Using the FT-1500 if you use the 6 pin Packet connector you will
have all the signals needed with enough drive to run most things.
Choose 1200 baud and let the radio do the tone decode if needed.<br>

style="font-size:12.0pt;font-family:Tahoma;color:black">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">
