You might need to change the antenna. I used to have a center load all band antenna on my 106, and it picked up fine from my apartment at college (which I listen to 800 hertz), but when I went back to my home town, I could hardly pick up anything from my house (155 hertz) with that antenna. I bought a 800 hertz antenna to pick up better at college, which I really didnt need, and suprisingly I got a 75% increase on what I hear at home as well with this antenna, even though at home its not 800 hertz.
So try a different antenna on it.
I also find that in certain parts of my house I dont pick it up at all. IDK why this is, but I hear it fine in my kitchen but say the dinning room, I hear nothing.
