 Im running a 100 watt SSB radio into a Proam 20 meter Hamstick antenna. My question is this; on CW it pushes forward 100 watts with 1:1 or less reflected.
on voice it will only peek forward about 20 watts with 10 being the norm. This seems low to me I can crank up the mike gain but its operating within factory specs and Im afraid of distortion.
Is this normal?

You didn't say how you were measuring the output power, but an average reading of 20 watts give or take is about right for a 100 watt radio. You have to understand that the meter's dynamics will not allow it to see the peaks. It takes a special amplified meter to do that, and even then it is not very accurate due to differences in voice patterns. About all you do when you turn up the microphone gain is increase the distortion in the signal. Set the meter for ALC, and adjust the microphone gain to a point the meter OCCASIONALLY comes off the peg.
