<DIV>I found the following method to adjusst the the audio works the best</DIV>
<DIV> </DIV>
<DIV>1 set the TXA output to 5khz peak maximum by playing the status *70</DIV>
<DIV>IGNORE THE RX INPUT LEVEL UNTIL AFTER THIS IS DONE. </DIV>
<DIV> </DIV>
<DIV>This sets the official voice "ALLISON" TO BE YOUR LOUDEST
OUTPUT</DIV>
<DIV> </DIV>
<DIV>2 now adjust the receiver input </DIV>

<DIV dir=ltr><FONT color=#000000 face=Tahoma,sans-serif>I find that voice levels
are highly dependent on the person speaking, the rig they are using, the node
radio, and probably a dozen other factors. Generally setting the audio so
you see peaks just above 5 khz should be OK. Some radios have better limiting
than othesr and the peaks are well defined. On some you can see peaks go well
above what you would call max but the average is much lower. One thing you don't
want to do is have it set too high. Digital distortion is very annoying. I often
use iaxrpt's level meter for adjusting or looking at multiple users for
comparison. If you are filling the iaxrpt bar graph to 9o-95% without hitting
the edge you are good.<BR><BR>I often find that one node that shows 80% peaks
actually sounds louder than one that shows 95% peaks. Audio characteristics and
equalization can play games with your ears! I don't think setting using DTMF is
always a good idea because DTMF levels can be quite different than voice through
the microphone. <BR><BR>Some radios like the Chinese variety handhelds have
greatly varying audio levels depending on how far you are from the mic. You
almost have to eat the mic on some of them to have a decent level of audio and
then you have breath noise.<BR><BR>If you use a wide range of radios that you
use to talk to your node it is best to check them all. You may have to come up
with an average setting so that the loudest radio does not distort. <BR><BR>Talk
into the radios the way you would when you are not thinking. If you adjust it
talking right into the mic and then when you aren't thinking you usually talk 2
inches away the level is not going to be right.<BR><BR>In the future we hope to
have audio processing capability added to the code to help fix some of these
problems. <BR id=FontBreak></FONT><BR><B><FONT style="FONT-SIZE: 16pt" size=4>73

What should I see as I change input audio levels? Is there a recommended
FM<BR>> deviation? Is this the 3KHz and 5KHz? When I get it right, what
should the<BR>> display indicate?<BR>> <BR>> Thanks,<BR>>
