Re: weak mic audio output,


Ion Petroianu, VA3NOI
 

I have redrawn the schematic with modern, through hole components and recalculate the LPF for low impedance.

I designed a PCB using Eagle freeware.

Please check for any mistakes.

I plan to order boards and will have around 10 available.

Check in files under my call sign.
