This thread is to discuss the use of a buffer amplifier to provide isolation between the radio discriminator circuitry and the microphone or line input to a computer.
Here's a circuit I'm thinking about building. The novelty of this one is that it is a single transistor design - no op-amps. It's actually a guitar pre-amp circuit.
