Profile: Karter Electronics specializes in the design and development of electronic components. Our product line includes Simpeater simplex repeater adapter, RP30 battery charger, and RP60 CTCSS/selective call controller. Our simplex repeater is a device for extending radio range without the need for a second frequency. It achieves this by recording an incoming message, and then replaying it. The Simpeater features digital recording coupled with microprocessor control in such a way that it offers high audio quality, and simple installation and operation. Our RP30 is a six channel battery charger & conditioner suitable for use with a wide variety of mobile radio batteries. The charger uses a patented charging technique known as reflex charging.
