Re: The new uBITX boards are here
Jerry, The problem is the input impedance is the aggregate of the Miller and fixed (gate capacitance). That means two things, it changes with voltage and power out (voltage swing at the drain) and

Alison, My main interest was in demodulation. With its full HF coverage lack of proper AM detector seems a major feature lacking in the rig. NBFM comes as bonus with this chip. TDA1220 has an
