Description...
PLEASE NOTE: Ramsey has discontinued all their consumer kits. All of our QAMP kits are now sold out with no stock remaining.

For a little extra boost to get your QRP signal through the QRN/QRM, 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 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 input. 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.

We've built several QAMP kits. It was found that this is an easy one evening project. The instructions are easy to follow. The circuit board and components seemed to be good quality and the amp works good with SoftRock transceivers.
  • Works great with any 1/2-2W transmitter
  • Built in T/R relay automatically switches between RX and TX
  • Operates all modes...CW, SSB or AM
