Ok Here I am again.

Still with my project to have a full App_rpt controler for my 2 repeater system.

I manage to have our msr 2000 in the shack today cause the exiter is giving us some trouble.

so I said, lets fix the exiter AND plug in the URI so that I wont have to do this on site.

exiter is ok, well for now...

So I connect the URI pin 22 (mic AC) to pin 5 of the receiver inside the msr2000, why 22 there is a big dc bias at this place so uning the mic dc would nt be wise, I beleive..

now I go to the computer set active radio usb 28739

now I do radio tune rxnoise.. It fail.

there is at leat 200 mv of audio there. changed rxboosst in usbradio.conf for that node, reload, no difference.

still did the radio tune rxvoice and rxtone.

then tested without saving , I have a big white noise at the end of every receiption before the coutesy tone..

what Am I doing wrong?
