[arm-allstar] Allstar with a 900 MHz Quantar

I am in the process of interfacing Allstar to a 900 MHz Quantar.

I amrunning  Image Version 1.5rc2 with a DMK URI and a Northcomm 
Technologies cable connected to the 50 pin interface connector. Looking 
at the modulation levels on a service monitor, it appears to be a bit 
low running about 1.8 KHz.

This is with the TX level set to 900 and the internal 6 db amp in the 
URI in line. In looking at the mod scope, it does not appear that any 
limiting is taking place on the TX audio.

In the previous connection to a repeater controller, I had not problems 
achieving about 2.0 KHz which is what I like to see for 12.5 KHz 
bandwidth modulation.

Any input from those running Quantars would be appreciated.

Joe
