    HardRock 50 amp with the ATU installed also includes the KX2/KX3 Hardrock50 Interface with cables. Amp works seamlessly with the KX3/KX2. Works with QRP rigs like the HW7&8, and Tentec Argonaut. Also works with FT 817/818, ELAD FDM Duo and SDRs like the Flex 1500, Genesis, Softrocks and anything that runs PowerSDR, HDSDR and the OmniRig interface.
    -60M band coverage. The ATU has a 60M low pass filter which provides sufficient attenuation of harmonics for legal operation on the 60M band.
    - Wattmeter mode: The HR50 amp will function as a stand-alone wattmeter reading forward and reflected average power, forward peak power and SWR from 0.1 to 50W. - QRP mode: The amp keys up and provides ATU functions but does not engage the power amplifier stage allowing the ATU to function with the exciter barefoot.
    - ATU has auto Band Select Support for Elecraft KX2/3, and other radios previously mentioned.

    The KX2/KX3 to HARDROCK-50 Interface kit takes the work out of connecting your Elecraft KX2 or KX3 radio to the HARDROCK-50 for automatic band following and Push-To-Talk. The breakout board provides plugs for KXUSB, KX3-ACC1, KX3-ACC2 and KX2-ACC. Simply plug the interface board into the ACC DB9 plug on the HARDROCK-50, connect up the provided cables to your transceiver and you are ready to go.

    Amp is in excellent condition, from a no pets, smoke free home.

    $375 shipped from Savannah, Ga. PayPal OK. Additional Photos upon request.
