20 Meter 20 Watt Linear QRP Amplifier Kit * Works great with Ramsey QRP rigs, or any other 1-2W transmitter * Built in T/R relay automatically switches between RX and TX * Operates all modes...CW, SSB or AM Need a little extra boost for your QRP rig? This nifty little amplifier may be all you need. Believe it or not 20 watts is only 7db (about one S unit!) less power than a full sized commercial transceiver. These compact amplifiers are easily driven by any of our QRP transmitters or any other unit in the 1/2-2 watt range. Advanced power MOSFETs are used for the utmost in efficiency and purity, while a multistage low pass filter is used to assure a clean signal output. Power required is only 12 VDC at 2 to 4 amps, depending upon power output. Complete step-by-step instructions are provided which makes building the kit a breeze. The amplifier works well for all modes: CW, SSB and AM. Case included. Be sure to check my other listings! I carry components such as capacitor kits, semiconductors, tubes (NOS and New), hobby kits, and other electronic supplies.
