Attached is a revised circuit. Just 1 part has changed value (470n on the input to the first audio stage). For clarification, the caps feeding the PC mic input are 100n. Just for clarity I have made it clear this is my design G3XBM R.Lapthorn following the comment below by John Desmond EI7GL.
A proper CAD schematic will follow shortly.

Just a suggestion Roger. Make sure to put your callsign on the circuit diagram so everyone knows who designed it if the drawing gets copied or posted elsewhere.
Thanks John. Schematic changed!
