Thought I would share some settings on playing with a mic pre-amp with the Bitx40.
I am using a
So far its working ok at best I sound a bit robotish.
The audio file is from Michigan to Milford PA
I am TXing at around 20w with my amp.
I took the audio out through a 10uf dc blocking cap to the bitx40 mic in.
I powered the board from a 9v just for testing.
R136 is about 1/4. If you use a pre-amp you should adjust this lower or you will cause one heck of a noise on tx.
I am not yelling or shouting to get audio out now but not sure I like the audio in any case.
