This is my newest SSB transceiver dubbed the LBS-II. It is a single band for 40 Meters and has a 5 watt output. The size is 2.5 inches high by 4 inches wide and 7 inches deep. The IF is at 9.0 MHz using an INRAD model 351 four pole filter. The VFO and BFO signals are supplied using a Si5351 driven by an Arduino Pro-Mini. It took about 3 weeks to construct.
