Curious 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
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
Thanks

Did you see this in the usbradio.conf?
txprelim = no ; Audio processing on left output channel: no,yes
; no - Audio is not pre-emphasized and limited.
; Suitable for use on a microphone input
; yes - Audio is pre-emphasized and limited.
; Suitable for direct connection to an FM modulator

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.
This can happen two ways:
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.
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.
Both of these will result in double pre-emphasis and the audio will sound tinny.

I think you just hit the nail on the head, this is the only radio taking audio through the mic connector, I will post my results after I try it out tonight
