Maybe my interest to QRP is partially because K2. I want to use my K3/100 still quite a lot in QRP and QRPP. The degree of adjust is really fine down to 0.1W. Also, 100W PA switch-off below 10W is very clever. But to crank between 100 and 5W is not very handy. I would like to see PF1 to change powers between two adjustable levels. Benny oh9nb
