[DSP-10] CW transmit has a raspy sound

[Ron Meiring]

Hi Lee,

I have got the same audio. If I turn down the modulation, I got 
almost no output. Still sounds raspy. However I need to keep almost 
constant audio to get some real output. 
All DC points where good here. Mic Settings are also good.(this is 
not a mic setting or overmodulation problem) 
My feeling, is that one amp stage is not linear, or there was an MMIC 
marked wrong in the kit ?? Or we both put an MMIC in the wrong spot 
...I am just quessing .... 

Cheers
