JBOT – An Easy QRP linear amplifier

During a morning chat, N2MCS mentioned that he was looking at a simple QRP linear amplifier design and gave me the following url:

JBOT – An Easy QRP linear amplifier

It was designed by Ashar Farhan, VU2ESE, who is perhaps better known as the designer of the rather popular BitX20 rig. The amplifier takes a single milliwatt up to a QRP gallon, and uses only bipolar transistors. Definitely interesting.
