    Amp Keyer Amplifier Interface. Retired now and thinning out the shack. Use your new rig to key an old linear amplifier. Many older linear amps require a higher contact voltage and current rating to key an amp than is built into the newer rigs. This device solves that problem. Made by the Heathkit Shop/Sunlight Energy Systems. Fully functional, no dings, no dents....looks brand new....will include the cables that I used with it to interface my Yaesu FT1000mp MkV to a Colling 30l1. No DOA .....$40 Shipped to CONUS. Paypal preferred. Thanks, Pete

    External Amplifier Keying for Solid State Rigs:

    Trying to interface a transceiver built in 2003 with a amplifier
    built in 1969 can generate all kinds of problems. In the old days,
    the transceiver had a separate pair of relay contacts
    that were used to "key up"
    the amplifier. Today, that relay has been replaced with a
    surface mount transistor that
    can only switch 100 Ma at best. Plug in your SB-220 into
    that radio and puff! It’s
    time to call 1-800-FIXME.
    The AmpKeyer is a small interface that will
    allow you to key that SB-220 amplifier with
    your new Icom, Kenwood, Yaesu or Ten Tec
    radios. Don’t have a SB-220. Not a
    problem with the AmpKeyer. It will work with ANY amplifier that
    I know of. Dentron, Heathkit, Hallicrafters, it makes
    no difference. New or old, the AmpKeyer keys them all.
    The key line from your radio is coupled to
    the amplifier via a optical interface. The
    AmpKeyer will switch up to 10 amps, (yup!) at 12 volts to ground.
    If you need a set of insulated contacts for use with the -130 volts
    bias Heathkit requires, the AmpKeyer can
    handle that too with its dry relay contacts.
    Why there’s even a grid blocked output if you
    ever need that too!
    A built-in standby operate switch can control
    your amplifier if need be. Now you can
    leave your Heathkit SB-220 or SB-200 on all
    the time and let the AmpKeyer set the
    amplifier into standby condition. A front panel
    mounted LED lets you know what the
    status is of the amplifier.
    Three bright green LEDS let the operator know
    there is power to the AmpKeyer, if the amplifier
    is being keyed and the status of the standby/operate switch.
    All connections to and from the radio and
    amplifier are RCA type jacks. The interface
    cables are easy to obtain from Radio Shack.
    The AmpKey operates from any 8 to 18 vol
    t supply either ACor DC input.
    TheAmpKeyer will automatically set the polarity and the voltage.
