back of the rig I had 5 QSOs in the log on 40 and 15m. It is such a perfect CW rig.
