For those who think life is too short to do QRP all the time, here is what I did. I made an amplifier similar to the amp in Communication Concepts web page, specifically the Motorola EB-104 Amplifier (kit!) that uses 4 MRF-150 transistors. See www.communication-concepts.com/eb104.htm. I use 48 volts supply voltage and keep the 48 volts on all the time. I use the 8R line of the K2 with the keying circuit mentioned several times in this reflector. I built a set of low pass filters for the bands I operate, that is 40M, 20M and 17 M. I get about 500 watts out of the amplifier after the low pass filters and the relays. I use a 2 element wire beam up 35 feet so I don't have a huge signal but the audio compression in the K2 really helps a lot. It sure is nice to break a pileup on 20M phone with one call when the band is open to Africa!!
