NEWBIE Question! Any Mods/Adds Needed for This Setup

I've had good luck out of my little KL 300 I run in the pick up. Did have some mods done to it though because I didn't like how the switches were set up. It will swing up to about 170 watts on AM if I remember correctly, seems like it dead keyed about 120 or so. I always run it on low. I just got a new (to me) Black Cat meter, I should check it again and see if I remember correctly!
