IF YOU CAN'T BUY IT, BUILD IT !

If you own a newer Icom HF transceiver and an older HF amplifier, you need an external buffer relay circuit to key your amp. While there are commercially made adapters such as MFJ's unit, they require an external power source and adapter cables. 

This unit plugs into the 7-pin DIN ACC2 jack on the Icom transceiver via short shielded cable, and is housed in a small "Radio-Shack" style project box with RCA jacks for keying and alc, a pwr led, and a transmit LED. It utilizes a current-limiting resistor and diode to lmit the load on the radio's tx line, and an optocoupler IC to totally isolate the amp from the transceiver. 

For newer amps with a lower positive-voltage relay (<= +30vDC/125mA), the amp's relay can be connected directly to the IC. This is ideal for QSK and provides quiet, all solid state, "no moving parts" operation. However, if you are using an older amp, such as an SB200 with -110vDC on the relay coil, then this project's interal relay is a must. An advantage of utilizing the relay is you will have a switching circuit that can be used with ANY amp, positive or negative keying, voltage and current handling limited only by the relay's contact specs. 

Another feature of this design is that I have brought ALL of the signals available at the Icom ACC2 jack into the project box for future expansion, such as band-tracking switching and transverter control applications.
