Novel SSB transceiver Design with only Seven Transistors

When Pete Juliano N6QW sat down to design a sideband transceiver for the 20 Meter (14 MHz) ham radio band, he eschewed the popular circuits that makeup so many designs. He forged ahead, building a novel design that he calls Pete’s Simple Seven SSB Transceiver, or PSSST for short.

What makes the PSSST so simple is not only its construction but the low component count. The same circuit using four 2N2222A’s is used on both transmit and receive.
