ARB-704I2, AMP TO XCVR INTERFACE, FOR IC706O REQU.

Ameritron Amplifier-to-Transceiver Interface The ARB-704I2 will work with your all models of the ICOM IC-706 series, the IC-718, and the IC-7000. (PNP-13D is included) The ARB-704I2 will replace the current series of amplifier interface buffers(702I, 702I2, 702K, 702Y). The ARB-704I2 advanced interface is compatible with all common radios and amplifiers even though radios and amplifiers do not have standardized voltages, accessory plugs, or wiring. This interface is designed to work with any amplifier/radio combination. The input is designed to be compatible with any transmitter or transceiver, and the output is compatible with AC control lines or DC positive or negative amplifier control lines having up to 200 Volts peak open circuit voltage and 300 mA of operating current. Why you need the ARB-704I2 Amplifiers can damage radios if the amplifier has too much relay control voltage, voltage spikes, or excessive current on the relay control line. Such damage often appears as "stuck" or
