I keep seeing mention about changing the resistors in the KX1 to get higher power. Where can I find the information about this. I have looked on the Tech page at Elecraft but found nothing about this. My KX1 is working great with the power about 3.2 watts on 40 and 3.0 watts on 20. Wondering if this mod will give me closer to 4 watts. Aron NN1F Bedford, NH KX-1 #341 K1 #497 K2 #1555
