<div class="moz-cite-prefix">To add to what Corey suggested, any
time I see a post that indicates the repeater as tinny audio,
the first thing I suspect is the audio is double -
pre-emphasized. <br>
<br>
This can happen two ways:<br>
The audio feeding the transmitter is already pre-emphasized, but
the transmitter is doing it again. Audio placed in to the MIC
input will almost always add pre-emphasis to the applied audio.
If you are feeding a radio that applies the pre-emphasis as part
of the hardware, then don't add pre-emphasis in the
configuration file.<br>
<br>
It can also happen with some hardware (no necessarily app_rpt)
when the receiver audio never gets de-emphasized and that audio
is fed to a transmitter that applies pre-emphasis as part of the
hardware. <br>
<br>
Both of these will result in double pre-emphasis and the audio
will sound tinny.<br>

as to if there are any settings in the dial setup that
would make the sound have more bass, I have 2 nodes using
icom icf-f121<br>
Radios and one using a Motorola gm300 and they all sound
fine, the other node is using an old Marconi Marcom vi and
the audio it transmits back to the repeater is very
tinny... The audio it sends out over the network is really
nice. Just wondering if there are different settings for
different style audio<br>
Thanks<br>
