Would someone check menu #8-4 and compare tuned vs. flat on 80 and let me know if there is an increase or decrease in sensitivity. I'm having trouble understanding what this is supposed to do since the book doesn't really explain. I did note a large gain increase on 10 meters but a slight decrease on 80. Has anyone found any value to this feature? Steve Ellington N4LQ@IGLOU.COM Louisville, Ky
