Motorola XTS 2500I Model III With Horrible Audio on TX

[madfrenchie]

Hello,

I recently purchased a Motorola XTS 2500I Model III and have been having some issues with the transmitter audio quality.

The quality of the audio transmitted is what i am having problems with. My voice ends up sounding very low in level with ALOT of bass, of course the louder i place the volume, the louder this soft bassy voice gets. If i use another TX radio with the same RX radio, all sounds great, so i know the issue is with the TXing radio. *Different RX Radios have been tried*

For explanation purposes I will provide you with the radios i used during the test.

Transmitting radio - XTS 2500I
Receiving radio - GP380 <----I have never had any problems with this radio and have tried with other makes / models as receive radio,

I am using a conventional personality set to Wide band. The TX/RX simplex frequency I am using is 151.895
There is no PL codes on TX/RX set at all.

In the radio wide configuration I have tried both ways, with the Automatic Gain checked, as well as it not checked with all zeros. Both configurations had the same result.

I'm thinking its a hardware issue, Unfortunately there is no way for me to get a remote mic to test that out.

So whats my question, is there something in the setting I am missing? I did look at the channel spacing, and set it for 7.5. what other tests can i try, apart from trying to get my hands on a speaker mic, which i can't do.

I do have a 1200 mAh battery instead of the larger 1500 mAh battery they recommend, is it at all possible that this would affect the quality of audio on TX. This radio does a great job of receiving audio! crisp and clear!!

Thank you ahead of time to anyone who can help!

Get a complete alignment done on the radio and go from there..

Is your transmit emphasis box checked? If not it should be.

Also I have to second what Marc said on the complete alignment, especially if the radio is a 123ABC1234 unit.

Hey, thanx guys for the response,

The problem is i don't have access to the equipment needed to perform an alignment.

The radio is not a 123ABC1234 unit, its a legit unit.

Now as far as the TX Emphasis, I thought that it should only be enabled if the receiving radio is compatible and has the Rx Deemphasis or what not enabled??
