That is off the output of U1 on the receive audio/squelch board which in two receiver kodels is a horizontal card under teh vertically slotted cards. In a single frequency model it is in position 7 There is no pin where the amplified detected audio comes out, so it requires surgery.

I know this audio in might have voltage pn it. Or that may be the tranamit side. Wait! Just noticed something important. Your rxboost=0 on 28739. The amount you're off on the level should easily be made up there. It WILL make a difference. I just tried with rxboost=0, normal for me, and noted gain at 13 for that. I changed rxboost=1, restarted asterisk and now doe the test. Level went to 32000 gain at 0 or 1, and failed. Too high. Backed it down and it was ok. My point is that rxboost WILL make a difference for you. Then it is a matter of setting squelch.

Before de-emphasis? I am looking at a manual for a MSR2000 and it shows a "variable gain amplifier (U1) which feeds the squalch detector, but alsdo feeds a low pass filter on its way to the noise gate and also feeds a de-emphasis network (U2). Any audio after that cannot have enough hi frequency component to make the setup for tune rxnoise work properly, which will not let the squelch work properly. The long squelch tail you refer to is usbradio not having its squelch set properly. And that cannot be done without wide band noise in. The result would never have enough hi freq noise at the uri to actually squelch the radio. What is eventually kmuting it is the end of input PL tone...</span><span style='font-family:"Calibri","sans-serif";color:black'><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'>Just my thoughts, but I have never had my hands on a MSR2000.
