[AMRadio] Apache

[Charlie Solie]

Pete is right about the Apache audio adjustments.  For those who might not have a manual, I have put a copy of page 7 at:

I have also made a block diagram of the system that should help folks understand the problem.  Both pots control the audio gain and if the level control is set high enough, the clipper will not do much if anything.

Note that R48 can be disconnected if you need higher audio input impedance.

I would like to, but have not tried the negative feedback.  Unfortunately, what has been described does not include all of the audio stages.  I wonder if the feed back point could be move toward the input?

73,

Charlie
