Right after Elecraft announced the K4 line, I was interested, having owned a K3, then K3s, along with many of their kits and other do-dads. But at the time, I figured it would take years for the K4 to become real, and bought a FlexRadio Flex6600M instead (which served me well as a remote radio).
Last night, UPS delivered a K4D to my door, and after much moving, cleaning, and groaning about changing my shack, I got it installed this afternoon.
It took me about 2 minutes to figure out how to enable the internal tuner, and change the TX power. After that, a quick “TEST DE WB4SON” on 40-meters, and I was on the air!
