Regency Monitoradio/Executive Scanner M# ACT-E-10 H/L/U

I picked one up for $6, all the lights light up and the squelch apparently works. The channels change and scan like normal. Both antennas are there but turn when you twist them, I figured that they would screw in and out. They do not come out but kind of just sit in there slightly loose, they are not bent or broken.



I can't get any signals, I live in a major city in the U.S. and expected something. Should I open it up and check the crystals or something? How would I do that?
