[App_rpt-users] Mastr II and URI low TX audio

I have a Mastr II mobile tuned up in the ham bands. Trying to set the audio levels. RX worked great. Problem with TX audio, I can only get 2KHz deviation max if I set the level to 999 in app_rpt. I am using the URI and have wired it to use the 6db amplifier on board. Anyone else run into this problem? boB - W5EVH
