    dead key needs to be 2 watts if I remember correctly. I have the 300 watt version and I believe my dead key is 2 - 2 1/2 watts. I haven't checked it lately, but I believe I am right about that. I'm sure one of the tech will chime in and advise correctly.

    The dead key for any KL amp should be less than 2 watts for the longest amp life.

    The website lists 0.5 to 10 watts but i would stay under 3 watts. One more thing. If the mosfet amplifiers such as this are as picky as the mosfet radios you better make double sure your SWR is low or you will start blowing mosfets!

    The 203 works best with 1.5-2w input
