The K3S works just fine on FT modes. I had my line level set for 11 but today I had to crank my line level way up to get the same output level. I've made no changes that I'm aware of. My Line out goes to the micro Keyer II Any suggestions as to why and how to fix? I'm using a micro Keyer II with software version 9.2.2 Pete, W1RM W1RM at Comcast.net
