• Amplifier interface ARB-704I2 for amateur radio

The ARB-704I2 will work with your all models of the ICOM IC-706 series, the IC-718, IC-7000, and the IC-7100. (PNP-13D is included). The ARB-704I2 will replace the current series of amplifier interface buffers(702I, 702I2, 702K, 702Y). The ARB-704I2 amplifier interface is compatible with all popular amateur radios and amplifiers, even though radios and amplifiers do not have standard voltages, by-catches or cabling. This interface is designed to work with any amplifier / radio combination. The input is designed to be compatible with any transmitter or amateur radio, and the output is compatible with AC control lines or positive or negative DC amplifier control lines with a maximum voltage of 200 volts in open circuit and 300 volts. mA operating current. Why Do You Need the Ameritron ARB-704I2 Interface: Amplifiers can damage your amateur radio if the amplifier has too much relay control voltage, voltage spikes, or excessive current on the relay control line. Such damage often appears as "sticky" or "sticky" transmission relays in exciters or short-circuit transistors on transmission control lines. In most cases where the amateur radio is damaged, the system transmits normally, but the external amplifier remains locked in "transmit" mode. This prevents the receive signals from passing through the amplifier at normal levels when the amplifier is in the "ON" or "OPERATE" position. The ARB-704I2 interface works with transmitters or amateur radio that bring the control lines of the amplifier to ground, or emit a wide range of positive or negative control voltages. The transmitter only switches currents of 0.35 milliamps and very low voltages when using ARB-704I2. It works with any relay voltage(AC, positive or negative) up to 200 peak volts and any relay current up to 300 mA. The ARB-704I2 is fully compatible with conventional amplifier relay systems. It is especially suited for buffering vacuum relay QSK amplifiers, since the ARB-704I2 does not affect attack or release times in a deleterious manner.
