Astro Saber II - Volume difference between Analog & Digi

[Badboys2]

I have an UHF Astro Saber II that has both analog and digital channels programmed into the radio. The volume level on the digital channels are extremely low and I have to turn the volume all the way up to hear them at a moderate level. At the same setting, the volume level is extremely high on the analog channels. Is there any modifications I can do to correct this problem. Any help would be greatly appreciated. Thanks.
