Amplifier Keying Interface Cable
Ameritron ARB-704 Amplifier Keying Interface Cables are designed to interconnect only the Ameritron ARB-704 Amplifier Keying Interface to virtually any modern-age transceiver, so your radio will be able to safely key almost any amplifier.
These ARB-704 interface cables are available in a variety of plug and play configurations to connect your specific transceiver model to the ARB-704. They may only be used with an ARB-704 and cannot be used for connecting a radio directly to an amplifier. Besides, you will want to use an ARB-704 Interface as low-cost insurance against any amplifier keying pulse from damaging your radio!
Use an ARB-704 to protect your radio, and then order Ameritron ARB-704 Amplifier Keying Interface Cables from DX Engineering for each of your transceivers!
