Bearcat BC-210 I have an old Bearcat BC-210 scanner which seems to work well on the higher Frequencies however at 26.965 to 27.405 range for ch1-40 it will not scan. It's old and the backup battery is probably bad and it only has the small screw in antenna. It does have a place to plug in another antenna. The MFG is actually Electra Co. I want to use it to listen to comments on local road conditions and police and emergency local broadcast. Thanks for the help Regards

The Bearcat 210 Manual specifically states that the lowest freq available is 32MHz.
