40/80 continues
My friend and I designed the 40/80 in 2018. We used NE612 for the mixers and a logic chip for the oscillator. It was a unique design and worked well. Today I start on a new version using all discrete components. A TUN RF amp, Gilbert cell for the mixers, LAMBDA diodes oscillators and a TUN AF amp.
