Got home tonight and thought I'd look into all this before I go to bed.

According to the service manual I need a 1uV signal from the generator at 30% modulation to set the signal to noise level. And looking at the charts I see that it would be -106dbm. So that means to set all my attenuator switches in the IN position and the fine adjust at -10.

At this point I and the radio don't hear anything!

Maybe I'm not understanding this as well as I thought. I'll go read everything again and see where I messed up but...

Can someone agree or disagree with these numbers for me?

OK, I am hearing it and the radio does too. I Googled a 1khz tone and its not the same tone my generator is putting out. And its also not a 400hz tone. Its between them. I looked at the program Robb posted up and it has the ability to change the tone so maybe I can fine tune it to be the same my generator is putting out.

Tomorrow I will open up the generator and see what has been done to it as far as tone mods. Maybe I can adjust it. We will see.

BTW, I did it by ear again but don't think it helped. I'll compare it to the program tomorrow and post what happens.
