President lincoln/ hr2510 weak receive

So hopefully I have this in the right place but here goes. I have a lincoln that has very weak receive and when I say weak I mean about 100 yards and that's it. On am if you turn the volume all the way up you can hear vary faint static. On USB lsb cw it's a little louder and fm you have plenty of static. Like I said though if your not within 100 yards of it you can't pick any signal. I know it's not antenna or coax anything external. I've had it to a shop he wasn't too familiar with this...
