Add-on Electronic Bias System . . . $39 95 for AL-80A/82/1200/1500 Amps EBS-1, $39.95. EBS reduces heat by reducing quiescent current to low values during periods when exciter output falls below 100 mW. Features remote detector board. EBS-1H, $49.95, for other amplifiers. Call 662-323-8211 for details. ICP-120/240 Inrush Current Protector . . . $79 Stops power-up inrush current and absorbs momentary high voltage spikes to protect your amp, tubes and power supply components. By starting your linear amplifier through a high power current limiting resistor and then shorting the resistor with a relay, the start-up sequence is easier on your tube and power supply components. Avoids replacing expensive tubes and parts. Works with nearly all linear amplifiers. Limits current to 12 Amperes during heavy draw inrush period, 20 Amperes during continuous operating current. ICP-120, $79, for 120 Volt wired amplifiers. ICP-240, $79, for 240 Volt wired amplifiers. AMERITRON Amplifier-to-Transceiver Interface AMERITRON has the best selection of high power accessories!

AWM-35, $159 95 Amplifiers can damage radios if the amplifier has too much relay control voltage, voltage spikes, or excessive current on the relay control line. The ARB-704 advanced interface is compatible with all common radios and amplifiers even though radios and amplifiers do not have standardized voltages, accessory plugs, or wiring. Designed to work with any amp/radio combo. The input is designed to be compatible with any transmitter or transceiver, and the output is compatible with AC or DC positive or negative amplifier control lines having up to 200 Volts peak open circuit voltage and 300 mA of current. Operates with rigs that pull amplifier control lines to ground, or output a wide range of positive or negative control voltages. Dont take a chance! Get the ARB- 704 now! 4 1/4Wx1 3/4Hx2 3/4D . Power cord, 3 phono cords for relay/ALC/control included. Extra cable, $15.95 for following rigs: Model# Transceivers PNP-8D FT-1000, (MP), 900, 767GX, 920, 990, 747GX PNP-8M FT-890, 840, 817, 857, 897 PNP-35 FT-100, (D) PNP-5M FT-847 PNP-7D TS-440, 690, 450, 180, 140, 950, 130, 870, 2000, 50, 120, 530, 430, 830, 949, 570 PNP-13D All models of the IC-706 series PNP-7DK TS-930 PNP-7DK2 TS-520 PNP-8MK TS-480 PNP-5D FT-980 PNP-8DI ICOM ACC JACK ARB-704 $49 95 ARB-704I2 for IC-706s AMERITRON RCS-4 Remote Coax Switch Ameritron RCS-4 is a remote controlled coax switch that selects 1 of 4 outputs by supplying all control voltages through the coax. Elimination of control cables gives you a fast, neat and inexpensive installation -only 1 coax line for 4 antennas. You get two units the switching box (5 3/8Dx7Wx3H inches.) that can be tower, mast or wall mounted and the control console (6 1/8Dx5 1/4Wx 3 3/8H inches.) that is located at your operating station. The attractive indoor console has bright LED antenna selector indicators. A steel enclosure provides 100% shielding to prevent RFI and TVI. Switching time is 50 milliseconds. Teflon (R) SO-239 connectors provide reliable connections. The weatherproof switching box uses three heavy duty 16 ampere hermetically sealed relays on a rugged G-10 fiberglass circuit board. Quality components are used throughout the entire unit to ensure maximum life for the sometimes difficult-to-reach switching box. RCS-4 operates 120 VAC. RCS-4X for 220/240 VAC. RCS-4 allows safe operation with 14 Volts control voltage. Frequencies 1.5 60 MHz are covered by this excellent station accessory. Handles 2.5 killoWatts. Specifications: 4 pos.; Loss at 30 MHz less than 0.1 dB; VSWR is under 1.25:1, 1.5-60 MHz; Impedance: 50 Ohms; Power: 2.5 kW average continuous. Lightning Protected model RCS-4L, $179 RCS-4 $139 Suggested Retail A plug-and-play cable is not needed if your radio is not listed.
