Simple Homebrew SSB Transceiver Update

Work in progress to redesign the original homebrew SSB transceiver. Using an old Yaesu XF-32A crystal Filter (looking to change to XF-9X series to have CW and SSB) 3.180 MHz IF Homebrew DBM (1N914/4148s) - matched for forward voltage drop All transistors are 2N3904s. Toroids (excluding BPFs) are FT37-43s VFO/BFO is an arduino driving a Si5351 DDS Circuits are hand calculated (my trusty HP-48G!) then simulated and tuned using LTSpice
