Hey guys, I live in the Houston area and have a 3.872 Valentine 1. Recently I've noticed that the range on my V1 has been lacking greatly, I've already sent it in for a tune-up and still the same thing. I have it in little l with X and POP off. Other then that, I have the auto-muting set on 6 dots. Furthermore, I have it mounted up high next to my RVM. Any help would be appreciated!!
