Why is the reception poor on my Radio Shack iScan 20-107?

Poor or no reception on your Radio Shack Radio can be caused by several factors. Weak signals from distant stations may require repositioning the radio and turning the SQUELCH control counter-clockwise. If you are too close to the transmitter, check performance with and without the attenuator activated to get the best reception. Also, inspect the antenna and connectors for any issues. Make sure that the proper modulation mode is selected for the type of system being monitored.
