Hello Gang: I just finished my K1-4 today, SN 1476 and wow am I impressed. It's great to be back on QRP after a long absence. Look for me on 40, 20 & 17 until I get a 30 mtr antenna up. Many thanks to the staff at Elecraft for great customer service in answering some questions. Construction was a breeze except for one mistake on my part (dyslexic diode placement)! 73 & CU Cormac, W7JHS
